T-6B PRIMARY INSTRUMENT NAVIGATION CHAPTER FIVE<br />
508. BACKUP FLIGHT INSTRUMENT (BFI) FLIGHT<br />
General. Maneuver the aircraft by means of the backup flight instrument.<br />
Description. Backup flight instrument flight begins upon failure of the primary attitude<br />
instrument, the PFD. The flight must now be continued and the aircraft attitude controlled by<br />
referring to the remaining instruments.<br />
Procedure. For partial panel training, after noting a red X over the upper half of the PFD or<br />
when directed:<br />
1. Smoothly level the wings with coordinated rudder and aileron and reposition the nose to<br />
the straight and level flight attitude by use of the BFI.<br />
2. Complete the NATOPS emergency procedures as required.<br />
Common Errors.<br />
Over correcting or rushing into the emergency procedures prior to trimming the aircraft to<br />
straight and level flight.<br />
509. GCA MANEUVER<br />
The GCA maneuver closely resembles the procedures used for an instrument Ground Controlled<br />
Approach (GCA).<br />
Procedure.<br />
1. The GCA maneuver is begun at 200 KIAS, clean, on a cardinal heading and base altitude to<br />
simulate the radar downwind.<br />
2. Make a SRT in either direction for 90º of heading change while maintaining altitude. Lead<br />
the rollout using the one-third rule.<br />
3. Slow towards 150 KIAS by reducing power to 10-25% torque. With the power reduction,<br />
slight rudder / rudder trim will be required. Nose up trim will also be required in order to<br />
maintain altitude. Stabilize at 150 KIAS, power as required.<br />
4. Make a SRT in the same direction as the previous turn for 90º of heading change. Again,<br />
lead the rollout using the one-third rule.<br />
5. While maintaining heading and altitude, make a level transition to the Basic Approach<br />
Configuration (BAC):<br />
a. Reducing power to 10-25% torque, add slight left rudder pressure and trim to<br />
compensate for the power reduction.<br />
