You are preparing your small unmanned aircraft system (sUAS) for a night operation under Part 107 and need to inspect it in low ambient light. To best preserve your night vision during this preflight activity, which type of illumination should you use?

A remote pilot in command (PIC) feels fatigued after limited sleep and has taken an over-the-counter cold medication that lists drowsiness as a side effect. According to fitness for flight considerations, what should the PIC do before conducting the sUAS operation?

During a time-critical small UAS operation inspecting a tall structure, the remote pilot becomes anxious after a close avoidance of an obstacle. The pilot notices rapid breathing, lightheadedness, and tingling in the fingers. What is the BEST immediate action?

A remote pilot is flying a small unmanned aircraft system (sUAS) over a large, featureless open field during daylight hours. The pilot reports difficulty maintaining a sharp focus on the sUAS when it is hovering approximately 500 feet away, even though flight controls indicate a stable hover. Which physiological factor affecting vision is most likely contributing to this issue?

A remote pilot in command (PIC) finished consuming alcoholic beverages at 11:00 p.m. the previous evening. The PIC intends to conduct a small unmanned aircraft system (sUAS) operation at 6:00 a.m. the next morning. According to 14 CFR part 107, is the PIC prohibited from operating the sUAS?

After completing several hours of continuous sUAS operations on a demanding project with tight deadlines, a remote pilot notices symptoms of fatigue including frequent yawning, difficulty concentrating on the video feed, and slowed responses to control inputs. The most appropriate action to ensure safety is to

A remote pilot in command consumes an alcoholic beverage at 1200. The remote PIC plans to conduct a small UAS operation at 1900 the same day. According to FAA regulations, may the remote pilot act as PIC?

Fitness for flight requires a remote pilot in command (PIC) to self-assess for potential impairments due to

A remote pilot under high stress during a time-critical small UAS operation begins hyperventilating. Which of the following best explains the primary physiological mechanism impairing the pilot's cognitive performance?

A remote pilot is studying a chart of the human dark adaptation curve, which illustrates the recovery of visual sensitivity after exposure to bright light during preparation for a night UAS operation. According to the chart, approximately how long is required for full rod (scotopic) adaptation to achieve maximum night vision capability?

A remote pilot is scheduled to conduct a time-sensitive small UAS inspection after a stressful morning commute and only four hours of sleep the previous night. The pilot feels fatigued upon arrival. What is the MOST APPROPRIATE action?

A remote pilot is conducting extended small UAS operations in warm, humid conditions. Midway through the flights, the pilot experiences symptoms including fatigue, dizziness, dry mouth, and slightly impaired concentration. The pilot took an over-the-counter antihistamine for seasonal allergies earlier in the day. What is the most appropriate response considering the pilot's fitness for flight?
