7.17. Unusual Attitude Recoveries.
p. 132
7.17.1. Objective. Recover to normal attitude with reference to instruments only.
p. 132
7.17.2. Description. An unusual attitude is any unexpected or inadvertent attitude encountered during normal instrument flight. Generally, in IMC conditions, bank should be limited to 30 degrees and pitch limited to 10 degrees nose low to 15 degrees nose high. Possible causes of unusual attitudes include slow cross-check, spatial disorientation, channelization on a subtask, and transition from VFR to IFR. The recovery is complete when the desired attitude for normal instrument flight is reached.
p. 132
7.17.3. Procedure. Perform recoveries as described in AFMAN 11-202V3. Use the EADI as the main recovery instrument after proper operation is verified and it is confirmed that an unusual attitude exists. Compare the EADI indication with the STBY attitude indicator and performance instruments to confirm an unusual attitude.
p. 132
7.17.3.1. If operating properly, the EADI is used to recover. The horizon bar is always visible, but in extreme nose-high or nose-low attitudes it may be very near the bottom or top of the EADI. In these cases, red recovery chevrons point to the horizon and may be used to determine attitude.
p. 133
7.17.3.2. Bank interpretation and control response are most important in recovering from unusual attitudes. In high performance aircraft, an inverted (beyond 90 degrees of bank), diving attitude is the most critical situation. Correction to an upright attitude (less than 90 degrees bank) is the priority and must be initiated before pitch correction.
p. 133
7.17.3.3. If the aircraft is diving, roll toward wings level and start pull-up when bank is less than 90 degrees. Reduce power and extend the speed brake if required.
p. 133
7.17.3.4. If the aircraft is climbing, use power as required to maintain desired airspeed and smoothly increase bank to reduce vertical lift and maintain 1G, not to exceed 90 degrees of bank. As the fuselage dot of the miniature aircraft approaches the horizon bar, adjust bank to establish a wings-level attitude. If airspeed is low, the nose may continue below the horizon. Only use as much bank as required to recover; it is not necessary to use 90 degrees in all recoveries.

7.17.4. Technique. “Recognize, Confirm, Recover”:
p. 133
7.17.4.1. Recognize - Identify potential unusual attitude with EADI and aircraft performance.
p. 133
7.17.4.2. Confirm - Verify actual attitude with standby (STBY) ADI and performance instruments.
p. 133
7.17.4.3. Recover - Apply appropriate recovery procedure.
p. 133
7.17.5. Once recovered, correct altitude and heading back to what was previously assigned. If a gross deviation has occurred outside the training airspace confess to ATC and make corrections back to assigned clearance.
