Inverted Spin Recovery
When using the inverted spin recovery, the aircraft recovers within a half turn after
the controls are applied. Recovery will not consistently occur if recovery controls
are applied with power. Initial recovery attitude will be in a near vertical dive. The
recommended inverted spin recovery procedure is as follows:
1. Gear, flaps, and speed brake - Retracted
2. PCL - IDLE
3. Rudder - Full opposite to turn needle deflection
4. Control stick - Aft of neutral with ailerons neutral (up to full aft stick may
be used)
5. Smoothly recover to level flight after rotation stops
CAUTION
 Power-on and inverted departures or spins will result in high loads on the
engine and torque shaft. These loads are caused primarily by the
combination of aerodynamic and gyroscopic moments experienced during
these manoeuvres.
 If an inverted or power-on departure is inadvertently encountered, the pilot
should suspect possible engine damage and may experience unusual engine
operation accompanied by low oil pressure or CHIP annunciator illumination.
 In all cases of inverted or power-on departures, the engine shall be
inspected by qualified maintenance personnel after flight.
DIVE CHARACTERISTICS
ALTITUDE LOSS IN DIVE RECOVERY
Altitude loss during dive recovery is determined by four independent factors: angle
of dive, altitude at start of pull-out, airspeed at start of pull-out, and acceleration
maintained during pull-out.
These factors must be considered collectively in estimating altitude for recovery
from any dive.
