You should be able to set your RTH higher than 50m if needed. But setting that aside, all heights are relative to the take off point. So if you fly to top of mountain that's 1500-253=1247 feet above take off point. It's always best to fly home under your control, but if you were to use RTH then it would stay at 1247 feet as that is above the 50m altitude you set, all relative to take off point. If you flew 100m from take off and were at an altitude of 20m (65ft) and pushed RTH it would then climb another 30m to take it to the 50m above take off point, and then it would fly straight back before landing.
In that scenario, the drone would be at a heck of a height relative to home point when it got "home" if returning under RTH command. Would that not infringe Max Height (relative to ground) regulations? In France it's 150 metres in many places, and just 50 metres or even as little as 30 metres in many others. |
