How to measure height of an airplane? Say you are on the ground and want to measure the altitude of a plane that
is going over your head, what (simple) equipment can you use? They are
supposed to maintain at least 500 feet where I am but I don't believe they
actually do. Tired of endless stream of noisy planes (helicopters the worst
actually) when I'm pottering around in the garden.
I phoned the Civil Aviation Authority last year but although polite they
were pretty unhelpful. Basically said well it's up to you to make a case and
prove these things are too low. Now it looks like we're into low-flying
season again so wondering what I could do. |
