The term LAND/DITCH IMMEDIATELY is defined as:

executing a landing or ditching without delay due to the seriousness of the malfunction. The primary consideration is to assure the survival of occupants of the aircraft.

WARNING
The potential loss of the airframe after aircrew egress is not sufficient cause to continue flight.

2

The term LAND AS SOON AS POSSIBLE is defined as:

executing a landing at the first site at which a safe landing can be made. The primary consideration is the urgency of the emergency.

3

The term LAND AS SOON AS PRACTICABLE means:

extended flight is not recommended. The landing site and duration of flight is at the discretion of the Pilot-in-Command.

4

The term ABORT MISSION means

that the aircraft shall not proceed on its assigned mission and should return to its desired recovery base.

5

When speaking in terms of circuit breakers, CHECK means:

Note status of affected circuit breaker (out or in). No further action necessary.

6

When speaking in terms of circuit breakers, CHECK/RESET means:

Ensure that affected circuit breaker is in. If affected circuit breaker is popped, attempt to reset circuit breaker once.

7

When speaking in terms of circuit breakers, CYCLE means:

Pull affected circuit breaker, wait 15 seconds, and reset circuit breaker.

8

When speaking in terms of circuit breakers, PULL means:
