Card Set Information
Out-of-control flight (OCF) is any flight condition in which the aircraft _____
does no respond immediately and properly to flight control inputs.
OCF can be induced by:
Improper control inputs
Overly aggressive control inputs
What are the three stages of OCF?
Failure to promptly apply proper OCF recovery procedures during the first two OCF stage will eventually result in a _____.
What are indications of poststall gyrations?
Loss of control effectiveness
Stalled or near-stalled AOA with stick shaker activated
Transient or erratic airspeed indications
Random rate-of-turn pointer indications
Describe the poststall gyration phase.
Uncommanded and often rapid aircraft motion about any axis
Could be violently spinning, tumbling or cartwheeling
Describe the incipient phase.
Motion is less random and more spin-like.
Phase last approximately two turns before progressing to a steady-state spin
Incipient spin characteristics include:
Oscillatory, rotating motion
Stalled AOA with stick shaker
Airspeed accelerating or decelerating toward the steady-state value
Rate-of-turn pointer fully deflected in the direction of the rotation
OCF recovery steps:
Check AOA, rate-of-turn pointer and airspeed
PCL - IDLE
Controls - Neutral
Altitude - check
Recover from unusual attitude
If you have not recovered from OCF by _____, ejection is recommended.
How do you know that neutral controls are becoming effective in eliminating an OCF condition?
Yaw rate decreases and the nose pitches down
How are erect spins practiced?
At 80 KIAS, full aft stick, idle power, and full rudder applied in the direction of the spin.
Erect spin characteristics:
Sustained yaw rate
AOA at or above 18
Rate-of-turn pointer fully deflected in the spin direction
Approximately 60° nose-low
2-3 seconds per turn
VSI pegged at 6000 fpm
Aispeed stabilized at 120-125 KIAS
Allow how many seconds of 1G flight prior to executing a spin maneuver?
Practice spin configuration:
Start at 120-160 KIAS
Raise the nose 15-40° nose-high
PCL - IDLE; maintain 1G
At 80 KIAS
: aft stick to maintain pitch attitude, full rudder in direction of desired spin
Nose 15-40° nose-high
Inverted spin characteristics:
Pitch approximately 30° nose low
AOA indicating 0
Rate-of-turn pointer fully deflected in spin direction
Airspeed 40 KIAS
If OCF recovery procedures are not effective on an inverted spin, what are the inverted spin procedures?
Gear,flaps and speed brake - UP
PCL - IDLE
Rudder - full opposite to rate-of-turn pointer deflection
Control stick - aft of neutral
Smoothly recover to level flight after rotation stops
What is a spiral?
Characterized by a nose-low attitude with rapidly increasing airspeed
AOA less than 18
Why is a stability demonstration performed?
To show that even from high pitch attitudes and slow airspeeds, an aircraft will not spin as long as it is not allowed to stall
Stability demonstration set up:
Raise nose to 45° pitch up
At 80 KIAS
PCL - IDLE
Neutralize the controls
Allow nose to lower until you feel positive pressures
Recover to level flight
What is the approximate practice spin entry airspeed?
Which of the following is an indication of an erect spin?
Airspeed stabilized at 120-135 KIAS
