| If, during the starting cycle, the gas turbine starter is manually disengaged immediately after light-off | nothing will happen, since this situation cannot occur due to the automatic disengagement of the starter at the proper time |
| a good practice when removing an ignition lead is to | wait a predetermined amount of time for the electrical charge to dissipate and ground the lead to the engine case |
| What does QECA stand for | quick engine change assembly |
