Night currency and the three definitions of night that trip up every pilot
The FAA defines 'night' three different ways—civil twilight, one hour after sunset, and sunset to sunrise—each triggering different rules pilots must follow.
The FAA uses three separate definitions of “night,” each applying in a different regulatory context. Sunset to sunrise governs position light requirements. End of evening civil twilight to beginning of morning civil twilight (roughly 30 minutes after sunset) defines night for logging flight time. One hour after sunset to one hour before sunrise sets the window requiring night passenger currency. Confusing these definitions can mean flying illegally without realizing it.
Why Does the FAA Have Three Definitions of Night?
Each definition serves a distinct regulatory purpose, and they’re scattered across different sections of Title 14 of the Code of Federal Regulations.
Definition 1 — FAR 1.1 (General Definition): Night is the time between the end of evening civil twilight and the beginning of morning civil twilight. Civil twilight occurs when the center of the sun is six degrees below the horizon—roughly 30 minutes after sunset and 30 minutes before sunrise, though this varies by latitude and season.
Definition 2 — FAR 61.57(b) (Passenger Currency): To carry passengers at night, you must have completed three takeoffs and three full-stop landings in the preceding 90 days, during the period from one hour after sunset to one hour before sunrise.
Definition 3 — FAR 91.209 (Position Lights): Aircraft position lights must be on from sunset to sunrise. This is the broadest window of the three.
The result is three different “start times” for night, each triggering a different requirement.
When Do I Need My Position Lights On?
FAR 91.209 requires lighted position lights from sunset to sunrise. This kicks in before either of the other two definitions of night. Between sunset and the end of civil twilight (roughly a 30-minute window), your position lights must be on even though you are not yet flying “at night” for logging purposes.
How Does Night Passenger Currency Work Under FAR 61.57(b)?
To legally carry passengers at night, you need three takeoffs and three full-stop landings within the preceding 90 days, performed during the period from one hour after sunset to one hour before sunrise.
Key details that trip pilots up:
- Full-stop landings only. Touch-and-goes count for daytime currency under FAR 61.57(a), but the night provision in paragraph (b) specifically requires full-stop landings. The FAA wants you to have practiced the complete landing sequence—rollout, taxi, the whole process—in darkness.
- Same category and class. Your night landings must be in the same category and class of aircraft in which you plan to carry passengers. Three night landings in a multi-engine airplane do not make you night-current in a single-engine airplane.
- Tailwheel consideration. If you fly tailwheel aircraft, your recent full-stop night landings must also be in a tailwheel airplane, per the landing currency requirements of FAR 61.57 combined with the tailwheel endorsement requirements of FAR 61.31(i).
What Can I Legally Do in the “Gray Zone” Between Sunset and One Hour After?
This is where understanding the distinctions pays off. Consider this scenario: the sun set 45 minutes ago, and a friend wants you to fly to a nearby airport for dinner.
At 45 minutes past sunset, you’ve likely passed civil twilight, meaning you’re flying “at night” for logging purposes. But you haven’t reached the one-hour-after-sunset mark, so the night passenger currency requirement hasn’t kicked in yet. Even if your night currency has lapsed, you could legally carry a passenger during this window—provided you land before the one-hour mark.
That said, planning a flight around a razor-thin regulatory margin is poor aeronautical decision-making. Understanding the rule is important; relying on it as your safety buffer is not.
How Should I Log Night Flight Time?
Night flight time for your logbook uses the FAR 1.1 civil twilight definition: end of evening civil twilight to beginning of morning civil twilight, per FAR 61.51(b).
When logging night landings for currency, be precise. Record the date, time, and explicitly note full-stop landings. Your logbook is your evidence of currency, and on a checkride you may be asked to analyze a scenario and determine whether a pilot is legally current.
How Do I Stay Night Current Without It Becoming a Burden?
Ninety days passes quickly if you’re not flying at night regularly. Build night currency into your routine:
- Every two to three months, go out after dark and shoot a few full-stop landings.
- Don’t wait until someone invites you to fly at night and then scramble to determine if you’re current.
- Log meticulously. Date, time, full-stop notation. If you ever face a ramp check or checkride scenario, your logbook is your defense.
A Scenario Worth Thinking Through
You’re a private pilot who completed three full-stop night landings on January 15. A friend invites you to fly to a breakfast fly-in on April 16, departing at 5:30 AM. Sunrise is at 6:45 AM.
Ninety days from January 15 is April 15, so on April 16 your night currency has expired. But one hour before sunrise (6:45 AM) is 5:45 AM. Between 5:30 and 5:45, you’re technically outside the night currency window—meaning you could legally depart with your passenger during that 15-minute window.
But should you? A 15-minute margin leaves no room for delays. If the flight runs long and you’re still airborne after 5:45, you’re carrying a passenger without night currency. The regulations set a minimum standard. Good judgment demands you exceed it.
What Night Training Do Student and Private Pilots Need?
Student pilots need a specific endorsement from their instructor to fly solo at night. For the private pilot certificate, FAR 61.109 requires a minimum of:
- 3 hours of night flight training
- A cross-country flight of over 100 nautical miles total distance
- 10 takeoffs and 10 full-stop landings at an airport with an operating control tower
These are minimums. More night training is always better, because the transition from day to night flying introduces real risk changes: reduced depth perception, fewer visual references, and increased susceptibility to spatial disorientation.
Key Takeaways
- The FAA defines night three ways: sunset to sunrise (position lights), civil twilight to civil twilight (logging), and one hour after sunset to one hour before sunrise (passenger currency).
- Night passenger currency requires three full-stop landings in 90 days—touch-and-goes do not count, and the landings must be in the same category and class of aircraft.
- The “gray zone” between sunset and one hour after is a period where you may legally carry passengers without night currency, but planning around this narrow window is risky.
- Log night landings precisely with date, time, and full-stop notation to maintain clear proof of currency.
- Build night currency into your routine every few months rather than scrambling to verify legality when a night flight opportunity arises.
