An equipment suffix provides controllers with information about your navigation capability. ATC will use this information when assigning routes, departure procedures, arrivals, and approaches so it is important to include the correct equipment suffix when filing your flight plan. Always file an equipment suffix representing the highest capability of your aircraft, even if you plan not to use that capability during the flight.
If you would like to find your equipment type suffix automatically, use our Equipment Type Suffix Selector. Otherwise, please use the information in the tables below to pick the correct equipment type suffix to file with your aircraft type.
Please see this post on our forums for more information about getting Current Navigation Data for your aircraft
