Night Fly Time

When may a remote pilot extinguish the anti-collision lights of a small unmanned aircraft during flight operations at night?

• Anti-collision lights may not be extinguished during any night flight operations.

• If the remote pilot in command determines that, because of operating conditions, it would be in the interest of safety to do so.

• When flying over a populated area with well-lit ground features.

As landing an sUAS at night is particularly challenging, select a landing area: [Source: FAA-H-8083-24, Small Unmanned Aircraft Systems Operating Handbook]

• That is as far from crewmembers as possible

• With sufficient lighting to allow a safe landing

• Over water, sand, or other soft surface

If the Remote PIC cannot determine the location of the sUAS in relation to other aircraft during night operations, when should he or she land the sUAS? [Source: FAA-H-8083-24, Small Unmanned Aircraft Systems Operating Handbook]

• At the end of the planned operation

• immediately

• Within 10 minutes

When does the Remote Pilot in Command operating at night have the discretion to reduce the intensity of the anti-collision lighting?

• In the interest of operational safety.

• Never

• Only at the start of a night operation

According to 14 CFR part 107, what is required to operate a small unmanned aircraft in civil twlight or at night?

• Selection of a rural area for conducting the operation

• Use of lighted anti-collision lights

• Use of a transponder

What additional step should you take at night when preparing for an sUAS flight?

• Check for sources of ground lighting and ensure that the lights will not be turned on during the flight.

• Use glasses with side blinders to block peripheral light that may impair depth perception.

• Use the sUAS built-in obstacle detection and avoidance technology if you no longer can determine its location relative to another aircraft.

When may a remote pilot reduce the intensity of an aircraft’s lights during a night flight?

• At no time may the lights of an sUAS be reduced in intensity at night.

• When a manned aircraft is in the vicinity of the sUAS.

• When it is in the interest of safety to dim the aircraft's lights.

At night, where will you likely experience a blind spot in your vision?

• Throughout the entire field of vision.

• In the center of your field of vision.

• Only in your peripheral vision.

Under what circumstances may a Remote PIC reduce the intensity of the lights of an sUAS when operating at night?

• If the light has caused the remote pilot to lose the ability to observe the small unmanned aircraft’s location.

• The lights may be reduced temporarily if they interfere with the primary mission of the flight operation.

• The PIC may reduce the intensity as a consideration to others.

You plan on conducting a flight with your small unmanned aircraft at night. Upon powering on the sUAS, you notice that the anti-collision lights are not functioning, but the navigation lights are functioning. Is this flight legal to conduct?

• No, the anti-collision lights must be operational.

• Yes, if the navigation lights are functioning and anti-collision lights are deferred in the maintenance logbook, you may conduct the flight legally.

• Yes, the navigation lights are functioning and provide visibility.
