Avoiding Helicopters
Last week I was doing a few circuits to practice my landings and was advised to keep an eye out for a helicopter hovering on the extended runway centreline (It looked like a police helicopter). It wasn't in my way at all as I was turning to stay in the circuit well before it, but it got me thinking about safe distances from helicopters. Is there a rule about how close you can get, and can you fly underneath? (I know most people may say why would you fly underneath, and I agree that I can't see any situation where I would, but, should the situation ever arise, how far below would you consider to be safe?)
