Flight Controls Flashcards
Primary flight controls are moved by
Rigid push-rods
Secondary flight controls are controlled by
Electro-mechanical actuators
What allows aerodynamic balance of the ailerons?
Irving diaphragms
Balance tabs (3ºangle up preset)
When pressure in aileron system drops below 61, the system
Automatically reverts to manual mode
What does the Artificial Feel Device do?
It generates tick forces proportional to the aileron deflection
The neutral point of the Artificial Feel Device is changed by
An actuator moved by the trim (it moves the neutral point of the device, hence of the ailerons)
Gust lock blocks
Elevator
Rudder
Who has the priority on trimming?
Rear inputs override the ones in the front (it also happens for speedbrake)
What type of flaps FT-339C has?
Slotted flaps
Flaps are ______ controlled and ______ actuated
