- Max ΔP 8.65 PSID ; safety relief 8.50 ± 0.15 ; min duct pressu 18 PSI.Max ΔP 8.65 PSID; safety relief 8.50 ± 0.15; min duct press for pressurization 18 PSI.
- Isolation AUTO = OR packs OFF / bleeds OFF (switches, pas valves).Isolation AUTO = OR packs OFF / bleeds OFF (switches, not valves).
- CPCS AUTO FAIL ≠ DCPCS (bus AC vs DC, seuils rate/altitude).CPCS AUTO FAIL ≠ DCPCS (AC vs DC bus, rate/altitude thresholds).
- STBY malfunc non indiqué ; TFR BUS 2 perdu → MAN DC.STBY malfunction not indicated; TFR BUS 2 lost → MAN DC.
- BLEED TRIP : Pack OFF, pas forcément Bleed OFF.BLEED TRIP: Pack OFF, not necessarily Bleed OFF.
- WING-BODY : aucune valve auto ; TRIP RESET inutile.WING-BODY: no auto valve; TRIP RESET useless.
- Un pack → HIGH flaps UP ; dispatch MEL 21-01 = FL250.One pack → HIGH flaps UP; dispatch MEL 21-01 = FL250.
- Rule of thumb : 10k ft → pointeurs 1 et 4 ; descent NM ≈ cabin ALT/100.Rule of thumb: 10k ft → needles 1 and 4; descent NM ≈ cabin ALT/100.
- Fuel unpress 10 000 ft ≈ 10 × distance.Fuel at unpressurized 10,000 ft ≈ 10 × distance.
- PASS OXYGEN → Timer ; DIFF PRESS > 4 PSI pour juger « under control ».PASS OXYGEN → Timer; DIFF PRESS > 4 PSI to judge “under control”.
