When planning a mission and setting the speed between waypoints, I'd like enable the Pixhawk to automatically set max speed so as to maintain altitude. (Well heck, also when I am NOT flying a mission.)
In other words, if I call for 15m/s and the hex can not maintain altitude at that speed, the Pixhawk will automatically dial back the speed to 14 or 13 (or whatever) so as to maintain altitude.
Is there a parameter that says "limit speed to maintain altitude"?
I'd think this would be particularly useful toward the end of a long flight when voltage may be dropping...I'd really like Pixhawk to automatically sacrifice speed for altitude so as to not descend into terrain.
