Problem: Ground Speed Estimate with Volkslogger and WinPilot
I noticed the same problem with my winpilot/VL, although I don't think it has
anything to do with VL, since the ground speed is correct in the NAV box, but incorrect only in the final glide display. I reported this problem to Jerry last year, not sure if it was fixed in later releases. Ramy Is anyone else seeing the WinPilot/Volkslogger problem I am seeing? Running WinPilot v3.019 Adv on an IPAQ 3635. GPS data is from a Volkslogger. The GPS signal is also fed to a Cambridge LNAV. Everything works fine except the WinPilot function to estimate task completion time based on ground speed. This function is found on the final glide display page (touching the chevrons on the left side of the map, then pressing the MC button to let finish time computation use the ground speed. The WinPilot estimate of ground speed shown is something like 18-20 mph, instead of 50mph+ actual. My NMEA mask for the Volkslogger is - - X X X - - - - Inspection of the NEMA sentances my Volkslogger is putting out all look ok (short example below). GPGGA (fix data), GPRMC (speed data), and GPRMB (track data) are all present. Anyone else have this function working correctly with a Volkslogger feeding WinPilot?
