FAA Commercial Pilot Airplane (CAX)Human Factors and ADMEasy
During preflight planning, a commercial pilot uses the IMSAFE checklist. What is the primary purpose of this checklist?
- ATo verify the airplane's weight and balance is within limits
- BTo evaluate whether the destination airport has adequate runway length
- CTo determine if the airplane's fuel reserves meet regulatory minimums
- DTo assess the pilot's personal fitness to fly before each flight
Show answer & explanationAnswer & explanation
Correct answer: D. To assess the pilot's personal fitness to fly before each flight
IMSAFE (Illness, Medication, Stress, Alcohol, Fatigue, Emotion) is a personal self-assessment checklist pilots use to evaluate their own physical and mental readiness to fly safely.
Why the other options are wrong
- A. Weight and balance is assessed separately, not part of IMSAFE.
- B. Runway length is an airport performance consideration, unrelated to IMSAFE.
- C. Fuel planning is an aircraft/flight planning consideration, not personal fitness.

Memory trick: I'M SAFE to fly only if I check myself first
