Emergency Procedures - Immediate Actions - FRCs Flashcards
Define ‘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. The situation may not not permit the crew to continue to manoeuvre the aircraft to a suitable landing area (e.g. open field). If manoeuvring to an open area is not practical, then the crew must make the decision to land in an area that will have the least amount of negative impact on crew survivability, (e.g. over dense forest, select an area with the smallest trees, in a mountainous area, choose an area with the least amount of slope).
Define ‘ Land As Soon As Possible’
A landing at the nearest suitable landing area (e.g. open field). The primary consideration is to ensure the survival of occupants.
Define ‘ Land as Soon as Practicable’
A landing at the nearest suitable landing area. The primary consideration is the urgency of the emergency.
