May 31/13 – Niagara Falls restricted flight area CYR 518 demystified.
Due to the restricted airspace around the Falls all aircraft must climb to 3500 ASL ft prior to entering the circuit. The circuit can be entered from SW (50) or NW (100) directions. The boundaries of this restricted space start at the Welland river on the south side and at the QEW highway so if you are flying in the area make sure that you have 3500 ft ASL before you cross these landmarks.
