30.6.2 Principle explained
In traditional flying, knowing the relative position of the helicopter to the pilot (transmitter)
is crucial as stick input (except for throttle) directly affects the course. That is, if the
helicopter’s nose faces the pilot and they apply aileron, elevator, or rudder, behaviour is
essentially reversed. In case of loss of orientation the pilot may inadvertently crash the
helicopter.
When active, I.R.P.C solves this problem by registering the »NovaX 350’s take-off position
on motor start. All stick input is translated relatively to the take-off position, regardless of the
»NovaX 350’s position in flight. In other words, if the pilot takes off with the »NovaX 350’s
nose facing away from them, stick input always will affect the course relative to the take-off
position. [ Fig. 18 ] illustrates this priciple based on a mode 2 transmitter.
Mode 2
A - Take-off position B - I.R.P.C. On
Mode 2
Fig. 18
[ Fig. 18 ] :
[A] denotes the take-off position and [B] the behaviour when I.R.P.C. is on. In [B] the
»NovaX 350 has been turned by 180° and moves to the right when aileron is applied,
whereas in traditional flying it would move to the left. This is because all input is translated
relatively to the take-off position (
[A] ).
