What are Air Traffic Control Height limit maxima ?
In our area, because of the proximity of a major airport, and the general trend to `squash’ ever more aircraft into the airspace, helicopters are not permitted to fly at a height greater than 1500 feet above sea level. If you already live on a hill – for example some parts of our County are 350 feet above sea level – then in our region the maximum height above your chimney is only 1150 feet.
