What's Wrong With OLC?

[Dan Marotta]

My flight on April 25 comes back with a zero score and I can't see why.Â*
I have two recorders on board and got the same results with both.Â* I
uploaded the igc file to Skylines.aero and the flight was instantly scored.

I use OLC to support the local club, of which I'm not a member.Â* I use
Skylines because it's quicker, has a much better interface, allows me to
select my desired units, and has no advertising.Â* And, since my logbooks
have been kept in imperial units (flame suit on) for 45 years, I don't
want to mess with metric conversions to maintain my logs.Â* Maybe
everyone should switch to Skylines.aero <https://skylines.aero>...

OBTW, my OLC claim showed the same ground track as Skylines.aero, just
no points.

OLC is the de facto tool, the only place where you can see most XC flights, at least in the US.
But if you want an excellent electronic logbook and advanced interface and online analysis tool, try crosscountry.aero.
I’ve been using it for the last 5+ years as my only logbook.

Thanks Ramy, I'll give it a look.

Following someone's advice, I uploaded a flight recorded on my wife's
Streak/XCSoar.Â* It loaded perfectly so I guess the problem is either
with my ClearNav computer AND the ClearNav XC vario or with their
antennae whose cables I cut to length.Â* Today in installed new antennae
and was surprised at how quickly the GPSs locked on.Â* Maybe I'll get to
fly tomorrow and see if that was the fix.

Looks like IGCDroid may actually be usable for recording motorglider
flights on OLC. Haven't flown with it yet, but a test drive was
accepted by OLC as a motorglider. Just make sure it has permission to
record audio.

I looked up your flight on OLC and d/l'ed the igc file. The file shows up in SeeYou as invalid, which most likely means it was corrupted sometime after you d/l'ed from your flight recorder. Guessing the offending bit is a B record with a corrupted time. Try d/l'ing again and see if you get a valid result in SeeYou.

[Dan Marotta]

It shouldn't come to that, but thanks.Â* ClearNav people are looking at
the problem.

Someone pointed out the odd time display on my recent flights.Â* The same
flight recorded on a streak (and uploaded using a non-motor glider)
loaded perfectly so I think the problem is somewhere within the ClearNav
system.Â* Both the computer and the vario show the same anomaly.Â* Maybe
I'll get to fly with the new antennae today...

Thanks Evan, but I don't have SeeYou.Â* Watch this be something really
stupid like my two separate USB sticks (one for each device) have given
up the ghost in the same manner.Â* I can also try a different USB stick
next time I fly.

Could be a bad stick......
I am from the age of, "Whoa.....a 30mb USB stick.....you know how many 3.5" floppies this replaces!!!!"
First field job.....user PC was Windows NT.....no Frikkin USB support.........sigh........

Today, big USB sticks are like cheap butane lighters......the stick is cheap (make sure to format in correct OS/software) so when not sure, recycle and buy new......

[Dan Marotta]

LOL...Â* I predate Windows; PCs and Apples, in fact.

I have separate sticks for each device.Â* It's hard to imagine that both
would fail in the same manner.

As soon as I get a chance to fly again, I'll try three different
sticks.Â* Winds are currently around 20G30 kts.Â* I don't mind landing in
that, but I see no need to take off until things settle down. Ah...Â*
Spring time in Moriarty...

Current hypothesis is that OLC isn't interpreting the 2459 => 0000z daily roll over correctly, but evidently only for CNi products.

The best place for further discussion would be the CNi forum. Thanks

Evan Ludeman

[Dan Marotta]

But that's 1800 -> 1801 local.Â* That doesn't make sense unless I'm
figuring Zulu time backwards.Â* I haven't been airborne that late in
quite a while.

See you on the CNi forum.

2359 - 0000z rollover. :)

1800 mountain time is 2400 Zulu or UTC

Good thing I'm not the guy that writes the code ;-)

Dan's flight ended 2304 per the log, so doesn't sound like any kind of
rollover problem.

Looking at your April 25 flight on SeeYou, the GPS altitude graph shows
tons of dropouts (down to 0 altitude).

This is absolutely not corruption on a USB stick, the file would show as
invalid with the CRC check if it were. It's the logger showing bad
altitude numbers, and at least one out of order time stamp.

If these problems correspond to the jamming, then not much you can do.
But I wouldn't rule out interference from inside the cockpit, maybe even
the two CN antennas mounted next to each other and interfering with each
other. Stranger things have happened.

I've just replaced the two CN antennae with new, 28 dB gain antennae
with uncut coax leads.Â* They're mounted on opposite canopy rails, at
least 3 ft apart.Â* It's gusting 25 kts at Moriarty right now and
forecast up to 40.Â* I probably won't be flying today.
