Remote Pilot (Part 107) practice question 43
When preparing for a night flight, what should an sUAS pilot be aware of after assembling and conducting a preflight of an aircraft while using a bright flashlight or work light?
Show answer
Correct answer: B. It takes approximately 30 minutes for a persons eyes to fully adapt to darkness.
Full dark adaptation takes about 30 minutes, and a moment of bright light can undo it. Use dim or red light after preflighting under bright light.
