Loiter Procedures Flashcards

1
Q

Brief

A

Conduct as soon as engine is shut down

Crew, Engine no. 1 is shutdown for loiter. If we have a malfunction on an operating engine requiring immediate shutdown, we will shutdown the applicable engine and complete the emergency shutdown checklist through ALTERNATE HRD. After which we will restart engine number 1 beginning with PCO. If we have a deferred emergency and elect to restart number 1 first, flight engineer, I will call for you to PCO and restart number 1. Once you call normal restart, we will take corrective action on the malfunction.

Pre-shutdown considerations

A

NATO

Normal Gen 2 and 3
All buses energized
Top 3, bottom 3 gauges working
OAT (Should not be used when visible moisture is present and ambient temperature is below 10C because of possible buildup of ice - without moisture, loiter should not be conducted below 0C unless necessary, then time table should be followed)
