Hello friends, sorry to bother you.
I have trouble understand why my most beloved flight mode, Cruise, is crashing for me.
As soon as I enter it the throttle goes to 0% and after some 20 secs time the plane stalls.
I can’t understand what in my parameters make this happen - Can you?
In this log there are 3 times I enter Flight mode Cruise - all with same result, I hade to bail out before a stall, the air speed gets too low.
I would never have guessed!
Turned off terrain following and disabled altogether the terrain function, and now the cruise mode works just like it’s expected to.
I don’t need it on this plane.
It’s not really new I think but rather these settings were copied over from a similar plane I use in Europe.
Mmm strange.
The cut off altitude is set very high like 250m I think, so it will not try to soar below that. The altitude I engage Cruise is around 100m.
I’ve never tried to use terrain following, so I’m just relating what I can find in the wiki.
Since (I believe) cruise mode was the only one set up to use terrain following, it made sense to try disabling that, but I don’t see anything in the log to indicate that terrain data was unavailable.
Perhaps the problem is with the F405 FC; perhaps it has less ram and flash than the FC in your working vehicle?
Thanks a lot guys for your effort and great inputs.
Lots of resonable reasons why this is happening. @kd0aij @Lano @LupusTheCanine
Unfortunately, I don’t have time to dig deeper but just happy to have the Cruise mode resurrected to normal glory.
However, if anyone feel these findings are a concern to how the software is working, please let me know and I will be happy to carry out some test, as per your requests.
