 Review and understand airfield signage and markings.
 Review the most up-to-date airport diagram prior to moving
the vehicle. Have the airport diagram out and available for
immediate reference while driving in the operational area.
 Review current airfield information for any taxiway closures,
runway closures, construction activity or other surface risks.
 Ensure appropriate vehicle lights (high beams, flashers,
beacons and strobes) are operational prior to driving on the
airport surface. Flashers and beacons help ATC, aircrews and
other operators see vehicles in the movement area, especially
during periods of reduced visibility and at night.
 Use service roads whenever possible to minimize time spent
on taxiways and runways.
 During radio transmissions, use proper aviation phraseology
and speak in a clear, concise manner.
 Copy your clearance and review the assigned route. Read back
all clearances.
 If you do not understand an instruction, clarify with ATC
before proceeding.
 While driving, refrain from using cell phone, texting or
engaging in unnecessary conversation.
 Get as familiar as possible with the airport's roads, taxiways
and runways before driving solo on the airfield. If possible,
have someone who is very familiar with the airport
accompany you until you are proficient at operating on the
movement area.
Traffic levels rise, airports expand, surface routes change,
and you, the vehicle driver, are expected to understand how
to safely move about the airport. Besides learning about
the different movement areas on the airport, the added
combination of changes in weather, time of day and amount of
aircraft traffic makes the risk of error higher than ever.
Runway incursions are a serious safety concern and significantly
impact safe operations at any airport. Incursions, which
also can occur on taxiways although not considered runway
incursions, have involved air carrier aircraft, military planes,
general aviation aircraft, air traffic controllers, ground vehicles
and pedestrians.
A Runway Incursion (RI) is defined as any occurrence at an
aerodrome involving the incorrect presence of an aircraft,
vehicle or person on the protected area of a surface designated
for the landing and takeoff of aircraft. There are three types
of RIs: Operational Errors (OE), Pilot Deviations (PD) and
Vehicle/Pedestrian Deviations (V/PD).
Operational Errors involve air traffic control (ATC) and Pilot
Deviations typically involve an airman's mistake. A V/PD
occurs when a vehicle or pedestrian has entered the runway
safety area without authorization from air traffic control.
Annually, V/PD's comprise approximately 20% of total runway
incursions.
The information presented in this brochure is focused on
helping to inform and educate vehicle drivers about the various
signs, lights, markings, phraseology and other procedures
utilized in an airport environment. Listed below are some basic
things to remember and practice before operating a vehicle on
the airport:

Introduction
The FAA Guide to Ground Vehicle Operations was created
for you, the driver of a tug, fuel truck, baggage cart or
other airport vehicle. This guide is not intended to provide
comprehensive coverage of everything there is to know about
surface safety. Rather, it focuses on five areas that are most
important, as well as containing additional information and a
chance for you to test your overall comprehension with a quiz.
Each section identifies safety measures and information that
will help you maintain situational awareness while on the
airfield. “Situational awareness” is defined as being aware of
your location on the airfield and how that location relates
to your destination, other vehicles and aircraft. It can be
maintained consistently by:
 Understanding and following Air Traffic Control (ATC)
instructions and clearances.
 Using an airport diagram.
 Knowing the meaning of the visual aids available on the
airport, such as airfield markings, signs and lights.
Maintaining situational awareness will help you avoid errors
that lead to runway incursions. Runway incursions are a
serious safety concern and it doesn’t take much to be involved
in one. Incursions and collisions have included all types of
commercial, military and private aircraft as well as GROUND
VEHICLES. Some have resulted in fatalities. All employees who
operate vehicles or motorized equipment on airports have key
responsibilities in these safety efforts, as this guide outlines.

Airport Basics
Airport Basics
AIRPORT BASICS
This section outlines the basic features of any airport. There
may be important unique aspects to the airport on which
you drive, such as dedicated vehicle lanes, areas not visible to
controllers or nonstandard airport traffic patterns. Be aware
and know the rules of your airport.
Runway Safety Area
The Runway Safety Area (RSA) is an area surrounding the
runway, and is measured from the runway ends and centerline.
Much like the shoulder area on a highway, the runway safety
area is intended for use by aircraft in emergency situations,
i.e., landing short of, veering off of, or overshooting the
runway, and always should be free of vehicles, equipment and
pedestrians any time aircraft are taxiing, taking off or landing.
When the tower is in operation, vehicles and pedestrians are
required to have clearance to access these areas. During periods
when the tower is not operating or at a non-towered airport,
extreme caution should be used.
The RSA can be identified by a hold line, also known as a
holding position marking, which is painted in yellow on taxiway
surfaces and collocated with a holding position sign. The holding
position sign has a red background with white characters. The
actual dimensions of the RSA will vary depending on the tail
height and wing span of the largest aircraft authorized to utilize
the airport. Its
distance from the
runway centerline
may extend up to
280 feet across and
as much as 1,000 feet beyond the runway ends.
Aprons/Ramps
Aprons, also called ramps, are the areas where aircraft park, load and
unload. Your work may require you to drive on an apron. In addition
to watching for moving aircraft on the apron, be careful to maintain a
safe distance when working around
parked aircraft. Aside from nicks and
dents that are expensive to repair and
can affect the airworthiness of the
aircraft, you could get hurt and your
vehicle damaged when an aircraft
starts its engine. This hazard is called
jet blast or prop wash. There have been several cases where vehicles have
been overturned by jet blast. Drivers should be aware of the rotating red
beacon(s) located on the aircraft's tail, and sometimes on its underside.
The beacon is typically illuminated in conjunction with imminent
engine start.
Runway Markings are WHITE
Runways have white numbers on each end, centerline stripes
down the middle and may have white lines along the edges.
Runways that are served by an instrument approach will have
more elaborate markings such as those shown in Figure 1.1.
Figure 1.1 – Runway Markings (not to scale).

Airport Basics
Airport Basics
Taxiway Markings are Yellow
Taxiways are areas used by aircraft to get to and from the
apron/ramp and the runway. Taxiways look similar to runways,
but are usually not as wide. Instead of numbers, taxiways use
letters or letter/number combinations for designators. See Fig-
ure 1.1
BEST PRACTICES FOR SAFE DRIVING
On the Movement Areas
 Together, runways and taxiways are known as the
MOVEMENT AREAS of the airfield.
 Airport diagrams provide the layout and designations of
runways and taxiways, show the location of major facilities
and are essential to navigating the airfield surface. Always
have a current airport diagram in your vehicle.
 If you are required to drive on or work in areas adjacent to
runways, be aware that aircraft wings and engines may extend
over these areas. ATC approval is typically required to operate
in these areas.
 If you become uncertain of your location on the airport
movement area, STOP and immediately contact ATC for
help.
 Know your airfield markings, signs and lighting (as outlined
in the next section). Be careful not to hit taxiway edge lights.
Around Aircraft
 Aircraft cockpit windows have a limited viewing area. It
can be difficult or impossible for pilots to see vehicles and
pedestrians, particularly behind the wings or under the nose
of the aircraft.
 Always yield the right-of-way to moving aircraft. Do not
assume the pilot will see you, especially in busy areas like
aprons/ramps where pilots are busy with preflight checks.
 If a pilot is about to start the engine or the engine is running,
the aircraft’s red rotating beacon(s) should be turned on as
well.
While Communicating with Air Traffic Control (ATC)
 Avoid distractions and focus on where other vehicles and/or
aircraft are on the airfield, especially on your intended route.
 Always use standard aviation phraseology and proper
communications procedures when contacting ATC in order to
facilitate clear and concise communications.
 Write down taxi instructions, especially instructions that are
complex. This can help reduce your vulnerability of forgetting
part of the instruction.
 When in doubt, STOP and ask for help or clarification from
ATC.
EXPLICIT RUNWAY CROSSING CLEARANCES: Never
cross a holding position marking including hold lines for
inactive or closed runways without explicit ATC instructions.
Instructions to cross a runway will be issued one at a time.
An aircraft or vehicle must have crossed the previous runway
before another runway crossing is issued.

10 11
When exiting a runway, you will see these same markings, except
your vehicle will be approaching the dashed lines. Your vehicle
must completely cross both the dashed and the solid lines to be
clear of the runway.
SIGNS AND MARKINGS
As a driver, it is important that you know the meanings of the signs
and markings used on airports as navigational aids. Sometimes the
information on the sign is also painted on the airport pavement.
An overview of some of the most common signs and markings is
described on the following pages. For more detailed information,
see the FAA Aeronautical Information Manual (AIM).
Runway Holding Position Marking
Painted yellow on the taxiway pavement and collocated with the
holding position sign, this is an airport version of a stop sign.
As you approach the runway, you will see two solid yellow lines
with two dashed lines. Prior to
reaching the solid lines, it is
imperative that you STOP and
do not cross the lines until you have clearance from ATC. When the
tower is closed or you are operating at a non-towered airport, you
may cross only when the runway is clear of aircraft, and then cross
with extreme caution. Always look both ways before you cross any
runway!
Runway Holding Position Sign
May be seen as a sign and/or painted on the
pavement, it has white characters on a red
background. This sign/marking is collocated
with the surface painted holding position
markings on taxiway and runway intersections.
Airport Basics
During Construction
 Extra vigilance is necessary when driving on an airport during
construction. Normal driving routes may be altered, runways and
taxiways may be closed, runway thresholds may be displaced or
relocated and hot spots may be identified. Therefore, remember to
review your expected driving route against areas of construction,
especially if you are operating a rescue vehicle.
Hot Spots
 ICAO defines a hot spot as a location on an aerodrome
movement area with a history or potential risk of collision or
runway incursion, and where heightened attention by pilots and
drivers is necessary.
 A hot spot is a runway safety
related problem typically
at a complex or confusing
taxiway/taxiway or taxiway/
runway intersection. As
a vehicle driver, it is your
responsibility to be familiar
with these areas and use
extreme caution when driving
in, or near them. The airport
diagram will usually, but not
always point out designated
hot spots. Be certain to use
the most up-to-date diagram
as hot spots will remain
charted until such time
the increased risk has been
reduced or eliminated.
For more information on hot spots, refer to the Airport Diagrams
chapter in the Airport Facility Directory (AFD). Also visit:
www.faa.gov/airports/runway_safety/hotspots/hotspots_list

12 13
Holding position markings for ILS critical areas appear on the
pavement as a yellow horizontal ladder and extend across the width
of the taxiway. An ILS holding
position sign with white characters
on a red background is typically
situated adjacent to these ILS holding position markings. Hold
short of this area when instructed to by ATC.
ILS Boundary Sign This sign identifies the boundary of the ILS
critical area for pilots and vehicle operators
exiting the runway. Pilots and vehicle
operators must proceed beyond this sign to
clear the ILS critical area when instructed to
do so by ATC.
Non-Movement Area Boundary Markings
A single solid line along with single dashed yellow lines, this
marking divides the movement and non-movement areas on the
airfield. When you are positioned on the solid line side of the
marking, or the non-movement area,
ATC clearance is required for you to
drive across into the movement area.
Runway Safety Area Boundary Sign Yellow sign with black
markings. Visible only when exiting the runway. The sign is
typically used on towered airports where a controller commonly
requests a pilot to report clear of a runway, which occurs when this
sign is passed.
Do not drive past this sign or marking without a clearance from ATC.
Doing so without clearance from the tower poses a hazard to yourself
and others. When the tower is closed or you are operating at a non-
towered airport, you may cross only when the runway is clear of
aircraft, and then you should proceed with extreme caution.
Location Signs and Markings Black
background with yellow letters and/
or numbers. These signs and surface-
painted markings indicate your location.
REMEMBER: BLACK SQUARE, YOU’RE THERE. (See Figure 2.1)
Taxiway Direction Signs and Markings These signs and
markings with a yellow background and black
characters indicate the direction toward a
different taxiway leading off a runway or out of an
intersection. YELLOW ARRAY, LEADS THE WAY.
(See Figures 2.1 and 2.2)
ILS Critical Area Holding Position Signs and Markings
May be seen as a sign (as shown here), and/or as a
painted surface marking. These are utilized to show
the boundary of the runway's ILS critical area. Hold
short of this area when instructed to by ATC.

Geographic Position Markings Pink with
black and white. Some large airports use
these markings in low visibility conditions as
position points on the taxiway.
Helicopter Landing Area Marking Some airports have a
designated helicopter landing pad. This area is depicted with an
“H” inside of a square. Be especially careful when you
drive near helipads. Look up for landing helicopters.
As is the case for aircraft, yield the right-of-way to a
helicopter.
Destination Signs Yellow background
with black letters. The taxiways at your
airport may have these signs next to them
to identify the direction to a specific
destination, e.g. parking area.
Enhanced Taxiway Centerlines A dashed line painted on each
side of the existing taxiway centerline
extending up to 150' from the holding
position marking. This is to further
alert aircraft and vehicles that they are
approaching a runway safety area.
Relocated Threshold A point on the runway other than the
beginning of the full strength pavement, which is not available for
the landing or takeoff of aircraft. Thus, a relocated threshold marks
the end of the runway. The abandoned
runway area may or may not be available
for taxiing. Possible causes for threshold
relocation include construction or other
airport maintenance.
Chevrons Large yellow painted arrows that identify paved blast
pads, stop areas, and EMAS (engineered
materials arresting systems). A minimum
of two chevrons will be painted and
aligned with the runway end. The
pavement marked by chevrons is not to
be used, unless in conjunction with an
EMAS when it may be used to help stop an aircraft overrun.
Aprons/Ramps
Aprons/Ramps have markings for aircraft parking and tie-downs.
Some airport aprons/ramps also have special markings for vehicle
operations. If there are vehicle or roadway markings, you should
always drive your vehicle within those marked areas. In addition,
taxiways may be marked on the apron to show aircraft routes to
gates and parking areas.
Examples of vehicle surface markings; roadways bounded by “zipper”
markings are also used by aircraft.

16 17
LIGHTING
There are many different lighting combinations that may be
located on some airports, especially where aircraft operations are
conducted in lower visibility ranges.
Runway Edge and Centerline Lights Runway edge lights are
clear/white, except on instrument runways
where yellow replaces white on the last 2,000
feet or half the runway length, whichever
is less, to form a caution zone for landings.
Centerline lights alternate red/white starting
3,000 feet from the end, and are solid red
starting 1,000 feet from the end.
Taxiway Edge Lights or Reflectors are blue in color and used
to outline the edges of taxiways during periods of darkness or
restricted visibility conditions.
Taxiway Centerline Lights or Reflectors are
green except for the lead-on and lead-off lights,
which alternate yellow and green to indicate
that you are entering or leaving the runway
environment.
Runway Guard Lights are flashing yellow lights that can be
in-pavement or elevated and are used to help identify a runway
holding position.
Runway Status Lights (RWSL) provide a visual warning to vehicle
drivers and pilots that the runway is not safe to enter. RWSL consist
of the following warning signals: runway entrance lights (REL) and
runway intersection lights (RIL) for vehicles and aircraft crossing or
entering a runway from intersecting taxiways or runways, and takeoff
hold lights (THL) for aircraft awaiting takeoff. The system will be
operational at 23 of the nation's major airports by the end of 2015.
When driving near navigational aids, stay out of the protected
areas around them to avoid interfering with their signals. If
a road or taxiway is close enough to an ILS to affect it, there
should be an ILS holding position sign like the one depicted on
page 12.

Towered Airports
TOWERED AIRPORTS
If your airport has an air traffic control
(ATC) tower, it is a towered airport
whenever the tower is operating. Pilots
and vehicle drivers wanting to enter a
runway or taxiway (movement areas)
must first get permission from the
tower.
As an operator of a vehicle, you must
have authorization from ATC before
you enter any part of the airport
movement area. When the tower is in
operation, you must utilize a two-way
radio for communicating with and receiving instructions from air traffic
control.
Radio Communications Procedures
 Ensure the availability of a radio capable of transmitting and
receiving on the airport’s ground control frequency. Perform a
"radio check" to assess your radio's operability at the start of
each shift.
 Each vehicle should be designated with an identifying call
sign, and be marked and lighted appropriately.
 Know the standard Air Traffic Control (ATC) phraseology
and never use Citizen’s Band (CB) lingo or law enforcement
‘ten’ codes.
 Think about what you are going to say before calling the
controller. Know your call sign, location on the airfield and
where you intend to go.

Light Gun Signals
VEHICLE LIGHT GUN SIGNALS
Air traffic controllers have a backup system for communicating if
radios fail. Controllers use a light gun that flashes different colors
to tell pilots or vehicle drivers what to do. Even a failed radio is not
an excuse for proceeding without a proper clearance. If you are ever
working on a runway or taxiway and radio communication fails,
you should:
 Turn your vehicle toward the tower.
 Flash your headlights.
 Wait for the controller to signal you with the light gun.
 Be patient! If the controller’s attention is directed toward
another part of the airport, it may take a few minutes.
 If still waiting, try a different radio frequency or call from a
cell phone. Store the tower phone number in your cell phone
for emergencies.

20 21
The “Aviation
Terminology” section on
page 25 lists air traffic
control terms and phrases
with definitions. You
should know what they
mean before driving on an
airfield.
With a little practice, radio communications are not difficult. If you are
ever unsure about what the controller said, or if you don’t understand
an instruction, ask the controller to repeat the communication by
transmitting “SAY AGAIN” .
A controller, even one who is extremely busy, would rather repeat and
explain instructions than have a misunderstanding lead to a runway
incursion. Don’t proceed thinking that the instructions will become
clear once you drive a little farther.
Advance Coordination
When you contact the tower before an operation, you will receive
instructions on how to proceed. Be sure you understand your
route, stopping points and holding positions. If you are not sure
where you are going and would like turn-by-turn directions, ask
the controller for “progressive” taxi instructions.
Use extreme caution when you hear the phraseology “go
ahead”. It is only meant for you to proceed with your message
and is not to be used for any other purpose. It NEVER means
to proceed in moving about, or to drive on the airfield.
Towered Airports
Towered Airports
 At most facilities, the above information can be included on
the initial call as in the following example:
 At larger facilities or when the controller is busy, it is best to
simply call the tower with your identification and wait for the
controller’s response as in the following:
 Read back of all runway holding instructions is required
and must include the phrase "Hold Short", the runway's
identifying number and your call sign.
Driver: Cincinnati ground, vehicle one at gate four
would like to cross runway one eight right at
taxiway alpha and proceed to the VOR.
Controllers: Vehicle one, Cincinnati ground, proceed via
alpha, hold short of runway one eight right.
Driver: Roger, vehicle one, proceeding via alpha, will
hold short of runway one eight right.
Driver: Cincinnati ground, vehicle one.
...time elapses...
Controllers: Vehicle one, Cincinnati ground.
Driver: Vehicle one at gate four would like to cross
runway one eight right at taxiway alpha and
proceed to the VOR.

22 23
 Before you cross a runway, ensure that no potentially
conflicting aircraft are taxiing, landing or taking off. Be
aware of aircraft at non-towered airports that frequently make
touch-and-go landings (immediately after landing, full power
is applied and the aircraft takes off again).
 If your vehicle has a rotating beacon, be sure to turn it on
anytime you are on the airport surface. Turn on headlights as
well, being careful not to blind any pilots in the area.
Traffic Patterns
Aircraft approaching a runway for landing usually follow a standard
landing pattern. Most runways are positioned so planes will take off
and land into the wind. In most cases, the pattern is a rectangular box
with the pilot making all turns to the left, as shown in Figure 3.1.
In a few cases, airports will use right traffic patterns. However, don’t
assume all aircraft will always be flying in the standard pattern - it is not
required, only recommended - so keep a visual look out to the sky just
Pilot: Millville traffic. Cherokee two zero niner zero
whiskey, entering left downwind runway one zero,
Millville.
NON-TOWERED AIRPORTS
When the control tower is closed or if there is no tower, the airport
is referred to as non-towered. At a non-towered airport, you do not
need controller permission before entering a runway or taxiway.
Below are some best practices for operating on a non-towered
airport:
 When you approach the runways and taxiways, STOP, LOOK
both ways, and LISTEN for aircraft that are landing or taking
off. Vehicle windows should be open to do this properly.
 Alert others when you are using a taxiway or runway by
always making an announcement on the radio before you
enter. Be specific with your location and intentions.
 Always yield the right-of-way to taxiing aircraft and give them
plenty of room. If an aircraft is headed toward you on the
same taxiway, move out of the aircraft’s way.
 Always carry a radio tuned to the airport’s Common Traffic
Advisory Frequency (CTAF) or UNICOM.
 If an aircraft is about to land on a runway that you need to
cross, stop well clear of the runway. Continue to yield to the
aircraft until it has landed and taxied off of the runway.
 Be aware that some
aircraft at non-towered
airports are not equipped
with radios.
Example of a self-announcement by driver on
UNICOM or CTAF:
Driver: Millville traffic. Ops one vehicle entering runway
28 at approach end and proceeding full length to
the end of the runway.

AVIATION TERMINOLOGY
This section contains a glossary of terms commonly used in
ground or surface operations. For a complete listing of all ATC
phraseology, consult the FAA Aeronautical Information Manual
(AIM), which can be accessed at: http://www.faa.gov/air_traffic/
publications/atpubs/aim/
Acknowledge - Let me know that you have received and
understood this message.
Advise Intentions - Tell me what you plan to do.
Affirmative - Yes.
Confirm - My understanding of your transmission is ______ :
Is that correct?
Correction - An error has been made in the transmission and
the correct version follows.
Final - Commonly used to mean that an aircraft is on the final
approach course or is aligned with a landing area.
Go Ahead - Proceed with your message. Not to be used for any
other purpose.
Hold or Hold Position - Stay in place where you are currently
located.
Hold Short of… - Proceed to, but hold short of a specific point
and maintain appropriate distance to avoid interfering with
other traffic. With respect to runways, always stop at the runway
in case a pilot decides to fly a ‘straight in’ approach and doesn’t enter
the standard traffic pattern. Similarly, if a pilot announces "short final",
expect that aircraft’s landing to be imminent.
Pilots announce their position on the Common Traffic Advisory
Frequency (CTAF)/Unicom using the names of the segments of the
traffic pattern: Upwind, Crosswind, Downwind, Base and Final.
See Figure 3.1
Extra vigilance is essential at non-towered airports, or when
the control tower is not operating. While there may be CTAF
or UNICOM frequencies available, pilots are not required to
communicate or announce their position in the traffic pattern or
on the surface. As a result, a driver can be lulled into complacency
because the airport is not very busy. Nevertheless, always remain
alert for the unexpected, even when aircraft traffic levels are light.
Another factor involves the runway angle or slope, which makes
it difficult or impossible to see the entire length of the runway.
As a result, an aircraft can suddenly appear on a runway when
you are crossing. Generally, it is good practice to cross runways
at their ends. If one is available, a perimeter road or taxiway is
the recommended route for crossing a runway at a non-towered
airfield.

28 29
All vehicles operating at a towered airport, including
ARFF and police, are required to receive explicit runway
crossing instructions from ATC. This applies to all runways
encountered: active, inactive and closed, regardless of the type
of emergency!
Reporting Accidents
If you are involved in an accident, report it immediately. If a
collision occurred between you and an aircraft, it’s critical that
the aircraft not be flown until the damage can be inspected and
repaired.
Aircraft Rescue and Fire Fighting (ARFF)
Just as when you are in highway traffic, if you see an airport
emergency vehicle with its lights on, do not proceed until it has
cleared. Always stay alert for any type of emergency activity and
accompanying vehicles.
ADDITIONAL INFORMATION
In addition to all the information provided to you in this
publication, there are other things to be aware of while operating a
vehicle on the airport.
Foreign Object Debris (FOD)
Trash or rocks sucked into a jet engine can shred parts of the
engine in seconds. A rock caught by a propeller can damage the
propeller, as well as become a deadly projectile. Make your airport
a safer place by putting all trash in a covered container that won’t
be blown over. Get in the habit of picking up any trash and debris
that you notice while driving around the airport. Avoid tracking
mud and rocks onto taxiway and runway surfaces.

30 31
Nighttime or Bad Weather Driving
If you are required to drive on the airport at night, on your first
couple of trips take someone along who is very familiar with the
airfield. Things look different at night. The same applies if you are
driving in bad weather. In both cases, allow yourself extra travel
time and drive slower than you would normally. Remember, your
vehicle’s rotating beacon and headlights will provide additional
visibility and help to identify your vehicle to others.
During winter conditions, signs and markings may be obscured
by snow. Snow equipment may be operating in low visibility
conditions and may not see your vehicle. Use caution; remember
there are extra risks present.
This guide has covered the basics of how to safely drive on an airport.
Remember to be courteous to your fellow drivers, pay attention, drive
carefully, follow instructions, avoid distractions, obey the rules and
regulations and set a good example. Eventually, with experience, you
will attain a comfortable working knowledge of how to safely move
around.
Security
Depending on the type of airport you work on, the security system
may be as simple as a fence or it may include items as complicated as
computer controlled automatic gates with television screen monitors.
At large air carrier airports, security will be provided by the airport’s
police department or local law enforcement. At smaller airports, the
airport manager or the fixed-base operator may be responsible for
security.
If you see a gate left open, close it, and then report it to the airport
security office. Never let someone follow you through a gate. If
you see a strange person or vehicle that appears lost, stop and offer
assistance. Or, if your airport has a security department, contact
them for help. If you work at an air carrier airport, the airport
manager has a complete security plan of the airport with detailed
procedures for specific situations. Be sure you know what your
responsibilities are and ask your supervisor if there is anything
about which you are unsure.

Conclusion
If there is something you don’t understand, seek clarification before
proceeding, especially when you are at a towered airport with an
operating ATC tower. With experience, you will attain a comfortable
working knowledge of moving about the airport surface safely. Always
maintain situational awareness and contact ATC if you are unsure, lost
or unclear of an instruction.
