SSA-UDSC

[Moshe Braner]

On this page: https://docs.weglide.org/contests/national/ssa_udsc.html it says:

"Flights may only be documented using IGC-approved GNSS flight recorders or with position recorders approved by the SSA Contest Committee (e.g., Flarm without IGC approval, FlyWithCE)."

This is distinct from the regular WeGlide scoring - and from SSA regional competitions - which accept flight logs from additional devices, such as XCsoar running on a phone.  Is that the intention?  Why?  Many more pilots would participate if they didn't have to buy or borrow an IGC-certified flight recorder.

Also, that page says:

"The start and finish points are considered successfully passed if entry into a 1 km radius circle around the start/finish point is documented."

This is distinct from (more stringent than) the 1-km-wide start/finish line required for, e.g., USA state records.  Why?

[Moshe Braner]

Oops, I meant "less stringent".

I agree with you about the XCSoar, but that file isn't "locked".

I've flown a 422km and 359km flight and still can't get my gold distance due to some technicalities with each. 

The first one I had my silver declaration still left in my approved flight logger.

The second one was worse because while I had the task in my xc soar file, it wasn't in my approved flight logger. And I flew the pre-planned task. 

The LXNav Nano that i have no longer supports the phone app that used to use, on my previous phone. So now I'll have to get the task loaded to a micro SD card, and put into my S100 vario, which i recently got calibrated. 

Oh well, there's always next year, I guess. Regards,

Sorta branching off topic here, but I've been using XCsoar connected to my S80 connected to my powerflarm core to record flights. I was able to declare my flights on XCsoar which would declare it on the S80 then the flarm. With an S100, I think you should be able to just connect XCsoar with Bluetooth and declare the flight rather than fiddling with an SD card or trying to setup the task on the vario.

As for why the UDSC rules are different from everything else... Who doesn't like having an additional arbitrary requirement that they can complain about :D

The OGC file from XCsoar (or Tophat or IGCdroid or SoftRF...) is "locked" in the sense that it includes G-records at the end (a type of encrypted checksum of the whole file), thus if you change anything in the file it won't pass the validation test.  The only reason it is not "IGC certified" is because it was generated on hardware that is not sealed, so you could in theory have fed it fake GPS data or something.

Doesn't Naviter offer you an updated version of their app, to run on your new phone?  Or, you can still use the old app on the old phone if you still have the old phone, even if it does not have "service".  Or, do what Ryan does, set up the task in XCsoar and have it send it to the S100 and from there to the FLARM, if you have an IGC-approved FLARM.  Similarly in my glider I have Tophat (on a modified Nook) connected via serial cable to my FLARM, thus I set up the task in Tophat (easy) and it sends the declaration through that cable to the FLARM.

But I agree, if you have an Official Observer vouching as to your declaration, it shouldn't also be required to have it within the flight log, which is easy to botch.  But them's the rules.

This makes way more sense at a regional level. 

…without atc clearances in class A, night vision goggles, etc.  

Just pointing out what should be obvious.
