Study Session 5 Flashcards
Primary flight controls
Ailerons
Elevator
Rudder
Aileron
Longitudinal axis
Controls roll
Elevator
Lateral axis
Changing pitch
Rudder
Vertical axis
Controls yaw - horizontal force
Flaps
Attached to trailing end of wing
Allows for increase in angle of descent without increasing wind speed
Spoilers
Reduce lift and increase drag
Trim systems
Relieve pilot of the need to maintain constant pressure on flight controls
Angle of attack
Angle between wing chord line and direction of relative wind
Critical angle of attack is usually around 18 to 20 degrees
Weight may have to be reduced due to
High density altitude conditions (high elevations, high temps, high humidity, low air density) Launch area Surface Slope Wind Obstacles
Load factor
Amount of lift generated to the weight of the aircraft
Load factor increases at a significant rate after a bank of 45-50 degrees
Load factor is 2 Gs in a level turn at 60 degrees
Wing chord line
Imaginary straight line from leading edge to trailing edge of the wing
Stall speed
Occurs when critical angle of attack is exceeded
Increases proportionally to the square root of the load factor
When aircraft is in bank - stall speed will increase
Ground effect
Reduces angle of attack and drag
Where will operational or performance information be found?
Aircraft flight manual or pilots operating handbook
