Flight Controls Flashcards
Which primary flight controls are hydraulic?
Elevators, Rudder and roll spoilers
In a right and left hydraulic failure condition how are the elevators and rudder operated?
Elevator – manual reversion cables via trapped pressure in the PCUs.
Rudder – lower Rudder PCU via the AUX hydraulic system
Is the Yaw Damper active on the ground?
Yes, until 60 kts where it is disabled, then re-enabled with weight off wheels
Is there a trim tab on the rudder?
No, the rudder surface is deflected directly
When are ground spoilers enabled?
When switch is armed, thrust levers idle, and two of three:
WOW,
(5G) radar altimeter less than 7 feet,
wheel speed is above 16 knots.
The stick pusher can be disabled three ways
MSW (press and hold), Stall Pusher PBA off and Circuit Breaker Panel #1; number B-12
Maximum altitude with the Yaw Damper off?
31,000 feet
If the right engine driven pump (EDP) fails, what operational concerns and indications are present?
First 5° of flap are extremely slow and “flaps right low” (cyan) CAS.
How do you turn off the Roll Spoilers?
By selecting the Roll Spoiler PBA to the OFF position as directed by the checklist for a Roll Control Jam on the left side.
When the Roll Disconnect is activated who controls the Roll Spoilers and who controls the Ailerons?
The left pilot controls the Roll Spoilers on the right Pilot controls the Ailerons.
What happens when the pitch disconnect is activated?
The right and left control columns are separated. The Pilot without the jam will fly that respective side elevator.
The Gust Lock secures which controls?
Ailerons and Thrust Levers. PCU trap pressure for elevator and rudder dampening for approximately 12 hours after hydraulic pressure is removed.
Which flight controls have trim tabs?
Ailerons left side only
Which systems use primary trim?
Autopilot, Configuration Trim and Mach Trim.
How does primary trim differ from secondary trim?
Primary trim is variable speed according to trim configuration/IAS secondary trim is a constant .2°/s.
