Duct overpressure / overtemperature — pas une valve coincée. OR : T > 440 °C ou P > 65 PSI. En vol : CLB-2 ou V/S 1000 fpm, cycler OFF/ON.Duct overpressure / overtemperature — not a stuck valve. OR: T > 440 °C or P > 65 PSI. In flight: CLB-2 or V/S 1000 fpm, cycle OFF/ON.
CFM : ON au TOD si prévu. Boeing : ON juste avant le givrage. SOP = autorité finale.CFM: ON at TOD if expected. Boeing: ON just before icing. SOP = final authority.
Bleu = désaccord / transit. Au ralenti bright fréquent (SOV 9e + backpressure APU) — ~30 % N1 après config anti-dual-bleed.Blue = disagree / transit. Bright at idle common (9th SOV + APU backpressure) — ~30% N1 after anti-dual-bleed config.
Dispatch valve OPEN : Bleed OFF pendant start (hot start). Six indications ON : bright→dim, duct↓, N1−0,7 %, A/T↓, FF↑, EGT↑.Dispatch valve OPEN: Bleed OFF during start (hot start). Six ON cues: bright→dim, duct↓, N1−0.7%, A/T↓, FF↑, EGT↑.
Bright bref / temp / steady / oscillant = transit / limite T / bloquée / air insuffisant. Jamais à la place du dégivrage sol. Pas avec APU bleed. Pas > FL350.Brief / temp / steady / oscillating bright = transit / T limit / stuck / low air. Never instead of ground de-ice. Not with APU bleed. Not > FL350.
Sans GRD TEST : taxi OK, TLA ferme, OFF au lift-off, thermique 125 °C. Avec GRD TEST : inhibé sol, GRD TEST spring, 93 °C — switch laissé ON = perte 2e segment en l’air.Without GRD TEST: taxi OK, TLA closes, OFF at lift-off, thermal 125 °C. With GRD TEST: ground inhibit, spring GRD TEST, 93 °C — switch left ON = 2nd-seg loss airborne.
WAI ON juste après TO peut invalider climb calculé. No-bleed + WTAI taxi → oscillate — retarder config jusqu’holding.WAI ON right after TO may invalidate calculated climb. No-bleed + WTAI taxi → oscillate — delay config to holding point.
Rampe 3 min ; ≥ 10 min avant TO. Fenêtres 3/4/5 sans voyant OH. PWR TEST sol déconseillé (délaminage).3-min ramp; ≥ 10 min before TO. Windows 3/4/5 have no OH light. PWR TEST on GND not recommended (delamination).
Limites FWD 63 °C / SIDE 49 °C / #3 35 °C. Quatre OVERHEAT = test switch collé.Limits FWD 63 °C / SIDE 49 °C / #3 35 °C. All four OVERHEAT = sticky test switch.
A/B OFF·ON·TAT TEST. Alternate Static non chauffé. Attention passerelle côté gauche.A/B OFF·ON·TAT TEST. Alternate Static not heated. Watch left-side jetway damage.
TEMP PROBE = chauffage seulement. Blank ≠ Ice Crystal (≈ 0 °C). FMC SAT ≠ alternate pour MEL 30-07B. NO AUTOLAND / NO RVSM.TEMP PROBE = heater only. Blank ≠ Ice Crystal (≈ 0 °C). FMC SAT ≠ alternate for MEL 30-07B. NO AUTOLAND / NO RVSM.
Non-aspirée (trou arrière) → OAT FMC toujours. Aspirée : précise sol sauf unpressurized TO.Unaspirated (rear hole) → always manual FMC OAT. Aspirated: accurate on GND except unpressurized TO.
