ICAO Aircraft Type Designators

The FAA plans to switch all flight plans–VFR and IFR–to the ICAO format on June 5, 2017.

I’ve offered help on the most vexing problem for most pilots–the myriad codes for communications, navigation, and transponder equipment–here at BruceAir.

But long-time U.S. pilots also need to understand and use the proper ICAO type designators for the aircraft they fly. Most codes use four-characters; some use only three letters.

Some of the codes are the same as those used on the FAA domestic flight plan form, but many are different–sometimes surprising so.

For example, the ICAO designator for the Cessna 172 is C172.

But the ICAO designator for a fixed-gear turbocharged Cessna 182 is C82S.

Note that the ICAO designators don’t include hypens or other special characters. For example, the Beechcraft Debonair is BE33, not BE-33.

The easiest way to check the type designators for the aircraft you fly is via the web-based tool at the ICAO website, here. The flexible search feature quickly displays the designators assigned to aircraft by manufacturer, make-model name, and so forth.

You can also find the correct type designators in FAA order JO 7360.1B.
