Help & Advice on an avionics upgrade path

Jeff:

Any chance you have that plastic template still hanging around???

Tom,

I might still have the template...I wont be able to check until Friday as that is the next time I will be out at the hangar.

That is awesome Jeff! Let me know what you come up with. Since your new panel is 95% what I would like may panel to be, it would be a great starting point. Keep me posted!

I thought I would give some follow up on the UAvionics AV-30C certified indicator discussed earlier on this thread, as I did get clarification from them beginning of this week. I got the following emails:

"Hello Whitney,

Your aircraft was initially added to the AML but the FAA has removed it because of the twin engines. We are trying to get them to put it back on and it looks like they are going to do it but it may be a month at their pace.
The newest firmware supports the dual vSpeeds as well.
We have had a lot of customers doing field approvals with no issues.
Sorry for the confusion.

thanks,

I personally had one installed in the time window when Skymaster approval was first given and noticed one on a member's panel photo, so got additional follow-up regarding one already installed (as I bet an update would be required):

"Whitney,

When we have the update there will be 3 ways to do the update. One will be with a serial cable to a computer. We will also be using something called an AVLink that will wifi the software update to the AV-30. Or if you don't want to do any of those things we will have you send in the unit.

Thank you,

Stay tuned. May be additional option to consider.
As I previously stated I have kept my OEM indicator too, as it drives autopilot.
PS-don't shoot the messenger

WSLADE, I hope they do get it approved for the 337. I would really like to have one.

Even if they do, I wonder if it will be approved for turbo and P models, since the published specs have a limitation of 200 knots, which both of these models can easily surpass in cruise flight?

[JAG]

Mark - I believe the AV30C is approved for single engine aircraft up to a 300 knot Vne... This should not pose a problem getting approval for the P337.

But the bigger question I have is what modifications do you have for the Skymaster to cruise faster than 200 KIAS? Ha ha - just a little humor, I think you were referring to TAS.

Here is the actual wording from their website: "The current AV-30-C AML applies to Part 23 single-engine aircraft operating under 200kts."

I thought the limitation meant TAS, not IAS. But that does make sense. The actual wording does not mention TAS or IAS, but if you default to the conservative definition, it means TAS.

Evidence to support my interpretation is this: Look at the AML for Bonazas (Under Textron) - only the NA models are approved, there are no TC models listed on the AML!

Also, if I understand correctly, there is no way to have a blue line on the airspeed indicator under the current software?
