Which of these statements about an auto brake system are correct or incorrect 1 an auto brake system can function properly even when anti skid system inoperative2 in rto mode maximum anti skid braking applied ) incorrect 2) correct. Proper functioning of an auto brake system requires proper functioning of anti skid system in rto (rejected take off) mode maximum anti skid braking applied the 'regulation of slip ratio' function of an anti skid system ensures optimum braking performance using rto mode provides best stopping performance during a rejected take off (the deceleration will not be constant it will increase as speed decreases).

Axial piston pumps are often used in hydraulic systems due to Their ability to produce high pressure when required but can be off loaded to reduce power consumption. high pressure large flow are symptomatic of a hydraulic system axial piston pumps can produce high pressure but can be off loaded to reduce power consumption.


17
The trim tab Reduces hinge moment control surface efficiency. The trim tab reduces hinge load because it uses tab to move control surface so there no external load imposed the pilot it reduces control surface effectiveness because it using part of control area trimming leaving less manoeuvre.


18
The purpose of a trim tab device to Reduce or to cancel control forces. A trim tab a small adjustable hinged surface on trailing edge of aileron rudder or elevator control surfaces trim tabs are labour saving devices that enable pilot to release manual pressure on primary controls some airplanes have trim tabs on all three control surfaces that are adjustable from cockpit others have them only on elevator rudder some have them only on elevator some trim tabs are ground adjustable type only the tab moved in direction opposite that of primary control surface to relieve pressure on control wheel or rudder control for example consider situation in which we wish to adjust elevator trim level flight ('level flight' the attitude of airplane that will maintain a constant altitude ) assume that back pressure required on control wheel to maintain level flight that we wish to adjust elevator trim tab to relieve this pressure since we are holding back pressure elevator will be in 'up' position the trim tab must then be adjusted downward so that airflow striking tab will hold elevators in desired position conversely if forward pressure being held elevators will be in down position so tab must be moved upward to relieve this pressure in this example we are talking about tab itself not cockpit control rudder aileron trim tabs operate on same principle as elevator trim tab to relieve pressure on rudder pedals sideward pressure on control wheel respectively.

The advantages of fly wire control are 1 reduction of electric and hydraulic power required to operate control surfaces2 lesser sensitivity to lightning strike3 direct and indirect weight saving through simplification of systems4 immunity to different interfering signals5 improvement of piloting quality throughout flight envelopethe combination regrouping all correct statements Reduce or to cancel control forces. The power required to operate control surfaces remains same fly by wire (fbw) a system that replaces conventional manual flight controls of an aircraft with an electronic interface the movements of flight controls are converted to electronic signals transmitted wires (hence fly by wire term) flight control computers determine how to move actuators at each control surface to provide ordered response the fly by wire system also allows automatic signals sent the aircraft's computers to perform functions with or without pilot's input as in systems that automatically help stabilize aircraft.

An artificial feel unit necessary in pitch channel when The elevators are actuated irreversible servo control units. Irreversible system fully powered system pilot has no direct connection to control surface he has no feel so an artificial feel system must be included this system works in parallel to irreversible servo control unit reversible system power assisted system (similar to power assisted steering a car) pilot feel a part of load he receives assistance from hydraulic system to move control surface.
