Possible to make the beacon light stop after engines have stopped and start short time before engines start ??
Last night watched Easy Jet A319 and a Easy Jet A320 taxi in beside me and their beacons were still going an hour later.
On starting at airport both those had their beacons going even tho they were not due to take off for over another hour.
Safety first, beacons warn ground crew when the aircraft is live and ready to move or when off safe to approach aircraft.
