A Day in the Life — Start → Thrust → Cruise → Reverse → Shutdown Timeline
A synthesis: it strings the engine operations of 00–33 into a single "day in the life" timeline, each step citing the earlier article verbatim, with no new fact. This is how a pilot actually uses the engine across one sector.
1. The operation timeline
pre-start → start → taxi-out → take-off → climb → cruise → descent/approach → landing → taxi-in → shutdown
2. Phase by phase
| Phase | Engine operation | Source article |
|---|---|---|
| Pre-start | (if needed) FADEC GND PWR ground test; check ENG SD | 15 / 11 (GND PWR 5 min) |
| Start | ENG START → IGN/START (ENG SD appears, pack valves close, 30 s window) → ENG MASTER → ON (LP opens → start valve opens → ignition N3 25–30 % → HP opens → N3 ≥ 50 % start valve closes, 10 s) → residual EGT > 100 °C cranks first; monitor EGT (start limit 700 °C) / AVAIL → ENG START → NORM | 07 / 06 / 18 |
| Take-off | thrust levers TOGA (or FLX reduced), A/THR engaged; EPR control (03); monitor EGT (take-off limit 900 / red 920) | 03 / 10 |
| Climb | thrust levers CL detent (A/THR range both engines IDLE → CL) | 03 / 14 |
| Cruise | monitor EPR/N1/N3/EGT/OIL (PRESS/TEMP/QTY)/VIB; ETOPS one-engine plan | 10 / 32 |
| Descent/approach | levers toward IDLE; A/THR speed control | 03 |
| Landing | reverse: levers reverse (three conditions: FADEC + PRIM + LGCIU on-ground; < 70 % idle, > 90 % full reverse; blue 1 / yellow 2 hydraulics; reverse controlled on N1) | 09 |
| Shutdown | ENG MASTER → OFF (closes LP+HP valves + dump valve purges burner fuel) | 04 |
3. Key nodes and the three common mistakes
- Start watches N3: ignition N3 25–30 %, start valve closes N3 ≥ 50 % (07).
- Thrust by detent: TOGA/FLX take-off, CL cruise; under A/THR the levers do not move (03).
- Cruise scan: EPR/N1/N3/EGT/OIL/VIB (10); EGT threshold depends on thrust setting (23).
- Landing reverse: < 70 % idle, > 90 % full; blue 1 / yellow 2 (09).
- Shutdown: MASTER OFF + dump valve purges fuel (04).
[!warning]- The three most common mistakes in a day's operation (gathered) ① The start is watched on N3, not N1 (07); ② under A/THR the levers do not move — read the ECAM thrust, not lever position (03); ③ reverse is idle below 70 %, full only above 90 % (09).
Self-test
[!note]- Q1. The key N3 nodes in the start sequence? Ignition N3 25–30 %, start valve closes N3 ≥ 50 % (10 s); residual EGT > 100 °C cranks first.
[!note]- Q2. What engine parameters are monitored in cruise? EPR/N1/N3/EGT/OIL (PRESS/TEMP/QTY)/VIB.
[!note]- Q3. The landing-reverse and shutdown keys? Reverse < 70 % idle, > 90 % full (blue 1 / yellow 2, 09); shutdown MASTER OFF + dump valve purges fuel (04).
Key takeaways
| Point | Detail |
|---|---|
| Timeline | pre-start (GND PWR) → start (N3 25–30 ignition · ≥ 50 close valve) → take-off (TOGA/FLX) → climb (CL) → cruise (monitor + ETOPS) → landing (reverse < 70 idle · > 90 full) → shutdown (MASTER OFF + dump) |
| Three mistakes | start watches N3, A/THR levers don't move, reverse 70/90 % |
| This article | a synthesis: each step cites an earlier article verbatim, no new fact |
