SECTION 7. EMERGENCY PROCEDURES

1 General

This section describes the most common helicopter emergencies that may be encountered in the H-160, and the appropriate actions to address those emergencies.

2 Definitions

The following terms apply for this section:

  1. The term LAND IMMEDIATELY is defined as a landing without hesitation to any landing surface. Survival of the occupants is considered the highest priority.
  2. The term LAND AS SOON AS POSSIBLE is defined as a landing to the nearest suitable landing surface. Survival of the occupants is considered the highest priority.
  3. The term LAND AS SOON AS PRACTICAL means land at the nearest suitable airfield or heliport.
  4. The term AUTOROTATE means adjusting the controls to establish an autorotation and landing. This generally means thrust control full down, then adjust as necessary to maintain 100% rotor RPM.

3 Emergency Checklists

  2. Engine Control - IDLE
    1. Wait for #1 N1 to reach 75%
    2. Abort attempt if 75% not reached after 45 seconds
  3. Engine Guard - CLOSED
  4. Engine Control - FLY
  5. N1 & N2 VERIFY - 100%

3.3 Gear Failure

Failure to Extend:

  1. Suitable Landing Site - SELECT
  2. Gear Handle - UP
