Operations & SafetyQuestion 98 of 100

On the morning of a job, an RPIC takes an over-the-counter antihistamine whose label warns that it may cause drowsiness. What does Part 107 require?

a.Fly only if a visual observer is present to watch the aircraft
b.Do not act as RPIC while the medication would affect safe operation
c.Fly only during the first 30 minutes after taking the dose, then land
d.Obtain a medical certificate from an aviation medical examiner first

Explanation

Section 107.17 prohibits acting as RPIC, VO, or direct participant when you know or have reason to know of a physical or mental condition — including the effects of medication — that would interfere with safe operation. Adding a VO does not cure the pilot's own impairment, and there is no rule that legalizes flying inside a short window after a dose. Part 107 requires no medical certificate at all, so option d states a requirement that does not exist.
