Which of the following is one of the five key decision points for flight?

• A. Approach
• B. Taxi
• C. Preflight
• D. Climb

Answer: (C)

The key idea here is recognizing the go/no-go decision points that frame a flight. Preflight is one of those points because it happens before you move the airplane and requires you to assess whether conditions and the aircraft are all within safe limits. During the preflight, you check weather, fuel, weight and balance, aircraft systems, and flight plan, and you decide if the flight can proceed. If any of these checks fail or show unacceptable risk, you would not fly.

Approach, taxi, and climb are important phases of flight, but they’re ongoing parts of the execution rather than the initial decision point in this framework. They involve decisions, but the framework’s recognized go/no-go point before departure is the preflight.
