Term
Definition of OCF
Definition
Any flight condition in which the aircraft does not respond immediately and properly to flight control inputs
Term
OCF can be caused by
Definition
Uncoordinated flight

Improper control inputs

Overly aggressive control inputs

Structural damage
Term
3 stages of OCF
Definition
Poststall Gyrations

Incipient Spins

Steady-State spins
Term
Failure to apply proper OCF recovery procedures during the first two stages will eventually result in what?
Definition
Steady State spin
Term
Indications of poststall gyrations are
Definition
Loss of control effectiveness

Stalled or near-stalled AOA

Transient or erratic airspeed indications

Random turn needle indications
Term
Incipient spins last how many turns before turning into a steady-state spin?
Definition
2
Term
Indications of an incipient spin include
Definition
Oscillatory, rotating motion

Stalled AOA with stick shaker activated

Airspeed accelerating or decelerating toward a steady state value

Turn needle fully deflected in the direction of rotation
Term
During a practice OCF recovery, the PCL must be set to _______ before applying rudder to enter the OCF condition
Definition
Idle
Term
Recover from OCF when?
Definition
At the direction of your IP
Term
Before preforming the OCF recovery, you should check
Definition
AOA, turn needle and airspeed
Term
When physically placing the controls at neutral, you should make no attempt to counteract aircraft motions (T/F)
Definition
True
Term
If there isn't not sufficient altitude remaining (_______ AGL) and the aircraft (is/is not) recovering, an immediate ________ is recommended
Definition
6000 feet, is not, ejection
Term
Recover from the unusual attitude in an OCF recovery when
Definition
The A/C is nose low with no yawing motions

Once the aircraft is under control and gyrations stop

Confirmed the unusual attitude and apply the appropriate recovery procedure to return to level flight
Term
Erect spins are practiced with what?
Definition
Full aft stick, idle power, and full rudder applied in the direction of the spin
Term
Indications of a stabilized erect spin
Definition
Sustained raw rate

AOA at or above 18 units

Turn needle fully deflected in the spin direction

Approx 60 degrees nose low

2-3 seconds per turn

VSI pegged at 6000 FPM (400-500 feet per turn)

Airspeed stabilized at 120-135 KIAS
Term
Erect spin entry procedures
Definition
1.) 120 KIAS minimum to 160 KIAS
2.)15-40 deg nose high
3.) PCL idle
4.) Maintain approx 1 G
5.)Pitch trim set 1/2-3/4 nose up
6.)Entry at 80 KIAS
7.) Hold stick and rudder fully against the stop with neutral ailerons
Term
Recover from erect spin before
Definition
steady state spin develops (2 turns)
Term
The primary reason that an inverted spin happens in a T-6A is
Definition
The PCL is set to MAX
Term
Characteristics of an inverted spin
Definition
Approx 30 degrees nose low pitch

AOA indicating zero units

Turn needle fully deflected in spin direction

Airspeed is indicating 40 KIAS

Accelerometer is indicating -1.5 Gs
Term
During an inverted spin, reducing the power to ________ during the first two spins will typically result in spin termination w/o applying inverted spin recovery procedures
Definition
IDLE
Term
Inverted recovery procedures
Definition
Gear, flaps and speed brake- retracted

PCL- Idle

Rudder- Full opposite to turn needle deflection

Control Stick- Aft of neutral (up to full aft if necessary)

5.) Smoothly recover to level flight after rotation stops
Term
(T/F) A spiral is often mistaken for a spin. Applying anti-spin controls may not be effective in arresting a spiral and may actually aggravate the situation.
Definition
True
Term
Spirals are characterized by
Definition
Nose low attitude

Rapidly increasing airspeed (through 160 KIAS)

AOA is less that 18.
Term
Typically, spirals feel (more/less) violent that a spin
Definition
more
Term
Spiral recovery procedures
Definition
Execute OCF boldface

Ejection recommended if encountering a spiral below 6000 AGL and recovery is not imminent
Term
Stability demonstration procedures
Definition
Airspeed-160 KIAS

Power- 60% Torque

Pitch - 45 degrees

As airspeed approaches 80 KIAS recover the AC by selecting IDLE power and neutralizing controls
