An entry in the ATL shall be made also for the following events:
- Aborted take-off above 80 knots for any non-technical reason (in that case it shall include the airspeed, wind, runway slope and use of reverse thrust);
- Return to Ramp due to any technical reason;
- Unscheduled landing due to any technical reason;
- Non-standard system operation (e.g.: alternate landing gear of flaps extension, use of fire switch etc.);
- Unusual landing that may require special maintenance action (e.g. hard landing, overweight landing etc.);
- Unusual in-flight event that may require special maintenance action – refer to list in the OM Part B - FCTM “Events Requiring Maintenance Inspection”;
- When ground de-icing or anti-icing was performed, an entry shall be made stating that de-icing was performed and the type of fluid applied with mixture ratio;
- When an autoland has been performed successfully. If the Autoland was not satisfactory, an entry shall be made with details of the problem.
Do not use assumed temperature reduced thrust
if conditions exist that affect braking, such as slush, snow, or ice on the runway, or if potential windshear conditions exist.

Engine fuel leak during engine start
If, during engine start, the ground crew reports a fuel leak from an
engine drain, continue to run the engine at idle for up to 5 minutes.
If the fuel leak stops during this time, no maintenance action is
needed. If the fuel leak continues after 5 minutes, shut down the
engine for maintenance action
Circuit breaker reset
• In flight, reset of is not recommended unless directed by a non-normal checklist. However, a tripped circuit breaker may be reset once, after a short cooling period (approximately 2 minutes), if in the judgment of the captain, the situation resulting from the circuit breaker trip has a significant adverse effect on safety. On the
ground, flight crew reset of a tripped circuit breaker should only be done
after maintenance has determined that it is safe to reset the circuit
breaker.
• Flight crew cycling (pulling and resetting) of a circuit breaker to clear a non-normal condition is not recommended, unless directed by a non-normal checklist.
Maximum windspeed reported for operation
Maximum windspeed for company operations is 65 kts including gusts (actual wind report by airport authority).
Cruise fuel penalties
- ISA + 10° C: 1% increase in trip fuel
- 2,000 feet above/below optimum: 1% to 2% increase in trip fuel
- 4,000 feet below optimum: 3% to 5% increase in trip fuel
- 8,000 feet below optimum: 8% to 14% increase in trip fuel
- cruise speed 0.01M above LRC: 1% to 2% increase in trip fuel.
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.
CDL NEF time limit
120 day as of the date CDL has been recorded for the first time.
Whenever time limit for CDL/NEF is derived from the MEL this time limit prevail
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).
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.

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).
