Question

The PIC will not operate within ______ NM of volcanic ash.

A) 5
B) 10
C) 15
D) 20

Answer 1

The correct avoidance distance from volcanic ash for aircraft is 50 NM, which is not listed in the provided options. It appears the question may contain an error or be a trick question, as the options (5, 10, 15, 20 NM) are all incorrect.

Step-by-step explanation:

The Pilot in Command (PIC) is advised not to operate within a certain proximity of volcanic ash because of the numerous hazards associated with ash clouds, such as damage to the aircraft's engines, abrasion of the forward-facing surfaces, and contamination of vital systems. These hazards can cause significant risks to flight safety. The question pertains to the avoidance distance to maintain from volcanic ash. In aviation, the standard avoidance distance from volcanic ash for which a PIC must not operate is 50 nautical miles (NM). However, the options provided in the question (5, 10, 15, 20 NM) do not include the correct avoidance distance. The intention seems to be to gauge knowledge of aviation safety protocols related to volcanic ash, but it might be a trick question or based on outdated information.
