Be guarantee aircraft ground taxi, turning, normally landing, take off, landings that overload, suspension take off and ground stop and engine
Brake when test run.
For pilot when manipulating brake system, hydraulic oil enters the braking action cylinder being fixed on wheel shaft, pushes brake block,
Compress movable plate and stationary plate.Due to the rubbing action between rubbing surface, the torque for preventing wheel from rolling is increased, so wheel exists
The frictional ground force being subject in rolling significantly increases, and the running speed of aircraft reduces therewith.Driver's brake is heavier, into brake
Oil liquid pressure in pressurized strut is bigger, also just presses tighter between brake block, and the torque for preventing wheel from rolling is bigger, thus makees

A brake fan swicth is added, this is because brake fan swicth could be beaten only when main landing gear is grounded and is locked
It opens, and before aircraft standby for takeoff, and have to a brake fan swicth and close.In addition, due to having installed brake fan additional, because
And the software and hardware of brake control unit will be embedded in the operational order of brake fan, display information, warning information etc., and
It also needs to dismantle main gear wheels hub cap to be changed to brake fan, and needs to access power supply for brake fan so that it is transported
Turn.However, once brake fan breaks down, normally sending for aircraft will be caused to severely impact.It is more bad,
During aircraft cruising flight, which is at all inoperative, and can only occupy the efficient loading weight of aircraft,
