CHAPTER 1Interpretative matter
Meaning of “in flight”3
An aircraft is deemed to be in flight—
a
in the case of a piloted flying machine, from the moment when, after the embarkation of its crew for the purpose of taking off, it first moves under its own power, until the moment when it next comes to rest after landing;
b
in the case of a pilotless flying machine, or a glider, from the moment when it first moves for the purpose of taking off, until the moment when it next comes to rest after landing;
c
in the case of an airship, from the moment when it first becomes detached from the surface until the moment when it next becomes attached to the surface or comes to rest on the surface;
d
in the case of a free balloon, from the moment when the balloon, including the canopy and basket, becomes separated from the surface until the moment it next comes to rest on the surface; and
e
in the case of a captive balloon, from the moment when the balloon, including the canopy and basket, becomes separated from the surface, apart from a restraining device attaching it to the surface, until the moment when it next comes to rest on the surface,
and the expressions “a flight” and “to fly” are to be construed accordingly.
