The allowed values are derived from ICAO ECCAIRS Aviation / 1.3.0.12 / Data Definition Standard

• "Fixed wing"
  A fixed wing aircraft is a heavier than air aircraft with wings which remained in a fixed position under given conditions of flight. May include variable geometry aircraft.
• "Helicopter"
  A helicopter is a heavier-than-air aircraft supported in flight chiefly by the reactions of the air on one or more power driven rotors on substantially vertical axes.
  
• "Dirigible"
  A power-driven lighter-than-air aircraft.
  
• "Gyroplane"
  A gyroplane heavier-than-air aircraft supported in flight by the reactions of the air on one or more rotors which rotate freely on substantially vertical axes, formerly known as "autogyro".
  
• "Balloon"
  A non-power-driven lighter-than-air aircraft. For the purposes of ICAO Annex 1, this definition applies to free balloons.
  
• "Microlight"
  May also be called "ultra-light". The definitions vary from State to State.
  One definition in ICAO documentation reads: an aircraft having a maximum take-off mass not exceeding 454 kg. (1 000 lbs) which is not usually used for public transport purposes. (ICAO Doc 9626, 1996, 1st ed., p. 5.2-2) More specifically, a Microlight is an aeroplane having no more than two seats, Vs,, not exceeding 35 knots (65 KM/h) CAS, and a maximum take-off mass of no more than:
  • 300 kg for a landplane, single seater; or
  • 330 kg for an amphibian or floatplane, single seater; or
  • 495 kg for an amphibian or floatplane, two-seater, provided that a microlight capable of operating as both a floatplane and a landplane falls below both MTOM limits, as appropriate.
  • 450 kg for a landplane, two-seater.
  • Foot-launched aircraft are excluded from this definition.
• "Glider"
  Sailplane or Glider means a heavier-than-air aircraft that is supported in flight by the dynamic reaction of the air against its fixed lifting surfaces, the free flight of which does not depend on an engine.
  
• "Other"
  e.g.:Ornithopter. A heavier-than-air aircraft supported in flight chiefly by the reactions of the air on planes to which a flapping motion is imparted.
  
• "Unknown"
