Petersburg, AK (PSG/PAPG)

Petersburg James a Johnson Airport

Airport Environment

The Petersburg James A Johnson Airport is located on the north end of Mitkof Island about halfway between Juneau and Ketchikan, Alaska. The runway runs primarily east-west and is only accessible from a channel with mountainous terrain on each side. With terrain precluding the development of a traditional straight-in instrument approach, it makes Petersburg a challenging location without the right procedures. The current public approaches to Runway 23 provide circling only minima and are offset 65 degrees to the runway. There are no public procedures for Runway 5.

NavShare Offering

New RNAV guided procedures with straight-in line of minima have been developed for Petersburg. These are specially designed for Petersburg’s unique environment to increase access to the airport during inclement weather conditions. The procedures utilize satellite-based guidance with WAAS technology to provide precise navigation to and from the runway environment. For properly equipped aircraft, these RNAV approaches allow for significantly lower approach minimums and better runway alignment when compared to public procedures. A new RNAV guided departure procedure has been developed and is available.
