c. CLEARING TURN: Perform clearing turns with the last 90º of turn to the right.
At the beginning of the last 90º of turn, reduce the PCL to 300 ft-lbs. of torque
and transition to a 100-KIAS descent.
At the completion of the clearing turn, apply full right rudder while using left
aileron to maintain 30º angle of bank to demonstrate the characteristics of a full
skid. Simultaneously raise the nose while reducing the PCL to 200 ft-lbs.
Increase control pressures as airspeed is reduced.
After the aircraft stalls, recover IAW NATOPS Out-of-Control Recovery
Ensure 150 KIAS is not exceeded throughout the maneuver.
Description. A slip is an out-of-balance flight condition used to increase the sink rate and
lose excess altitude while maintaining a constant airspeed and a specific track over the ground.
General. A slip occurs when the aircraft slides sideways towards the center of the turn. It
is caused by an insufficient amount of rudder in relation to the amount of aileron and the angle of
bank used. If you roll into a turn without using coordinated rudder and aileron, or if you hold
rudder against the turn after it has been established, the aircraft will slide sideways towards its
center of turn. A slip may also occur in straight-and-level flight if one wing is allowed to drag;
that is, flying with one wing low, and holding the nose of the aircraft straight by the use of
rudder pressure. In this case, the aircraft slips downward towards the earth's surface and loses
altitude. In a full slip, the rate of descent may be in excess of 2000 feet per minute.
Although the slip can be flown at any airspeed or configuration, it will be
demonstrated and introduced at altitude simulating the slip to high key at 100 KIAS
with flaps down, and gear up.
Caution must be exercised, since stall speed is increased in this
out-of-balance flight condition.
To initiate a slip from wings level, lower one wing while applying opposite (top)
rudder pressure. Select a reference point on the horizon and adjust rudder pressure
and/or angle of bank to maintain the desired groundtrack.
To initiate a slip while in a turn, lower the inboard wing while increasing opposite
(top) rudder pressure. It will be necessary to vary the angle of bank and rudder
pressure to maintain the desired track over the ground.
Monitor airspeed closely, adjust nose attitude as necessary to maintain 100 KIAS.
Monitor the VSI and note increased rate of descent.
