30.5 R.T.H.
In order for R.T.H. to work, wait (1 - 10 min.) until the »NovaX 350
receives a good GPS signal before taking off.
R.T.H. (Return To Home) is a failsafe feature of S.M.A.R.T. (Software Managed Auto
Return Technology) enabling the »NovaX 350 to fly back to the take-off position and is
triggered automatically or manually. If triggered manually, the pilot can deactivate it again
to take back control as soon as they see the situation under control.
For a quick introduction to R.T.H. we suggest you watch the following short clip(s):

30.5.1 Auto triggers
> Receiver loses signal (receiver failed)
> Operating outside the operating range (approx. 300 m)
> Turning the transmitter off
30.5.2 Manual trigger
> Deactivated: R.T.H switch in position 0 (or 1 respectively)
> Activated: R.T.H switch in position 1 (or 2 respectively)
30.5.3 Procedure
When triggered, returning to home follows a simple two-step procedure: the »NovaX 350
is automatically brought into a stable hover position, then returns home. Study
[ Fig. 17 ] .
30.5.4 The importance of the GPS signal
For R.T.H. to work, a good GPS signal is required at all times. The »NovaX 350 may take
up to 10 min. for GPS signal acquisition the first time you turn it on. For subsequent signal
acquisition the time may be shorter (1 to 2 min.).
Note that whenever you move the »NovaX 350 to another location, the signal acquisition
time may increase again (1 to 10 min.). Depending on the GPS signal strength, the
»NovaX 350 behaves differently. The below table summarizes all possible behaviours.
GPS signal Behaviour on triggering of R.T.H.
Good signal at take-off and when R.T.H.
is triggered
»NovaX 350 returns home.
Weak signal at take-off, but
improved signal during flight
»NovaX 350 holds its position for 5 seconds,
then descends and lands.
Signal weakens during flight »NovaX 350 descends immediately.
