What is the required cooldown delay between cranking attempts?

• A. One Minute
• B. Two Minutes
• C. Three Minutes
• D. Five Minutes

Answer: (B)

Two minutes between cranking attempts. This cooldown gives the starter and start system time to shed the heat generated during the previous start, protecting the starter motor, electrical circuits, and related components from overheating. It also allows the engine’s lubricants and fluids to stabilize before the next attempt, improving the likelihood of a successful light-off. If the engine doesn’t start within the allotted start cycle, you wait two minutes before trying again, and you follow any additional limits in the aircraft procedures. Shorter delays risk overheating; longer delays aren’t typically required for normal starts, so two minutes is the standard.
