AH-64D Chapter 9 Emergency Procedures

Land Without Delay

The term LAND WITHOUT DELAY is defined as a landing in which the primary consideration is continued control of the aircraft and survival of the occupants. It is meant to be more urgent than Land As Soon As Possible. The situation may not permit the aircre

Land as Soon as Possible

The term LAND AS SOON AS POSSIBLE is defined as landing at the nearest suitable landing area (e.g., open field) without delay. The
primary consideration is to ensure the survival of occupants.
