On the 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

An open bleed air valve during the start sequence prevents the engine from reaching the required pressure ratio for ignition. The control system logic inhibits the start sequence to protect the turbine from potential flameouts or thermal damage, ensuring the engine is properly configured for the Brayton cycle initiation.
