I am really liking the Lightning but here is my question - I noticed that there appears to only be 1 tachometer and 1 manifold pressure gauge. Shoudn't there 2 of them, 1 for each engine? Am I missing something obvious? Thanks.

The instrument panel was simplified.

To save space there is only one tach and one MP gauge, but each gauge has TWO NEEDLES. Pretty clever, eh?

Also, don't pay any particular attention to actual values on the manifold pressure gage. It's totally off for most aircraft. Needle movement is great, numbers, not so great. Actually, I'm surprised none of the book-quoting experts have pointed it out yet. I'm not complainin' though. The needles get the job done.

Cosomokart,
Maybe you should clarify that the panel reflects the 'simplification' found on the ACTUAL panel? There really was a common RPM and common MP gauge on the Lightning.
Your post, although accurate, makes it sound like the "simplifying" was done by Maddox, not engineers at Lockheed as was the actual case.
I'm just saying...........................

Absolutely Chris... my reason for the question was mainly to find out if the panel was accurately rendered. So by your post I guess that it is.

i was lucky enough to know him.

Actually I find the manifold pressures for many aircraft (all that I am familiar with) are very reasonably accurate. No doubt manifold pressure is a complex subject, and the game does not model all of these complexities, it is quite accurate in the sim. The FW190's for example are pretty much spot on.

What was the name of that book that he wrote? I use to have it about ten to twelve years ago, but misplaced it somewhere.


P.S.
I saw a training video on the P-38 just the other day that talked about manifold pressure for take off & cruising speed.

The take off was 3000 RPM's and 40in. of manifold pressure & cruise was 2600 RPM's and 37 in.

AEP is set at 40 in./2800 RPM at 49% power, 37 in./2700 RPM at 40% power, and 60 in./3000 RPM at 110% power.

You are wrong.

The P-38 had separate gages for the two engines.

The simplification is only present in this sim, not in reality.

That's a restored P-38 with MODERN GAGES.

The real thing had separate gages for each engine.

Yeah... what's the link to that video? It is really excellent! http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

By the way, you'll notice that the panel in the video has SEPARATE GAGES FOR EACH ENGINE.

Exactly. That's why Lockheed did it the right way. Take another look at that restored P-38... there's ACRES of empty panel space where the real gages used to be.

This sim, on the other hand, is faced with other limitations, so they used 2 needles per gage.

Sorry about that, I should have posted it.

I may yet be convinced that the late model P-38's had a different cockpit layout. Can anyone come up with evidence for a cockpit change that affected J or L model P-38s? Maybe that's all it is. Still, from a safety and ergonomics perspective, it's a bad idea. In an emergency the pilot can't tell which needle is which.
