Thomas,
The D1 and D2 come with a RAM mount and a suction cup base. The nice thing about this is that RAM has plenty of options that allow you to install it in different ways, like the rail mount found here, so you don't have to do custom work:

I used a Ram V-Shape mount to connect it to the roll bar brace.

I'm shopping too and saw this for attaching to the roll bar brace. Fits .5" to 1.25" tubes and has the B size (1") ball which is what the D2 comes with.

Default Pressure alt?

It would be great if you could enter the pressure and have the GPS do a conversion to give you pressure alt using the lapse rate or via a built in static port like my watch.

Is there a reason why folks wouldnt want pressure alt?

Default Replace Compass?

What are everyone's thoughts about this unit replacing a compass on the support brace? I've never been happy with my vertical card compass and this unit can't be less accurate! Man would it be easy to wire-in!

Thoughts?

There are a bunch of issues here:

1) Static in a cockpit is generally hundreds of feet off from the right altitude, due to the airflow around the aircraft. It can be high or low depending on the plane, and changes with airspeed. This is why planes have external static ports.

2) Static in the cockpit doesn't work in pressurized planes

3) GPS altitude isn't wrong. In fact, on a perfectly standard day, pressure altitude and GPS altitude are the same. Personally, I've never seen a standard day though.

If we had GPS when we started flying, we would all just fly GPS altitude. We use pressure altitude because it's what we have, and when everyone uses the same baro setting, if you are in the same place, you are using the same altitude reference. But that works because the altimeter doesn't know or care if the day is standard or not, it just knows the pressure where you are right now. So there's no way to model this in GPS, since the deviation from the ground station is totally unknown without a pressure sensor.

There is a great thread here on VAF on GPS vs Pressure altitude. http://www.vansairforce.com/communit...ad.php?t=89446

So to sum it up, yes, people would want pressure altitude, but there is no way to do that in a certified plane without hooking to the static system, which would require the D2 to be certified.

The D1/D2 give you GPS ground track, not magnetic heading. So it isn't a direct replacement for a compass if that's what you actually want. In some cases it's much better, but it isn't the same.

In a certified plane, you cannot remove the compass for this. That would require this to be a compass and to be TSO'd to the compass requirements. In an experimental, it's all up to you.

Dynon people,

I would advice you to build a D3 based on D2 which has pitot and static port, so D6 owners may be able to upgrade to a lighter and smaller backup unit with the plus that is a wifi data transmitter to ipad

Cheers,

Default WTB Dynon D1

I am in the market for a used D1 if you are looking to upgrade to the D2. Send me a private message.

Thanks, Dan
