Use of GPS
Use of GPS
Best Practice – Use of GPS
- Only use a GPS as a back-up to conventional chart navigation.
- Do not use a GPS to “fly the line” of controlled airspace as a small navigational error or distraction can lead to an infringement and in some airspace commercial traffic can be less than three nautical miles inside the boundary.
- Ensure that GPS maps are up-to-date.
- Learn how to operate airspace warning elements of a GPS where fitted.
- Consider using a GPS-based airspace warning tool as a navigational back-up.
Cost – None if equipment already owned. Variable cost of new equipment according to functionality required
Pilot reports from infringement incidents in the UK show that GPS can cause airspace infringements, as well as prevent them by providing accurate navigational guidance. The UK CAA has produced a DVD on the correct use of GPS, showing the problems that can occur with GPS data, and EUROCONTROL has a guide to GPS use on Skybrary. Both can be accessed through the Airspace Infringement Toolkit. NATS, the main UK ANSP, has also endorsed a simple GPS –based airspace warning device called AWARE that is proving to be a useful tool to avoid airspace infringement.
