Practise Operational Procedures
In accordance with Air OPS, for a pressurised aeroplane, the minimum requirement for supplemental oxygen needed to supply 100 % of the passengers following a cabin pressurisation failure, is:
What is the purpose of supplemental oxygen after loss of cabin pressurisation?
In a discretised minimum-time isochrone calculation, a trial air-relative displacement is calculated for a time step Δt starting from the preceding ground isochrone. For wind that may vary along the trial segment, which displacement must be added to obtain the ground displacement?
An uncompensated, locally level directional gyro is aligned with north on a Greenwich-parallel northern polar grid at 14:00 UTC at 59°57′N 010°30′E. The aeroplane remains stationary until 16:30 UTC, with no mechanical drift and no gyro reset. Using an Earth rotation rate of 15°/h, what is the gyro-heading error, defined as indicated heading minus actual grid heading, to the nearest 0.1°?
In the standard mean-latitude approximation, let G be the longitude change expressed as an angle, Lm the mean latitude and Lo the chart’s parallel of origin. Which expression gives the transport-wander angle of a locally level gyro?
According to NOAA’s World Magnetic Model criteria, below which horizontal magnetic-field intensity H are locations within either the weak-field Caution Zone or the Blackout Zone?
After any required immediate safety actions for a defect detected while parked, which operator-specific document determines whether an item listed in it may remain inoperative for dispatch and under what conditions?
The holdover time of an aircraft’s ground anti-icing treatment has been exceeded before take-off. Under the operator’s approved procedures, what action is required?
According to the UK CAA long-grass policy guidance, which of these habitat-management approaches can reduce attraction to hazardous birds when suitable for local species and conditions?
Under AMC1 ATS.TR.260(g), in VMC, which condition prevents a runway being selected for landing specifically for noise-abatement purposes?
