ICAO Aircraft identifier codes

Aircraft models are used by the official ICAO 8643 document. Following ICAO database will help you to find the aircraft type designators: http://www.icao.int/anb/ais/8643/search.cfm. 

    SHIP = Airship 
    BALL = Balloon 
    GLID = Glider - Sailplane 
    ULAC = Microlight / Ultralight aircraft 
    GYRO = Microlight / Ultralight autogyro  
    UHEL = Microlight / Ultralight helicopter  
    OLD  = Old aircraft types, not assigned in ICAO 8643 
    TUG = Tug 
    BOAT = Boat, ship or vessel 
    CAR = Car (should be used for an aircraft named Aerocar ) 
    MTRB = Motorbike 
    BUS = Bus  
    SSHP = Spaceship

Aircraft type

  1. type character
    • L=Landplane
    • A=Amphibian
    • S=Seaplane
    • H=Helicopter
    • T=Tilt wing
    • G=Gyrocopter
  2. engine count
  3. engine type
    • J=Jet
    • P=Piston
    • T=Turboprop


example for a B744: L4J

ICAO wake catagory

L=Light
M=Medium
H=Heavy

The wake turbulence category is provided on the basis of the maximum certificated take-off mass (MTOM) :
L (Light) for aircrafts upto 7000 kg / 15500 lbs
M (Medium) for aircrafts above 7000 kg / 15500 lbs upto 136000 kg / 300000 lbs
H (Heavy) for aircrafts above 136000 kg / 300000 lbs

Automatic Aircraft Equipment Codes

FSInn can set automatically only 2 type of headers and 2 types of trailers Header B/ or T/ Trailer /F or /G

the B/ or T/ is selected if ac is heavy (B/) or normal (T/), we assume all Aircraft have a basic TCAS (Inn Radar) so /T is the default The heavy flag(T/ + Heavy = B/) can be set for each aircraft in Inn Config (or retreive from Aircraft Repository) , else its based on the Heavy flag from aircraft.cfg

We assume all aircraft have GPS (so /G is the default), the /F (FMS) is set if the aircraft.cfg contains a flight_director_available=1 in autopilot

FAA equipment codes

Equipment codes may be preceded by “H/” to indicate “Heavy” aircraft, “T/” to indicate TCAS equipped, or “B/” for both Heavy and TCAS.

Examples: J2/X PA24/B H/B744/R B/C133/C

Following table indicates the suffixes:

/F Flight Management System (FMS) with DME/DME position updating
/G Global Navigation Satellite System (GNSS), including GPS or WAAS, with enroute and terminal capability.
/R Required Navigational Performance. The aircraft meets the RNP type prescribed for the route segment(s), route(s) and/or area concerned.
Reduced Vertical Separation Minimum (RVSM) Prior to conducting RVSM operations within the U.S., the operator must obtain authorization from the FAA or from the responsible authority, as appropriate.
