During cockpit engine starts, how many crew members must be present?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: (C)

Two crew members must be in the cockpit during engine start. Having one pilot handle the start while the other monitors parameters, warnings, and the overall sequence provides essential cross-checking and immediate response if something abnormal occurs. This crew setup supports effective communication and safe management of the start, which is considered a critical phase. Starting with no one or with only one person lacks the necessary oversight and reduces safety, while having three crew members isn’t required for a standard start.
