can you fly without beacon light？

Yes, you can fly without a beacon light—but it depends on the type of aircraft, the time of flight, and the airspace regulations.

Here’s a breakdown:

🛩️ Fixed-Wing Aircraft and Helicopters (General Aviation)

Daytime Flights (VFR – Visual Flight Rules):

A beacon light is not strictly required during daytime operations for most small general aviation aircraft. However, other lights (like position/navigation lights) may still be required depending on the airspace and regulations.

Nighttime Flights:

Anti-collision lights (beacon or strobes) are generally required. For example:

In the U.S., under FAA regulation 14 CFR 91.209, aircraft must have an approved anti-collision light system operational for night flying.

If the beacon light is inoperative, a strobe system can be used instead, if installed.

🚁 Helicopters

Similar rules apply. Helicopters must have an anti-collision light system when flying at night or in conditions where visibility is limited.

✈️ Commercial or Transport Aircraft

These aircraft are required to have a fully functioning anti-collision light system (which typically includes beacon lights) regardless of time, especially due to stricter maintenance and airworthiness requirements.

⚠️ Summary

Day (VFR, small aircraft): Flying without a beacon light may be legal.

Night or low-visibility: A functioning anti-collision light system is required, which usually includes either a red rotating beacon or white strobes.

If your beacon is broken, a maintenance log and alternate anti-collision lights (if available) may allow you to fly temporarily under some conditions.

Always check your local aviation authority's rules (e.g., FAA, EASA, CASA) and the Minimum Equipment List (MEL) for your aircraft.
