Airport Flare M76 is used to indicate the end of a runway in a fog.
This flare consists of a cylinder containing a candle similar to — but larger than — the candle of the Flare AN-M26. The cylinder is fitted with a socket base arrangement into which four channel-shaped legs may be inserted to hold the flare upright on the runway.
The flare may be initiated by the use of the electric squib or by pull on the release fork which allows the spring-loaded firing pin to strike the primer. The primer acts directly to ignite the first fire composition.
