Note(s)

As far as possible, classification is made according to constructional features; classification according to particular kinds of aircraft is normally regarded as being of secondary importance, except in cases where this is considered to be the characteristic feature.  [3]

Note(s)

In this subclass, the following terms or expressions are used with the meanings indicated:

  • "installations" embraces equipment, including mobile equipment, peculiar to use in connection with aircraft and not fitted thereto;
  • "ground installations" embraces waterborne installations.  [3]

Note(s)

  1. This subclass covers only vehicles, equipment or the like, which are specially adapted for cosmonautics.
  2. This subclass does not cover vehicles and equipment applicable to both cosmonautics and aeronautics, which are covered by the appropriate aeronautical subclasses of class B64.
  3. In this subclass, the following term is used with the meaning indicated:
    • "cosmonautics" includes all transport outside the earth's atmosphere, and thus includes artificial earth satellites, and interplanetary and interstellar travel.
