pmSystems Pre-purchase question

[David Rabiner]

Hi, folks.

1. I notice in the docs that it is recommended that pmSystems run by
itself. I'm out of computers. Is it fatal, slow, or just risky to have
pmSystems run with, say, pmCDU?

2. With pmSystems (and other pm software) installed, it seems there's
nothing needed in an aircraft except for a perfect flight model. The last
time I flew the default 737, I think I was climbing at 3,500fpm with a full

tank. Does anyone know of a (near-)perfect 737 flight model?

Thanks!

It depends very much on your computer, how much free physical memory it has

(so it doesn't swap to file) etc... also... some graphics cards will not
like two instances of OpenGL (graphic driver issues)... thus Glass Cockpit
and pmSystems. Please check with the Demos.

I see no conflicts whatsoever with MCP and CDUs...

What is wrong with 3500 fpm on a full tank when you are climbing out after
takeoff?

Do you know how much physical memory I need?

Oooh. The computer with the CDU had OpenGL problems. GC would hang the
computer.

I'll download the demo and see how it works.

I didn't think 737s could achieve that.

Warm regards,

It depends on the options, just run both programs at the same time and
check
the free memory.

The CDU does not use or know what OpenGL is...

Best solution.

What is the source of that information? As far as I know, the 737 (and many
other aircraft) have to acheive that for a variety of reasons, like noise
abatement, follow a SID etc...

That (if I recall) is why the CDU is on that computer. The PFD would hang
it. But I just ran the pmSystems demo on it, and it appeared to work ok.

As far as aircraft performance goes, it's been a while since I've flown the

default MSFS 737. I just think I remember that in climb thrust we were
going damned near straight up, and I thought others were finding that, too.

I think I remember that the plane was not slick enough in descent, too.
It's been a while. That's why I was wondering if someone had developed a
flight model that more closely matches real life. If what you're saying is

that the default 737 is close enough, then that works for me!

Hey, next question:

Is there a way with pmSystems that I can program joystick buttons do
interact with the pmSystems switches (e.g., landing lights)? I'm thinking
(as I answer this myself) that that is one of the purposes of pmSystems, and

that the answer is yes. If so, then where would I go to learn how?

Thanks, and I hope for a great holiday season to you and family.

Warm regards,
David
