T-34C OUT-OF-CONTROL FLIGHT
IUT shall report altitude, AOA, airspeed, and turn needle following spiral entry.
OCF IP will maintain pro spiral control inputs until airspeed has reached 120
knots, but no greater than 150 knots.
Initiate OCF Recovery Procedures upon IUT recognition of spiral or no later
than airspeed reaching 150 knots, or 7000 feet AGL (whichever occurs first).
This maneuver is a demonstration only and will not be performed by the IUT.
Recover from ensuing unusual altitude.
Recovery airspeeds will be in excess of 200 knots with recovery
initiated at 150 knots.
Failure to initiate recovery by 150 knots will result in
extremely rapid airspeed buildup and high rates of descent. The
possibility of asymmetrical "G" loading during the pullout exists
due to the extremely disorienting effects felt during a spiral
Care must be taken not to overspeed the flaps.
The Slip/Skid Departure Demo
Description: This maneuver demonstrates the characteristics of the stall and
departure of the aircraft in a slip and skid.
General: The maneuver lets the IUT analyze the AOA and departure airspeeds under
different flight conditions (i.e., slip versus skid and accelerated versus unaccelerated).
The maneuver emphasizes the reason we fly the aircraft in a slip vice skid and how
acceleration will affect the airspeed at departure. Fly the slip demo first, climb back
to altitude, and repeat for skid.
This maneuver is demonstration only and will not be performed by
the IUT. The IUT will focus on various AOAs and airspeeds
throughout the maneuver.
