Home › Part 107 Practice Tests › Aviation Weather Questions › Question 69
A METAR reports a ceiling of 400 feet AGL. Why does this severely limit a planned Part 107 flight that must also stay 500 feet below clouds?
- A.The usable altitude below the ceiling leaves essentially no legal operating room under the cloud clearance rule
- B.The ceiling has no effect as long as visibility is good
- C.The pilot may simply fly inside the cloud to gain altitude
Correct answer
A. The usable altitude below the ceiling leaves essentially no legal operating room under the cloud clearance rule
Why
With clouds beginning at 400 feet AGL, an aircraft required to remain 500 feet below them cannot climb at all. Low ceilings are therefore a practical no-go even before other hazards are considered.
