Before flying at an unfamiliar high-elevation location, what is a prudent performance check?
- A.Assume sea-level performance applies everywhere
- B.Rely on the aircraft's altitude readout to judge power margin
- C.Review the manual for altitude limits and make a short, conservative test flight first
Correct answer
C. Review the manual for altitude limits and make a short, conservative test flight first
Why
Elevation changes density altitude and therefore power margin. Checking the manufacturer's altitude guidance and validating behavior with a brief, low-risk flight prevents surprises on a longer mission.
