Sometimes I see a negative distance display when using the the ABEAM FIX function... As I get closer to the fix, the readout changes to positive values.http://members.ozemail.com.au/~b744er/737/...veCountdown.jpgCheers.Ian.

There seem to be some kind of distance miscalculation. It can be seen not just with with this feature but also on TOD calculations (which sometimes shows greater distance than actual destination) leading to eroneous 'insufficiant fuel' message.Like you say, at some point, closer to the fix or destination the calculations become correct again.Maybe this issue is adressed in SU2, in any case I don't find it to be a major issue, perhaps a small annoyance.//Mike
