Define aircraft stability - correct answer✔✔The stability of an aeroplane means its ability to
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




return to some particular condition of flight (after having been slightly disturbed from that
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




condition) without any effort on the part of the pilot. ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




Define static stability - correct answer✔✔the initial tendency that an object displays after
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




its equilibrium is disrupted
||\\//|\ ||\\//|\ ||\\//|\




What are the three types of static stability? - correct answer✔✔positive, negative, neutral
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




What is positive static stability? - correct answer✔✔The tendency of an aeroplane to return
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




to its original attitude after displacement.
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




What is negative static stability? - correct answer✔✔The tendency of an aircraft to move
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




farther away from the original attitude following a disturbance.
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




What is neutral static stability? - correct answer✔✔If an aeroplane tends to remain in its
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




displaced attitude, it has neutral static stability. Static stability may also be called passive ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




stability where no active control is needed by the pilot or device to maintain aircraft
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




stability



Describe positive dynamic stability: - correct answer✔✔If an aeroplane tends to return to
||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\ ||\\//|\




the original attitude directly, or through a series of decreasing oscillations, it exhibits
