Hello guru's , I would like a little help with a Nav (or VOR) auto tune XML gauge for FS9.First on my pedestal I have : (A:Circuit general panel on, bool) (L:AUTO, bool) ! and%((@c:NearestVorCurrentFrequency,MHz) 100 * near d 100 div)%!03d!.%(100 %)%!02d!...plus a normal radio: (A:Circuit general panel on, bool)%((A:NAV1 ACTIVE FREQUENCY, MHz) abs)%!4.2f!Now for the RMI DME's one can use %((@c:NearestVorCurrentDistance,nmiles))%!4.1f!%but my problem is : the VOR needle indicators....what to use for them?At present for NAV1 I use : (L:nav1needle, bool) 0 == if{ (A:NAV1 Radial,radians) (A:Plane heading degrees gyro,radians) - pi 2 / + } els{ (A:ADF1 Radial,radians) pi 2 / - } It would be nice if something like this worked but it doesn't: C:fs9gps(A:GPS POSITION LAT, Radians) (>@c:NearestVorCurrentLatitude, Radians) (A:GPS POSITION LON, Radians) (>@c:NearestVorCurrentLongitude, Radians) 9 (>@c:NearestVorMaximumItems) 200 (>@c:NearestVorMaximumDistance, NMiles) 0 (>@c:NearestVorCurrentLine)(L:n1needle, bool) 0 == if{ (@c:NearestVorCurrent,radians) (A:Plane heading degrees gyro,radians) - pi 2 / + } els{ (A:ADF1 Radial,radians) pi 2 / - } I did find this post but could not get it to work.http://forums.avsim.net/dcboard.php?az=sho...ing_type=searchregardsEd

Thankyou PVE,I'll give it a try ...although just looking at it ..it looks like it autotunes NAV 2 and the ADF 1.What I would like to do is autotune the nav1/nav2 needles w/o tuning the normal A:NAV1/2 ACTIVE FREQUENCYBTW what does BCD16 mean :-hmmm

Hi Ed Just change the ADF line to (@c:NearestVorCurrentFrequency, Frequency BCD16) (>K:NAV1_RADIO_SET) this sets the active frequency If you want to change the stanby use (>K:NAV1_STBY_SET}. Not strong on maths but I think BCD is the hex value that FS accepts for frequencies. Maybe another boffin will comment!

Thankyou PVE, you have been a great help. It may interest some to know that by using (>@c:NearestVorCurrentLine)I can select which nearest VOR will tune in where ...for example the nearest VOR on NAV1 and the next nearest VOR on NAV 2 C:fs9gps(A:GPS POSITION LAT, Radians) (>@c:NearestVorCurrentLatitude, Radians) (A:GPS POSITION LON, Radians) (>@c:NearestVorCurrentLongitude, Radians) 2 (>@c:NearestVorMaximumItems) 200 (>@c:NearestVorMaximumDistance, NMiles) (L:Auto, bool) ! 0 (>@c:NearestVorCurrentLine) if{(@c:NearestVorCurrentFrequency, Frequency BCD16)(>K:NAV1_RADIO_SET) }(L:Auto2, bool) ! 1 (>@c:NearestVorCurrentLine) if{(@c:NearestVorCurrentFrequency, Frequency BCD16)(>K:NAV2_RADIO_SET) }regardsEd
