Configure aircraft
Establish 120 KIAS
Increase bank, back pressure
Retard to IDLE
Recovery:
MAX, RELAX, ROLL

Establish approach speed +5 to 10 knots and configure aircraft for landing
Reduce power to IDLE
Execute a normal roundout
Hold until approach to stall indication
Recovery:
MAX, RELAX, ROLL
What are the entry procedures for the closed pullup stall? (simulator)
140 KIAS
Roll and pull to simulate over-aggressive closed pattern until approach to stall indication is recognized
Recovery:
Reduce back still pressure
Level the wings
Power reduction to 60% torque may be necessary if pattern is flown to left
ELP Stalls Clean Glide Procedures
125 KIAS glide clean (4% to torque)
Increase pitch to gear warning tone
Lower pitch below glide altitude
ELP High key to Low key Stall
Landing Gear down
30º bank 120 KIAS glide
Raise nose to stick shaker/approach to stall
Maintain turn, lower pitch to prop arc on horizon
Low key to Runway ELP procedure
Gear down, Flaps TO
30º bank 120 KIAS glide
Raise nose to stick shaker/approach to stall
Maintain turn, lower pitch to prop arc on horizon
What is the primary cause of decaying airspeed in the emergency landing pattern?
Poor glide attitude control due to:
Pilot distraction with emergency situation
Runway Fixation
Slow flight procedures
80-85 KIAS (15 units AOA)
Power to maintain level flight (~45% torque)
Maintain altitude and airspeed
Execute stall recovery if stall condition is encountered
15-20º turns while maintaining coordinated flight
How do you recover from inverted flight?
Roll in shortest direction upright toward the most sky
If nose-high and inverted, pull to horizon and roll to recover
What causes and OCF condition? What are the types of OCF?
Caused by: Stall combined with yaw Types of OCF: -Poststall gyrations -Incipient spin -Steady state spins
When is the PCL set to IDLE during a practice OCF entry?
Prior to applying rudder
Which instruments should be checked before and OCF recovery?
AOA, Airspeed, Turn Needle
What is the entry procedures for a practice erect spin?
Clear above and below
Ensure proper altitude and cloud clearances
CLEF check
Reduce power to idle and gradually increase pitch to maintain level to slightly climbing 1G flight
At spin entry airspeed:
Apply back stick
Apply full rudder
Pitch attitude at entry should be approx 15 to 40º nose high
What is the stability Demo entry?
