If compass is bad, position hold or RTL can result in "get as fast as possible 
away from it" even "go in opposite direction"..

Logic: 
If AP decides to go "north" to get to desired direction, and distance to home 
does not decrease - verify that heading is correct  - change heading (big 
circle) until most effective way home is detected. (highest velocity to home) - 
compensate or "don't get confused" while doing so by stick input if any during 
this maneuver.
