AirMap is also another great app. It gives not only the airports and heliports within 5 miles, it also gives the phone numbers to contact them. Chances are in a city, you'll have many heliports listed within 5 miles.One week as an owner of a MP and am ready to take it out of the burbs and into the big city- Chicago. Can anyone tell me what rules/Regis exist when flying in a big city like Chicago? Thanks.
