Aircraft Instruments & Equipment Flashcards
The MMEL:
Established by the manufacturer
Approved by the authority in the state of design
Specifies which items are permitted unserviceable at the start of flight
Basis for MEL
The MEL:
Established by the operator
No less restrictive than MMEL
Approved by the authority
Permits operation with listed items unserviceable at commencement of flight
Commencement of flight:
When the aircraft first moves under its own power for the purpose of of preparing for take-off
Inoperative means?
Not consistently:
Accomplishing intended purpose
Functioning with design limits or tolerances
Rectification intervals - excluding the day of logging the defect:
Category A - Time specified in remarks column
Category B - 3 calendars days
Category C - 10 calendars days
Category D - 120 calendars days
Failures between commencement of flight and start of take-off
Command judgement and airmanship following review of MEL
No despatch with unserviceabilities unless:
Listen in MEL and listed conditions met to
Authority approves operation with the constraints of the MMEL
Flight crew must:
Check all defects against MEL prior to despatch
Ensure listed conditions are met
Refer to MEL to inform decision if defect occurs after despatch
Commander is sole authority whether defect acceptable for flight:
MEL cannot account for all combinations of multiple defects
