The document discusses the principles of aircraft stability and control. It explains that aircraft must be stable to perform well and be controllable. It then describes how yaw, pitch, and roll are controlled through use of the rudder, elevators, and ailerons respectively. Trim tabs are also discussed as a way to trim aircraft that pitch involuntarily. Flaps and slats are described as mechanisms that increase wing camber and lift, allowing aircraft to fly safely at slower speeds.
Principles of flight_chapter_3
- 1. Principles of Flight Chapter 3 – Stability and Control
- 2. Stability An Aircraft must be stable in flight in order to perform well Also we must be able to control the aircrafts movement.
- 3. Yaw Aircraft turns left or right
- 4. Controlling - Yaw Using the rudder pedals the pilot moves the rudder left or right to change the aircrafts direction.
- 5. Pitch Aircrafts noses Up or Down
- 6. Controlling - Pitch Moving the stick forwards/back lifts or lowers the aircrafts nose by generating more or less lift at the tail It uses Elevators to do this
- 8. Controlling - Roll Moving the stick left/right rolls the aircraft by generating more lift on one side. It does this by moving flaps known as Ailerons
- 9. Trimming When an aircraft pitches involuntarily it needs to be trimmed. Small flaps mounted on the Elevators called “Trimming tabs” jut out from the elevators to increase the camber. Aileron and Rudder trimming is the same
- 10. Flaps Flaps increase wing camber and/or area
- 11. Flaps Flaps allow aircraft to fly safely at slow speeds They are mounted on the inside of the wings and can hinge down to increase lift at slow speeds
- 12. Slats Like flaps at the front of the wing They slide out of the leading edge and are used at low speed Positioned on leading edge of the wing
