Ch. 9 - Emergency Procedures (BASIC) Flashcards
Land Without Delay
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.
Land As Soon As Possible
A landing at the nearest suitable landing area (i.e. an open field) without delay. The primary consideration is to ensure the survival of the occupants.
Land As Soon As Practicable
A landing at a suitable landing area. The primary consideration is the urgency of the emergency.
Autorotate (definition)
Adjusting the flight controls as necessary to establish an autorotational descent and landing.
