lrargerich replied to lrargerich's topic in Little Navmap | Little Navconnect | Little Logbook Support ForumThanks for the details. May I wonder which distance formula is being used? The one I have is: (Acos((Sin((([PROFILE:A_GPS_PREV_LAT] * 3.1415926535 / 180))) * Sin((([SIMCONNECT:GPS POSITION LAT] * 3.1415926535 / 180)))) + (Cos((([PROFILE:A_GPS_PREV_LAT] * 3.1415926535 / 180))) * Cos((([SIMCONNECT:GPS POSITION LAT] * 3.1415926535 / 180)))) * (Cos((([SIMCONNECT:GPS POSITION LON] * 3.1415926535 / 180)) - (([PROFILE:A_GPS_PREV_LON] * 3.1415926535 / 180))))) * 6378) But this one is giving me a flown distance greater than LittleNavMap, I know there are other Great circle distances but not sure which one is the one you used.

lrargerich replied to lrargerich's topic in Little Navmap | Little Navconnect | Little Logbook Support ForumThanks Alex, May I ask how you get the aircraft position via Simconnect? (I guess). And if you update the trails every time these vars are being updated? My guess is to take the LAT and LON from Simconnect and compute the geodesic distance every time those change but I'm getting different results than LittleNavMap so I wonder what I'm doing wrong.

Sorry for this curious question. I'm trying to use SPAD to compute the total distance flown and I know Little Navmap already does it so I wonder if it uses Simconnect variables, then I would be able to replicate that with SPAD. Thanks! Lu.
