INTRODUCTIONS AND SPINS
This Flight Training Instruction (FTI) has been written to provide aerodynamic background
information and to establish procedures for recovery from inadvertent Out-of-Control Flight
(OCF) and for intentional OCF training encountered in the T-34C. It is designed to provide
Instructors Under Training (IUT) with the fundamental knowledge needed to recognize, prevent,
and recover from aerodynamic loss of control of the aircraft.
Departure from controlled flight is practiced to familiarize the IUT with those realms of flight
that may be encountered as a result of control misapplication by an inexperienced Student Naval
Aviator (SNA). The intent is to expose the IUT to disorienting flight regimes and reinforce the
essential need for prompt and correct flight conditions analysis. For example, am I spinning?
Have I already departed controlled flight or am I just in an unusual attitude? Once you have
analyzed the flight condition, you must be prepared to affect the proper recovery procedures.

Flight at high Angles of Attack (AOA) is an inherent part of stall, spin, and aerobatic training.
The pilot's confidence, necessary to operate in these regimes effectively, is key to his ability to
analyze and recover easily from the occasional out-of-control condition associated with high
It is important to realize the AOA the pilot sees just prior to departure will vary significantly
depending upon what kind of maneuver he is performing (i.e., how much yaw rate or sideslip he
is generating). The higher the yaw rate or sideslip, the lower the indicated AOA at departure.
