What is the burn time of the MK-79 red star display?

Explanation:
The burn time of a MK-79 red star display is about 4.5 seconds. This fixed duration is built into the device to produce a bright red signal long enough for observers to notice and identify distress, without keeping the flare burning far longer than intended. Shorter times wouldn’t give enough visibility, while longer times would reflect a different design than the device provides.
