Flight Control Flashcards
On a flap slab interconnect failure, normally execute a no flap landing. If some flaps are needed to decrease landing distance and improve aerobraking use ___ to ___ %.
30 to 45
General checklist flow for abrupt and uncommanded aircraft pitch up, flaps extended
- Bench press, 60
- Gear up when continued flight is assured
- Flaps up above safe no flap flying airspeed
- Land via no flap
For abrupt and uncommanded aircraft pitch up, flaps extended, how long do you have to react to ensure recovery without loss of altitude?
3 seconds
General checklist flow for uncommanded smooth pitch-up during flap extension
- Flaps - Reposition to up
- Throttles - As required to maintain above safe no flap flying airspeed
- Land no flap
What airspeeds should you use in the pattern when flying at less than 60% flaps?
Fly AOA on speed indications in final turn
General checklist flow for flap assymetry
- Throttles - MAX
- Flaps - Actuate to eliminate (or minimize) asymmetry
- Airspeed - Above 180 KCAS
- AUX FLAP switch - EMER
Additional checklist item for flap assymetry: if asymmetry persists
- Airspeed - Maintain 20 knots above final approach and touchdown speed. Do not touch down below 165
General checklist flow for runaway trim
- Hold trim in the opposite direction of trim tab movement
2. TRIM CONTROL circuit breaker - PULL (FCP pedestal)
The stability augmentor system can fail with a resulting rudder deflection of __ degrees
2
What is the appropriate action for a full 30 degree rudder hardover
Use full aileron and rudder to try to control the airplane
It won’t be controllable
Eject
When should you eject from a spin?
Upon reaching 6000 AGL uncontrollable or
When transverse g loads preclude maintaining anti-spin controls (whichever occurs first)
Erect spin recovery procedure
- Control Stick - Fully deflected in direction of spin and as far aft as possible without sacrificing aileron deflection
- Rudder - Full opposite
- Don’t change configuration (gear, flaps, speed brake)
- Neutralize controls after recovery
Inverted spin recovery procedures
All flight controls - neutralize
What is different about landing with any structural damage?
Do not aerobrake. Hold landing attitude until loss of slab authority. This could increase landing roll by as much as 50%.
What speed should you slow to on a controllability check?
Min controllable airspeed or touchdown speed, whichever occurs first.
As a guide, if you have to deflect the stick more than 3/4 stick travel to maintain level accelerated flight, you have reached min controllable.
Touchdown speed is generally +-5 knots of level flight stall speed. In no case allow airspeed to decrease below touchdown speed.
