Night Operations & Lighting
~10 min read · Meet the anti-collision-light rule and the training required for night flight.
Night flying went from waiver-only to rule-based in 2021, but the rule has teeth: current night training and anti-collision lighting visible for three statute miles. The exam checks the two conditions plus the physiology and twilight definitions that ride along.
The two legal conditions
Night operations (between the end of evening civil twilight and the start of morning civil twilight) are legal without a waiver if: (1) the remote PIC has completed current initial or recurrent training that covers night operations (all post-April 2021 FAA courses do), and (2) the sUAS carries lighted anti-collision lighting visible for at least 3 statute miles with a flash rate sufficient to avoid collision. The remote PIC may reduce the lighting's intensity only if it remains visible for 3 SM.
- Training: current initial/recurrent course including night subjects
- Lighting: anti-collision, 3 SM visibility, flashing/strobing
- Both conditions — training AND lighting — must be met
Twilight vs night
Civil twilight spans 30 minutes before official sunrise and 30 minutes after official sunset (longer periods in Alaska). During civil twilight, operations also require the 3-SM anti-collision lighting — but the night-training requirement technically attaches to night itself; in practice, current training covers you throughout. After civil twilight ends, you are in night, and both conditions apply in full.
- Civil twilight: sunset+30 / sunrise−30 — lighting required
- Night: after evening civil twilight ends — lighting + training
- Alaska gets its own longer twilight definition
Operating well at night
Legal is the floor. Survey the site in daylight (obstacles — wires above all — vanish at night), use off-center viewing and dark adaptation, distinguish the aircraft's orientation lights from its anti-collision strobe, keep VLOS distances shorter than daytime habits, brief crew light discipline (no white light into adapted eyes), and confirm the strobe is actually visible at mission distances — a belly-mounted strobe hidden by the airframe fails the requirement in the direction that matters.
Worked example
A pilot certificated in 2019 who has never retrained wants to shoot a city skyline at 10 p.m. His drone has bright white orientation LEDs but no strobe. Sunset was 7:40 p.m. What stands between him and a legal flight?
Three gaps. Time: 10 p.m. is well past end of evening civil twilight (~8:10 p.m.) — this is night. Training: a 2019 initial course predates the night curriculum; he must complete the current online recurrent training (which he is likely overdue for anyway under the 24-calendar-month rule). Equipment: steady orientation LEDs are not anti-collision lighting — he needs a flashing/strobing light visible 3 SM. With recurrent training completed and a compliant strobe fitted, the 10 p.m. flight is legal with no waiver. The exam wants exactly this checklist: night defined by civil twilight, training currency, 3-SM strobe.
Common exam pitfalls
Counting bright orientation LEDs as anti-collision lighting.
Anti-collision means flashing/strobing and 3-SM visible. Steady position lights don't qualify.
Flying at night on pre-2021 training.
The night privilege rides on CURRENT training that includes night subjects — recurrent training refreshes both currency and the night content.
Treating dusk as day.
Lighting is required from sunset+30 onward — and the 30-minute twilight windows are the civil twilight definition, not sunset itself.
Night needs two lights on: one on the aircraft (3 SM strobe), one in your head (current training).
Recap
- Night ops legal since 2021: current night-inclusive training + 3-SM anti-collision light
- Civil twilight = sunrise−30 / sunset+30; lighting required there too
- Strobe must flash and be visible 3 SM in the directions that matter
- Daylight site survey, dark adaptation, off-center viewing
- Shorter VLOS distances and crew light discipline at night
- No waiver needed — the conditions replaced it
