Dash One Sxn 6 Flashcards
What does the stab augmentor system do?
Automatically damps out yaw short period oscillations
In what Mach range may abrupt forward or aft ddeflection (pulsing) of the stick cause over-G?
Mach 0.80-0.95
What does the bobweight do?
It is a part of the horizontal tail control system and it increases stick forces under g loads but the pilot will not feel the effect of it until the aircraft responds to the stick movement.
How much stick travel provides 1/2 aileron deflection? Full aileron deflection?
4.5 inches for 1/2 aileron; 1.5 inches more for full deflection (6 inches total)
What does having an external store do?
Shifts CG forward, which results in increased rotation and liftoff speeds, less trim authority, less aerobraking and flare deceleration, and higher aft stick forces
What is the best airspeed to maintain at a minimum until configuring for maneuvering and handling qualities?
300 KCAS
Where do minimum stick forces per g occur?
At approximately Mach 0.9
Where can you have severe pilot induced oscillations?
High subsonic low altitude flight
How should you fix pilot induced oscillations if you encounter them?
Release the stick to allow the aircraft to damp itself out, or if at low altitude or close to another aircraft, hold back pressure on the stick. Also reducing a/s will help
What’s more effective at low AOA?
Ailerons
What’s more effective at high AOA?
Rudders
What’s a caution with using rudder with the gear down?
Using sustained 30 deg rudder deflection at high AOA may result in violent roll and engine flameout
What limits should you use to evaluate an over-g for jetwash?
Asymmetric
What indicates the stall for this aircraft the most?
A very high sink rate and airframe buffet
How should you correct post stall gyrations?
Neutralize the controls smoothly until the aircraft recovers
How do you do a high-speed dive recovery?
Throttles IDLE, open speed brake, level wings, pull with sufficient g to recover
Do spins every happen in this aircraft?
No. Test pilots couldn’t do it Would need abrupt application of aft stick at close to maximum rates within an impossible envelope.
What is the primary anti-spin control?
Aileron
How do you recover from an impossible-to-get-into spin?
Full aileron in direction of spin and as much aft stick as possible, rudder full opposite of turn, do not change configuration, and neutralize controls after recovery
How do you recover from an inverted spin?
Neutralize all flight controls
For a high Mach 60 deg dive altitude loss includes what time allowance?
4 sec for load factor to build up to 4 Gs
Initiate dive recovery for a high speed dive recovery NLT what?
26,400’ for 45,000’ entry and 27,800’ for 50,000’ entry
What determines the subsonic lift limit? Supersonic lift limit?
Buffet; horizontal tail deflection
