Malfunctions during powerplant start, procedures to address the malfunction, and any associated limitations.
Bottom line
An engine tendency to exceed maximum starting temperature limits is termed a hot start. A condition where the engine is accelerating more slowly than normal is termed a hung start or false start. During this time, the pilot should watch for any tendency of the temperatures to exceed limitations and be prepared to cut off fuel to the engine.
Key numbers
| Number | What it means |
|---|---|
| 2 or 3 seconds after fuel is introduced for temperatures to approach maximum before the engine stabilizes | Temp rise |
| a very few seconds of over temperature before serious damage | Overtemp limit |
