24
Q

The geometric or blank lock is mainly used as a down lock. It requires mechanical forces to unlock it; this locks can be formed by using the stays bracing the struts.

True or false : During landing and rejected take-off auto-brakes keep operating until the pilot presses the brake pedals

A

True

27
Q

True or false : There is no need for a gust lock on reversible flight controls.

A

False

28
Q

Overcentre mechanisms in landing gear systems are used to…

A

Lock the landing gear upon retraction

29
Q

The nose-wheel steering system of a jet transport aeroplane can be controlled through the rudder pedals or a hand-wheel steering (tiller). When performing a blank blank during taxiing, an additional pilot action must be taken to avoid deflection of the nose wheel.
