On marine gas turbine engine panel shown in the illustration, which of the following conditions would prevent the auto start sequence from successfully completing? Illustration GT-0016

Correct Answer: Option B — Bleed air valve open

The auto-start sequence includes interlocks to prevent damage during ignition. A bleed air valve remaining open during start could cause an improper air-fuel ratio or compressor instability. Consequently, the control system logic inhibits the start sequence until the valve is confirmed in the closed position for safe operation.
