Cambridge GPS-NAV Aero Explorer error on log download
I have a Cambridge GPS-NAV. I am trying to download a flight log. It looks like the Aero Explorer software is reading it from the GPS-NAV ok, but then a dialog box pops up with an error msg "Error writing flight log to disk."
I was able to download logs earlier this year, but was running on a different PC with Windows 7 (I think). I now am using a machine with Windows 8.1. I did try turning off the Avast antivirus software with no luck. I was able to download the log via SeeYou but I wanted to download it via the Cambridge software for use as an official flight for badge purposes. Any ideas on what to try other than finding a PC with an older version of Windows? (Or upgrading my logger?) |

No requirement to use Cambridge software. Check the dates, many old recorders will show a date 18 years in the past, invalidating the log. Submit to OLC as an easy check for IGC security being valid. Get rid of Windows 8.1, it was a disaster. M$ tried to upgrade everyone to 10. But using obsolete software and hardware with modern OS's leads to lots of problems. Update to something like an LXNAV Nano, which acts like a USB memory device and lets you just copy the file out easily. Trying to use RS-232 devices in this day and age is a waste of time. -Dave Any ideas on what to try other than finding a PC with an older version of Windows? (Or upgrading my logger?) |

If you still want to use the GPS-NAV with CAE, out of a sense of nostalgia, or whatever, the file write errors you are getting could be due to the workspace not being valid. Make sure it references a valid file location. You can PM me if you wish further support. Guy Byars |

This saved me when the RS-232 link from my CAI 302 into my Tophat computer stopped working at a camp this year. The GPS-NAV puts out a binary .cai file, which is secure but proprietary. Has to be converted to .igc with an external program. Definitely time to move on. -Dave Any ideas on what to try other than finding a PC with an older version of Windows? (Or upgrading my logger?) |

Cambridge GPS-NAV Aero Explorer error on log download
I was very disappointed to see that I would have to pay a bounty to get
igc logging with my PF Portable.Â* Thankfully, both my ClearNav II and ClearNav XC varios generate an igc file and it's much easier to retrieve than from the PF.

Yeah I hate that pricing model, you pay for something, then pay again if
you actually want to use it. I had to pay for both igc secure logging and ENL to use with the motorglider. PF does give you a non-secure file by default though, which can be used with their range-checking software. That's nice to show how much better range the Core gives than a Portable :-) -Dave On 07/13/2018 08:39 AM, Dan Marotta wrote: I was very disappointed to see that I would have to pay a bounty to get igc logging with my PF Portable.Â* Thankfully, both my ClearNav II and ClearNav XC varios generate an igc file and it's much easier to retrieve than from the PF.

Cambridge GPS-NAV Aero Explorer error on log download
Thanks Kinsell for this and prior comment.
I guess I didn't notice (or forgot) that SeeYou produces a .cai file also. I am assuming thoug that logs from the GPS-NAV would need to be submitted in .cai format. When I look at the flight in both igc and cai format in SeeYou I get a 'Flight integrity: Unknown?'. But when I check the cai file back in Aero Explored it says it is valid. Thanks again. |

Could be as stupid as......
Corrupted card.....reformat on new PC (32 bit vs. 64 bit can be an issue). Failed card Different type of OS (32 bit vs. 64 bit). Yep, never liked 8.1. I use mostly XP, some on 10. |

But when I check the cai file back in Aero Explored it says it is valid. Thanks again. I haven't flown badges or records for many years, so not sure what they're doing today with a GPS-NAV. Back in the day, you submitted both the .cai and .igc files. Kinda silly, since the .cai file was the only one with real security. Anybody could generate an ersatz .igc from .cai. Try to find the DOS program VALI-CAM.exe as the best test of security. Maybe Aero Explorer just uses that, or a related .DLL. Likely does. Guy would know. Three different ways to have bad files: 1) electronic seal on GPS-NAV could be broken, likely due to dead battery internally. Or somebody changed the battery w/o keeping the unit powered up. 2) date could be off. 3) data could be corrupt for other reasons, with bad crc Good luck. -Dave |
