Q

Shut down procedures for a hot start/ anticipated hot start

A

1 Throttle off
2 monitor FTIT
3. If FTIT remains above 500° c or if another start is to be made, motor engine with JFS until FTIT is below 200° Celsius not to exceed 4 minutes, or for a minimum of 30 seconds before initiation of another start
