Problem display bearing and track

Hi Petr.!!!

It displays uncorrect values of bearing BRGmag and track TRK. According to which meridian and magnetic variation bearing is calculated? I usually observe difference between BRGmag and actual bearing to next waypoint (if I have a long distance to next WPT ) But if I change settings to BRGtrue all values are correct.

At the beginning of the route beraing must be equal to bearing magnetic to the next waypoint according to the actual place of aircraft(beginning of the route) 317degrees magnetic, and during flight it should change according to actual place of arcraft(meridian, magnetic variation) if program settings are set to magnetic heading.

TRK must be 317 degrees because we are on the flightpath ( XTK=0) At the pictures I,ve already sent (page1) XTK=2.28km right of flightpath it is uncritical if DME is 520km.

Hi,
can you write here example with the coordinates, so I can try the same situation.

HI!!!
UOOO
LAT 69:18.66119
LON 87:19.91821
Variattion 18.55

UODD
LAT 73:31.06796
LON 80:22.74307
Variattion 30.05

Thanks, I will check it out...

I think the problem is because threre is a big difference between variation of UOOO and UODD. I will think how to solve it.

[barneo66]

Well!
BUT TRK SHOULD NOT DEPEND ON THIS.

Problem is, that FIF use variation of next WPT not at present position. I will work on it. Next upgrade...

[barneo66]

Ok!
Thank you !
Waiting for update.

Can you try version 16.61? I hope it is solved
