Checklist Instructions

Question 1

when “Confirm” needed?

Answer 1

During an inflight non-normal situation, verbal confirmation is required for:
• an autothrottle arm switch
• an engine thrust lever
• a fuel control switch
• an engine or APU fire switch, or a cargo fire arm switch
• a generator drive disconnect switch

This does not apply to the Dual Eng Fail/Stall checklist.

Question 2

what are the situations where the flight crew must land at the nearest suitable airport?

Answer 2

These situations include, but are not limited to, conditions where:
• the non–normal checklist includes the item “Plan to land at the nearest suitable airport.”
• fire or smoke continues.
• only two AC power sources remain (two main engine generators, or one main engine generator and both APU generators).
• any other situation determined by the flight crew to have a significant
adverse effect on safety if the flight is continued.

Question 3

what does the checklist instructs for the loss of an engine indication or automatic display of the secondary engine indications?

Answer 3

There are no non–normal checklists for the loss of an engine indication or automatic display of the secondary engine indications.
Automatic display of secondary engine parameters due to engine oil quantity or vibration is for crew awareness and does not require pilot action.
Continue normal engine operation unless an EICAS alert message shows or a limit is exceeded.

Question 4

Guidelines for fire/smoke situations:

Answer 4

It must be stressed that for smoke that continues or a fire that cannot be positively confirmed to be completely extinguished, the earliest possible descent, landing, and evacuation must be done.

If a smoke, fire or fumes situation becomes uncontrollable, the flight crew should consider an immediate landing. Immediate landing implies immediate diversion to a runway.
However, in a severe situation, the flight crew should consider an overweight landing, a tailwind landing, an off-airport landing, or a ditching.
