Ok, I think I will have to double check if the VOR actually has DME....

Another technical question: The service ceiling is supposed to be 25000 feet... is the Twin Otter even pressurized? I would guess this makes flying above 10,000 feet slightly uncomfortable....

In fact, the DME in current svn can only work well for VOR, not the GPS or route manager. You DO NOT need to click anything, don't even touch it. The only thing you need is to spin the NAV1 frequency to the VOR you need, then, the DME will show the data for you. If not, fly the aircraft... just fly it, because if the VOR tower is too far away from you, the higher altitude is needed for getting the signal.

There is an open bug, the DME can only show one single digit and decimal digit. This is a 3D glitch and it spent me a lot of time and still can't solve it. The temporary solution is that, change your view point to Co-pilot position, then all digits can be seen.

I hope this help. Thank you very much.

Sincerely,
Bo

Open the map and you will see.
This is a VOR that has no DME.

This is a VOR with DME.

According to Transport Canada, if you fly above 10000 ft longer than 30 minutes, oxygen mask should be provided to everyone; if you fly above 13000 ft for even one second, oxygen mask should be provided to everyone.

The Twin Otter doesn't have a pressurized cabin. It's service ceiling is indeed 25000 ft by design, but because of the need of O2 the typical cruise altitude is not above 10000-12000 ft

@lanbo : have you asked for help on the PAF forum ? I'm sure somebody could help?

No I haven't, but I think Patten and PAF team have already known the bug, because we discussed it before. He spends most time on the Rembrandt engine, not the ASL, so it may take time to be solved.

I have another idea. I hope to know your opinion about Bendix Ki266 DME. This DME looks better, and all digits can be seen. Therefore, if you all agree to port, I will port it to the DHC6.

So just let me know what you think.

I would agree to use this DME, although it seems a bit low poly to me. If you agree, I can make a model with a higher quality without the need to change the code.

Then I would take the KI266 from the Seneca II and modify it.

I definitely agree, but I use the one from the Cessna 172p-detailed in the picture above. Is it the same as what you said in Seneca II? :shock:

Almost.
This is what I've done so far:

For comparison see this:

This is approximately what I aim for.

It looks cool.

Just post here when you have done.

But I am still considering and worrying about the vitre so much. What if we add a vitre for the Ki266, then the dme damages like being cursed :shock: .

That's could indeed become a problem. But let's worry about that when this problem occures :wink:

For bonus points, implement the ventilators above the pilots as seen here:

When I modified and polished the FDM of this aircraft model, I always flew TFFJ, TNCS, or Lukla for testing. This model's FDM is basically good and everything matches this video so well. :D

We can have some flights in TFFJ and TNCS, and post our own video here. :mrgreen:

The fan can be done, not very difficult. my next concern also includes the external power unit, pitch trim wheel model and animation.

Rudder trim, PTT, nose wheel steering bar will be on the yoke.

I also want to implement the bus tied, but some electrics systems have to be rebuilt...

A lot of things I want, but let's implement them step by step.

No worries. I just flew the Twin Otter from Hanover, Germany (EDDV) to Hamburg, Germany (EDDH) with online ATCs. Using Rembrandt is much nicer, especially at night, and the atmosphere feels right. The DME also worked once I knew how.

I'm using the dialog for the Autopilot, because the buttons on the panel don't seem to work consistently for me, but that's also probably my fault.

As far as I know, both the rudder and the evevator trim are on the console right next to the pilot's seat:

I also had the plan to implement an external power unit, but I didn't dare to touch the electrical system. :roll: I'm looking really forward to see this implemented, as well as the nose wheel steering bar! :D
