ABSTRACT:
The invention concerns a starting system for a gas turbine aircraft engine which automatically controls the sequencing of events needed during engine startup. The control schedules fuel in a manner which avoids stalls, and, further, takes corrective actions when stalls occur, both on the ground and in the air. The control detects failures in the starter energy source, which can cause an abortive start and damaging temperatures. The control also provides unique scheduling of fuel in severely cold conditions.
