Drone Pilot Practice Exam

To maintain visual line of sight, what can a remote pilot use?

1. Telescopes

2. Binoculars

3. Contact lenses

4. Smart glasses

The correct answer is: Contact lenses

Maintaining visual line of sight (VLOS) is a crucial requirement for remote pilots operating drones, as it involves being able to see the drone at all times to ensure safe flight. The correct answer indicates that contact lenses can assist in achieving VLOS by correcting the pilot's vision, allowing them to see the drone clearly without obstruction. When a pilot wears contact lenses, they can eliminate any visual impairments, ensuring that they can maintain awareness of the drone's position and surroundings from a distance. This is particularly important as remote pilots must be able to visually monitor the drone's flight path and any obstacles or other aircraft in the area. Other options may provide visual assistance in different contexts, but they do not adhere to the practical requirements for maintaining VLOS. For example, telescopes and binoculars, while enhancing vision, can actually limit the pilot's ability to maintain VLOS since they direct focus at a specific object and can prevent the pilot from having a comprehensive view of the surroundings. Smart glasses may also offer augmented reality features, but they do not directly enhance the pilot's ability to see the drone without obstructing their general line of sight. Hence, using contact lenses enables remote pilots to properly fulfill the VLOS requirement effectively.
