SECTION 5. TRAINING PROCEDURES
1 MANUAL MODE
Manual mode may be enabled for practice purposes by following the instructions for "FADEC FAILURE" described in the Emergency Procedures.
2 TRAINING MODE
Training mode can be used to practice One Engine Inoperative (OEI) flight without the risk of encountering low RPM.
| TRAIN SEL | - Open guard and ON |
| ENG MAIN | - IDLE (engine on which to simulate failure) |
While in training mode, CAD will display TRAINING for both systems and TRAIN IDLE for the system with simulated failure. Both engines will operate normally, but torque indications will be as if one engine were failed. A warning gong will sound if OEI limits are exceeded.
Recovery:
| ENG MAIN | - Both to FLIGHT |
| TRAIN SEL | - OFF and close guard |
3 PRACTICE AUTOROTATIONS
The recommended minimum altitude for practice autorotations is 500 feet AGL. Recommended procedures are as follows:
- Set up a stabilized constant altitude approach to the runway at 500 feet AGL, then just before crossing the runway threshold, lower collective and apply right pedal as necessary to maintain coordination. For a runway that starts at a sim edge, you can set up the autorotation before crossing the sim boundary. Optionally, you may set the engine controls to IDLE after establishing the descent.
- Maintain a forward speed of 50-60 knots during the descent. This speed can be adjusted up or down slightly in order to land at a specific spot, but should be within this target range before entering the flare.
- At approximately 30 to 50 feet AGL, begin a cyclic flare by pulling back on the cyclic.
- At approximately 10 feet AGL, level the helicopter with cyclic, and begin pulling up on the collective to cushion the landing.
Timing of the flare and collective input is critical. Pulling too late will result in a hard landing.
4 PRACTICE HOVERING AUTOROTATIONS
Practice hovering autorotations from a medium height hover. The apply the following procedures:
- Switch engine controls to IDLE
- Apply immediate right pedal to hold heading and maintain collective until helicopter begins to sink
- Apply full up collective as helicopter begins to sink
- Lower collective once helicopter is fully on the ground
The goal should be to set down softly with little or no change in direction.
