We wanted to share a guest post from our friends at FoxFury Lighting focused on Night UAV Flight and lighting requirements.
Introduction to Night Flight
Night flights are often some of the best any pilot can experience. The winds are usually calmer, seeing the city lights from above evokes emotions difficult to explain, and everything takes on an entirely new look. The view out the window or in the controller display is nothing short of spectacular, as even well-known sights take on a whole new look after sunset.
No matter what we might think of night flight, most RPC/Part 107 pilots (and general aviators) are well out of their element. Empirical data from various sources back this up, suggesting that many UAS operations at night end with some sort of minor incident, while a few are not so “minor.”
What is the Definition of “Night Flight”?
Night Flying is any flight that takes place 30 minutes after civil twilight, 30 minutes prior to before civil sunrise, or at any time between.
For more details on Night UAV Flight, FAA regulations, and safety flying unmanned aircraft at night, check out our handbook available on Amazon.
Flying a drone or UAV (Unmanned Aerial Vehicle) at night offers tremendous possibilities for enterprise markets and public safety. There are numerous uses with thermal and standard cameras for inspections, search and rescue, surveillance, and more. While flying at night does provide incredible real time information, there are some risks, hazards, and limitations that need to be understood and overcome. Night flight is any flight that takes place 30 minutes after the sun goes down (civil twilight) and 30 minutes before the sun rises (civil sunrise), or anytime between.
UAV Night Flight Challenges
One of the biggest night flight challenges is the inability to see potential obstacles like power lines, tree branches, and wires. Any contact with these obstacles could produce accidental and potentially catastrophic damage to the drone along with property and/or persons in the area. This challenge can be overcome by properly scouting the area in the daytime, conducting pre-flight inspections and using a spotlight to help illuminate these hazards.
Another challenge is preserving night vision. It takes 30 minutes for your eyes to fully acclimate in the dark, so accidental exposure to light pollution such as looking at your cell phone will impair flight ability for at least that long. The use of red light on the ground in the launch area allows the pilot and observers to still see while preserving their night vision. The use of red gels and sunglasses can also help prevent accidental exposure to light pollution.
UAV Night Flight Certifications
Under Part 107 (Commercial Flight), remote pilot certificates require waiver FAR 107.29 to deal with night flight operations. Here is the official language:
107.29 Daylight Operation:
- No person may operate a small unmanned aircraft system during night.
- No person may operate a small unmanned aircraft system during periods of civil twilight unless the small unmanned aircraft has lighted anti-collision lighting visible for at least 3 statute miles. The remote pilot in command may reduce the intensity of the anti-collision lighting if he or she determines that, because of operating conditions, it would be in the interest of safety to do so.
- For purposes of paragraph (b) of this section, civil twilight refers to the following:
– Except for Alaska, a period of time that begins 30 minutes before official sunrise and ends at official sunrise
– Except for Alaska, a period of time that begins at official sunset and ends 30 minutes after official sunset
– In Alaska, the period of civil twilight as defined in the Air Almanac.
The FoxFury Rugo 2 lights meets the above requirements for 107.29. In fact, they are visible from a distance of 6 statute miles. The Rugo Quick Swap Power Pack with Strobe strobes at a rate of 90 times per minute, which is within the FAA requirement of 40-100 times per minute.
Assuming you have fulfilled the above requirements, you still need to have technical proficiency to fly a drone. Flying at night is stressful and practice is important.
The pilot also needs a night waiver when flying under section 107. Waivers for night flight need to be written correctly to help the pilot get access granted.The most important thing to consider when your waiver is that you have considered all possible problems that could arise and you are prepared to deal with each every one of them.
The approval process can take days to weeks, so it is critical to get it submitted and approved on the first attempt. The majority of 107.29 waivers are rejected by the FAA for a variety of reasons, yet the greatest cause of rejected waivers falls into two categories:
- Incomplete waiver application
- Copy / pasted waiver application and explanation of various procedures

If you need anti-collision lighting or lighting for inspections that meets 107.29 requirements, using at least one of the FoxFury Rugo 2 Drone Lights with the Quick Swap Power Pack with Strobe will get the job done.
