It actually does solve issue 1164 (which I started).
When one switches to the next waypoint, the active leg course and x-track-error
relate to the leg between the previous and active waypoint of the flightplan
(as it should in LEG mode). Previously the leg (-course and x-track-error) was
formed between the active waypoint and the position of the aircraft at the
moment of switching.
The other stuff I asked Dirk to add as it makes our extra500 (GPSS) AP design a
lot easier.
Cheers,
Eric

Great,.
And make the overflight sequence configurable for the aircraft. The default is
the same./instrumentation/gps/config/over-flight-arm-angle-deg
90/instrumentation/gps/config/over-flight-arm-distance-nm
1/instrumentation/gps/config/over-flight-distance-nm
0over-flight-distance-nm : - distance to waypoint - overflight -> next
waypointover-flight-arm-distance-nm: - distance to waypoint
over-flight-distance-nm + over-flight-arm-distance-nm- overflight arms the cone
over-flight-arm-angle-deg : - the cone left/right from LEG pointing on the
waypoint- when armed and the aircraft leafs the cone -> next waypoint.
Great, although I do wonder if anyone will ever really adjust the cone angle.
Doesn't do any harm though.
branche fix-issue1164 @ my
clonehttps://gitorious.org/fg/dirks-flightgear/source/85592ec45db2866a15197c051d97cb4014537b4b:Who
should I ask for merge ?
Me, only query is that the above don't really seem to relate to issue 1164,
which is about initial behaviour of the GPS when entering leg mode away from
the active leg.
Are you happy for me to pull from that branch to review, or would you rather
send a patch, or make a merge request on Gitorious. All of those are fine with
me, your choice.
