Aircraft (ICAO Definition)

Aircraft- An aircraft is any machine that can derive support in the atmosphere from the reactions of the air other than the reactions of the air against the earth’s surface. (ICAO Annex 1, Annex 6 Part I)

  1. Is a parachute or a paraglider an aircraft?

  2. It depends on where you are. In New Zealand the CAA has ruled yes. see Interpretation of CAR Part 1 – Parachute is an Aircraft at http://www.caa.govt.nz/Legal_Information/Legal_Info_003.pdf.
    A paraglider would definitely be considered an aircraft and I believe a parachute should be too considering the CAA’s reasoning.
    Also an aircraft standard is used to certify parachutes in the US.

    National Aircraft Standards Specifications Number 804 which is the minimum performance standards required by Technical Standard Order, TSO-C23b, for applies to the manufacture of parachute assemblies.

  3. Is a rocket an aircraft?

    i have come to understand that most books describe a Kite as an aircraft.I question this definition, my reason being we can design something that may identify as a kite (condition 1)Probably stick it to a pole instead of a string only difference is we are using a pole instead of a string in this case the string has higher elasticity so the kite will stay in one place more easily.(Condition 2) now remove the kite from the pole but fails to fly can it still be called an aircraft? Furthermore, the icao definition of an aircraft states that Aircraft means any machine that can derive support in the atmosphere from the reactions of the air otherwise
    than by the reactions of the air against the surface of the earth.but this definition does not justify the fact that a kite is also using mechanical support from the ground.
