Question for US Rules committee on AH capability within LX NAV computers?

I've been thinking exactly the same thing!

Max! Why did you not use the special US rules icon! Please consider
updating! Its priceless!!!!!!!!!!!!! ;-)

XC Soar and LK8000 are useless mobile based, unfixed 1g gyro's on mobile phones and faced direct demands from the USRC.

LXNAV has a huge high priced capability and not a peep?

Follow the money...

I think there's a misunderstanding.

A competition-ready version of XCSoar can ascertain a lack of cloud-flying instruments to extent that a lack of the AHRS box can. You can circumvent the XCSoar/Comp restriction by installing another XCSoar version in a hidden place, by taking a second PDA, by installing it via a data-link and removing it, and so on. Similarly, you can hide your sensor box somewhere. Either variant of cheating is relatively easy to accomplish.

Such rules make it (a little) harder to cheat, but not impossible. The may or may not be in the interest of safety, and they are certainly silly in the light of the dysfunctional XCSoar horizon, but it seems that they apply to everybody and all devices. No AHRS box - no IMC instrument. No XCSoar with "horizon" - no instrument. Butterfly horizon disabled for 14 days - no instrument. And so on. Simple as that.

Sean,

You really are a prick.

Hi Sean,

I'm not sure I understand your argument. The XCSoar and LK8000 software
products (which I hear are very nice) are (if I understand correctly)
opensource products. The code is freely available.

The LXNAV LX8000, LX8080 and LX9000 are not opensource. They are products
that have firmware that is not freely available. Updates to those LXNAV
products is done by requesting a new version of the firmware from LXNAV
which is tied to a particular unit serial number. It would not be possible
for anyone other than LXNAV to make changes to those products. They have
recently implemented features in the firmware which make it easy to disable
the artificial horizon for 14 days - longer than any contest. Also, it is
easy for any contest official to look inside the glider and determine
whether or not the AHRS unit is installed and connected to the flight
computer. It connects to the flight computer using a standard USB cable.
If there is no USB cable connected to the flight computer, then the AHRS is
not connected. This is much different than the opensource software issues.

However, I strongly agree with you that it is silly and frustrating that the
rule committee has decided to restrict our technology. It discourages
innovation and discourages pilots from flying in U.S. soaring competitions.

Best Regards,

Paul Remde

With all due respect, the RC has not "decided" to restrict anything. What the RC has done is provide a way for instrument manufacturers and software developers who choose to include AH capability in their product to remain compliant with a very long standing (decades) FAI rule.

It is not an FAI Rule. Nothing to prevent the fitting or indeed use of AH
in civilised parts of the world. By all means restrict the members in your
own country if that is your wish but accept that it is totally your
responsibility not the FAI.

All this defending of the "march of technology" by Sean makes me wonder if I am the only one not climbing into the clouds? I use LK8000 competition version and can attest that it still does everything I need to do in VFR weather.

Anytime.

Once again I urge you to sell your glider

Sean, why are you the only person out there making a huge mountain out of this molehill?

The rule is simple - don't show up with a gyro AH or T&B (or the ability to display USEFUL attitude data) if you want to race. *Yes that means no LX with AHRS. You also can't show up with 18M wings at a 15M race - its the RULE!

All your whining about smart phones and PDAs is exactly that - whining. *Without gyros, none of them display USEFUL attitude data. *That includes the latest smartphones. *Just because it has a pretty "HUD" app doesn't mean you can use it to cloud fly! And no reasonable CD is going to waste the time worrying about iPhone apps or what version of XCLKSoar8000 you are using!

If you cloud fly and get caught you will get booted, regardless of what you have in your cockpit - so stay out of the clouds!

If you feel so stongly about changing the rule to allow gyros in the cockpit during a race, try building support from the racing community then approaching the RC with a reasoned argument and proposed solution.

And to be honest, I wouldn't mind having a backup AH in my cockpit - but it's just not a big deal for me.

But your approach of throwing a temper tantrum on RAS is REALLY counterproductive, IMO! - well, except for starting the hissy fit between Max and Paolo - as a SeeYouMobile user that was entertaining!

OK, I'll shut up now. *Good luck with your contest at Ionia - I really enjoyed the times I raced there - great location and great people.

Sorry Don - try again. Following is quoted directly from Annex A of the Sporting Code covering rules for World and Continental Championships. It's terribly inconvenient for your argument:

4.1.2 Each competing sailplane shall be flown within the limitations of its Certificate of Airworthiness or Permit to Fly and:
a. Must have been issued a valid Certificate of Airworthiness or Permit to Fly not excluding competitions.
b. Shall be made available to the Organisers at least 72 hours before the
briefing on the first championship day for an acceptance check in the
configuration in which it will be flown. This configuration shall be kept
unchanged during the whole competition. Exception: In the Open Class only it
is allowed to change complete wing panels and/or winglets. No instruments
permitting pilots to fly without visual reference to the ground may be carried
on board, even if made unserviceable. The Organisers may specify
instruments covered by this rule in their Local Procedures.
