T-34C OUT-OF-CONTROL FLIGHT
General: This maneuver will emphasize to the IUT the need for shadowing the
controls and ensuring the student enters and removes rudder in a smooth manner
while executing HAPL, LAPL, or Precautionary Emergency Landing (PEL)
procedures. The aircraft will depart controlled flight due to a rapid increase in yaw
rate. Figure 1-4 illustrates this departure is not due to yaw angle, but the rate at which
yaw is achieved. Remember, this departure is only demonstrated in one manner, but
could occur under varying circumstance, (i.e., the student changing directions while
completing S-turns or bow-ties and changing or removing rudders too quickly.
This maneuver is demonstration only and will not be performed by
The maneuver will be flown and recovered by the Standardization Instructor. In the power off
glide configuration, aircraft will be clean. The maneuver may be performed in either direction.
Minimum entry altitude for the maneuver will be 8000 feet AGL.
Configuration: Position the aircraft at a minimum of 8000 feet AGL in slow
cruise and clean configuration.
Perform Checklist and Clearing turn.
Roll wings level, then reduce the PCL to 205 ft-lbs. and slow to 100-knot glide
Enter skid (simulating an accidental misapplication of rudder by a student).
Once established in the skid, swap to the other rudder quickly with little or no
back stick to emphasize depart due to yaw rate.
Recover using OCF Procedures.
The procedures outlined in this FTI have been gleaned from the experiences and misfortunes of
others. Training methods listed herein have been thoroughly tested through years of flight
experience with the T-34C aircraft and have proven the ability to expand the skill envelope of
each new IUT. Every T-34C IUT is encouraged to read and live by the procedures outlined in
NATOPS and this FTI. Your first experience in the aircraft will demonstrate it is a very docile
aircraft in the OCF scenario. This is very true, but in the hands of an unprepared pilot, it is very
