In order to get a ready indication for a normal start with an GE LM2500 gas turbine engine, what permissive(s) must be met?

Correct Answer: Option D — All of the above.

A normal start sequence for the GE LM2500 requires specific safety interlocks. The bleed air valve must be closed to ensure proper airflow, the gas generator speed must be below the threshold to prevent hot starts, and all engine trips must be reset to confirm the system is ready for operation.
