RTH Settings "RTH Home altitude" prevents Autoland from finishing
If value other than 0 is entered into "RTH Home altitude" the LANDING is initiated but never gets to Landing State 1 (prevents Landing and craft just loiters)
GitHub description says... nav_rth_home_altitude Aircraft will climb/descend to this altitude after reaching home if landing is not enabled. Set to 0 to stay at nav_rth_altitude (default) [cm]
This may be true for other than autoland but prevents craft from doing the autoland.
Suggest adding warning in the ?-help documentation on the iNav Configurator UI
nav_rth_home_altitude is the altitude before landing. It will RTH to that altitude, then initiate the landing sequence.
It'll stay there if you disable landing with nav_rth_allow_landing = false
Please attach a diff of your settings.
Also FYI since this is a question about INAV, rather than Configurator, it really should be in the INAV repo. No biggie though.
Thanks much for the response.
I may have found the problem - when I experienced the "glitch" I may have had the following set like so... Land Alt = 5m Initial altitude of the glide phase = 2m Initial altitude of the flare phase = 1 m ...so the FC didn't like the glide phase starting lower than the Land At ? When I set them as follows it landed well (see diag below).... Land Alt = 1m Initial altitude of the glide phase = 4m Initial altitude of the flare phase = 2m
please check the diff - do you see any problems that might affect autoland? I have been trying to get the FW to land in a shorter distance due to a power line that is about 300 m from the takeoff point. Right after I posted the GitHub issue I read online that the Land Alt is very important. Are there any other rules to observe when setting the Land Alt? For instance...should it be set to Alt=0 (zero) when not using the Above Sea Level Alt?

Sorry-forgot the Diff file! I removed all WPs (so we don't collide LOL)

BTW-found another issue that causes iNav to not enter Land State 1 (it just loiters) - its when the fwapproach 's (seen in CLI by typing "fwapproach") get out-of-whack somehow (probably thru many saves in Mission screen with different values). I overwrote all 16 fwapproach 's with zeroes and resaved the mission in Mission Control and the flight was perfect.
