Lights on so they see you coming? Suggests BossEyed...
Now there's a good idea! ! ! and not just for avoiding birds.
At Wellesbourne, while waiting for an engineer to check out my PA18, it was a glomy day. Typical November in the UK. I was visiting the tower, observing the locals in a busy busy circuit.
And how many aircraft in the circuit had their lights on?
Only one. The rest emerged from the gloom without warning. Is there a rule in this country says don't worry about saving lives....mustn't wear out the battery!
