1T-6A-1 T-6A Flight Manual: Section 3: Emergency Procedures Flashcards
Abort Start Procedure (3-3)
In the AUTO start mode, the PMU should terminate the start sequence if
a no start is detected or if a hung or hot start is projected.
- no start
- hung start
- hot start
Abort Start Procedure (3-3)
In the AUTO start mode, if a no start is detected or if a hung or hot start is projected, the PMU should terminate the start sequence. However, the engine start should be aborted manually in the following situations.
- ITT rate of increase appears likely to exceed 1000 degree C (hot start)
- ITT appears likely to remain between 871-1000 Degree C for >5 seconds.
- Normal N1 increase is halted (hung start)
- No rise of ITT is evident within 10 seconds after fuel flow indications (no start)
- BAT BUS annunciator illuminates during the start sequence
- PCL is moved or the ST READY annunciator extinguishes during the start sequence
