- Stagnation of N1/N2
- EGT creeping up slowly
- N2 increases very slowly or stops increasing at approx. 7% N1 / 34% N2 with increasing EGT
- Low Fuel Flow
- Low Duct Pressure
- Strong tailwind during start
- Note N1, N2 (stall less than 40%), FF, DUCT PRESS & EGT; EGT may rise above 300degC and Hot Start occurs
- Abort start; FCS to cutoff (by recall)
- Start Timer
- Call for "ABORTED ENGINE START" Checklist
- Inform GND and ATC
- If N2 continues to increase and engine stablises within two minutes, the following EGT are acceptable during slow start:
- >> N2 40%, EGT(slow) 370-390, EGT(norm) approx. 200
- >> N2 50%, EGT(slow) 425-440, EGT(norm) approx. 300
- >> N2 60%, EGT(slow) <500,>
Circuit Breaker(s):
- NO
- NO
If engine restart required:
- Select IGNITERS to Both
- When N2 0% (Reset EEC)
- Restart affected engine
- Return IGNITER to 1 or 2
- Slow in aborting the start
- Not noting down engine parameters for maintenance info
- Not selecting IGNITERS to both for subsequent start
- Not waiting for N2 to spool to 0%
- Not returning IGNITER to original position after a restart
