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).

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.
Stabilized approach
1000ft AFE in IMC or 500ft AFE in VMC.

- sink rate is no greater than 1,000 fpm unless briefed.
- ILS: LOC&GS one dote or LOC expended scale.
- Circling: wing level by 300ft AFE.
- At 100 feet HAT,flight deck is within, and tracking to remain within, the lateral confines of the runway edges extended.
Mandatory missed approach
- a navigation radio or flight instrument failure occurs which affects the ability to safely complete the approach
- the navigation instruments show significant disagreement
- ILS final approach and either LOC or GS shows full deflection.
- on an RNP approach alert message indicates ANP exceeds RNP.
- NPS Airplanes , anytime NPS deviation exceeds the limit or an amber deviation alert occurs and the crew is unable to change to a non-RNP procedure
- Non NPS airplanes, anytime the XTK exceeds 1.0 X RNP and the crew is unable to change to a non-RNP procedure.

engine for maintenance action
