We discussed this on drones-discuss a while ago. For various reasons, a 2 level battery failsafe would be useful, where level one RTLs or does whatever the user configures and level two LANDs.
For level one I could imagine e.g.
RTL
Fly to closest rally point
Fly to specified waypoint (failsafe-point)
Start beeping / flashing yellow
The main reason is that immediate LAND is not always desirable, e.g. when operating over water or over forest. A 2 level battery failsafe would give the operator the possibility to calculate and configure a battery level at which it is still safe to RTL/fly to a failsafe destination (see #1163) before LANDing.
