FAA 107 Physiological Effects & Pilot Fitness

Question 1

Under FAA Part 107, what is the minimum waiting period after consuming alcohol before acting as remote pilot in command?

Accepted Answer

8 hours

Answer

FAR 107.27 prohibits acting as remote PIC within 8 hours after consuming any alcoholic beverage, commonly known as the 'bottle to throttle' rule.

Question 2

What is the maximum blood alcohol concentration (BAC) allowed for a remote pilot in command under FAA Part 107?

Accepted Answer

0.04%

Answer

FAR 107.27 sets the BAC limit at 0.04 percent, which is lower than the typical 0.08 percent legal driving limit.

Question 3

A remote pilot legally uses marijuana in a state that has legalized it. Under FAA Part 107, which statement is correct?

Accepted Answer

They may never act as remote PIC because marijuana remains federally illegal

Answer

FAA regulations are federal law, and marijuana remains a Schedule I controlled substance federally, so state legality is irrelevant to FAA Part 107 compliance.

Question 4

Which over-the-counter medication is MOST likely to impair a remote pilot's ability to safely operate a UAS?

Accepted Answer

Diphenhydramine (Benadryl)

Answer

Diphenhydramine is a first-generation antihistamine that causes significant drowsiness and impairs reaction time, making it dangerous for drone operations.

Question 5

Under FAA Part 107, a remote pilot who is taking a prescription medication should:

Accepted Answer

Consult a physician or AME about whether the medication affects the ability to fly safely

Answer

The remote pilot is responsible for self-certification of fitness, so consulting a physician about medication effects on judgment and reaction time is the correct approach.
