Having constructed and equipped your machine, the
next thing is to decide upon the method of controlling
the various rudders and auxiliary planes by which the
direction and equilibrium and ascending and descending
of the machine are governed.
The operator must be in position to shift instantaneously
the position of rudders and planes, and also to control the action of
the motor. This latter is supposed to work automatically and as a
general thing does so with entire satisfaction, but there are times when
the supply of gasolene must be regulated, and similar things done.
Airship navigation calls for quick action, and for this
reason the matter of control is an important one—it is
more than important; it is vital.
