If the flight time is less than 2.5 hours the cabin

altitude is controlled to 8.000 ft. at Fl 410.

If the flight time is more than 2.5 hours the cabin

altitude is controlled to 7.350 ft. at Fl 410.

The schedule uses time and flight level data

(from the FMGES) to adapt the rate of pressure

change in the fuselage to the scheduled cruise

altitude.
