737 good to know Flashcards
Conditions for aborted engine start
No N1 rotation
No EGT increase 15 seconds after start lever moved to IDLE
Little or no increase in N1 or N2 after EGT starts to increase
EGT quickly approaches or goes above the start limit line
No oil indication by engine idle
As the airplane crosses the runway threshold it should be:
- airspeed within + 10 knots until arresting descent rate at flare
- on a stabilized flight path using normal maneuvering
- normal landing in the touchdown zone (the first 3,000 feet or first third of the runway, whichever is less).

Cruise- Use FMC recommended thrust settings. If the FMC is inoperative, refer to the Unreliable Airspeed.
Descent- 76 Mach/280/250 knots. below 15,000, airplane less than the maximum landing weight, may be slowed to 250 knots in the clean configuration.
Engine start limitations
- Multiple consecutive start attempts are permitted. Each start attempt is limited to 2 minutes of starter usage.
- A minimum of 10 seconds is needed between start attempts.
Rejected takeoff up to 80knt
- activation of the master caution system
- system failure(s)
- unusual noise or vibration
- tire failure
- abnormally slow acceleration
- takeoff configuration warning
- if a side window opens
- fire or fire warning
- engine failure
- predictive windshear warning
- if the airplane is unsafe or unable to fly
Meaning of declaring “Minimum fuel”
informs ATC that all planned airport options have been reduced to a specific airport of intended landing and any change to the existing clearance may result in landing with less than planned final reserve fuel.
This is not an emergency situation but an indication that an emergency situation is possible should any additional delay occur.
Fuel leak is suspected, and cannot be explained due to prevailing winds, longer routing, actual level flown, ZFW etc.:
Flight time of up to 6 hrs: when 10% or more of the contingency fuel is consumed without an apparent reason (300 kg for 737 aircraft).
Separation on departure behind J or H aircraft
Departing from the same position: 2min behind H aircraft & 3min behind J aircraft.
Departing from an intermediate point on the same runway: 3min behind H aircraft and 4min behind J aircraft.
