Week 5: Stability Augmentation System Flashcards
What is the purpose of an Augmentation system?
To improve the performance and the pilot handling characteristics of an aircraft
Which of the following is a requirement for Stability Augmentation systems?
Feedback
How an airplane responds to rotation around its longitudinal axis defines its:
Lateral stability
Why is the Dutch Roll only dampened and not eliminated?
The signal to control it must come from the Dutch roll itself
What is Stability?
Ability of an aircraft to correct for conditions applied to it and return to its original flight path
_________ is the artificial improvement, by electromechanical feedback, of airplane stability and control while the airplane remains under the control of the human pilot
Stability Augmentation
What gives the aircraft Directional Stability?
Fin/Vertical Stab
The ability of the aircraft to return to its original flight path after applying rudder with the help of its fin (Directional stability) is also known as?
Weather Vane Action
Does every rudder deflection have a unique slip angle not related to air speed?
True
The aircraft will have a positive static longitudinal stability as long as what?
As long as the CofG is well ahead of the lift vector force
The ability to move the elevators and still return to your original AoA is called what?
Longitudinal Stability
What will return a stable aircraft to its trimmed AoA even if disturbed?
Trim Tabs
The trim tab provides what?
The force to deflect the control surface that the pilot would normally
Where would you want the trim tab if you wanted more stability?
Far aft
When the aircraft is turning which wing has more speed and lift and what will happen?
Outer wing = roll into turn
