747 measurments
« on: Thu, 9 Jun 2011 07:56 »
Hi Guy,


Making a mock of a pedestal, until my real -400 pedestal arrives. I have the width of 438mm for the radios ect. Does anyone know the exact length say right side radio to the printer not the outside measurement. I am requesting the inner. Please don't give me what you think measurements there is a few hours of building on the line. I need exact with a tape measure for a real -400. Could someone cross check the inner width?

Does anyone have a tape measure of the source selector left to right (outer measurements).?

Also the whole width of the glairshield? Overhead panel width and length? Height and width of the maintenance panels if it was in 4, only need the one of them dimensions. Autopilot height and width including the MDS (cancel recall panel).

Need a cross check, want to see how close I have made to real deal.


Blake;)

Blake,

See my tutorial here:

http://www.mycockpit.org/forums/content.php/165-Hessel-Oosten-s-Panel-Building-Focussed-On-Dimensions

And calculate it yourself !

Don't let the 0.1875" panel gap between the 3 vertical columns of overhead panels ("P5") confuse your calculations ;)

there are 50 dzus fastner slots on the 744 pedestal ( the one i counted) - using hessel's wonderful tutorial (i never knew there was someone actually called Mr. Dzus...!) the calculations should be easy - for dims on the RMP, ATC, check out the gables site, they have detailed docs on the panels.

I would hold off building the final pedestal until you have your panels in hand and laid out - minor variations can exist from vendor to vendor in the sim world... of course this is not an issue if you're building the panels yourself, in which case i would start making them (the panels) only after your real 744 pedestal arrives.

hope this helps!

Hi guys,

I am sourcing out b747-400 instrument panel measurements from Boeing, anyone interested?

When I receive the measurements from Boeing, maybe someone can work a 3D CAD model that is easy for everyone to understand and use for what ever purpose they seek.

Thanks Farrokh, I am hoping to get the measurements first. Fingers cross.

Great DSUZ tutorial. The panels are built around the DSUZ. If you work out the DSUZ pattern, you can work you panels length and width.

I have the width of 438mm for the radios ect.(sic)


I have the inside measurements at 438.15 x 485.775mm (using an inch to mm conversion of 25.4mm/inch)

Does that match up with the hole dimensions?

Of course, there is no guarantee that the 747-8 will be anything like this  ;)

It is the same the manufacturer of the radios, The manufacturer is Gabel engineering have a look at there website.

I know the pedestal for the -400 and -8 is 146.05mm x3 wide. The length if I scale the drawing is 486mm.

I have some cathay pacific drawings. The width of the overhead is 219mm +291mm+219mm. The height is 611mm. The MCP is 73mm in height 417mm long. The EFIS is 119mm width and the EICAS control is 66.1mm width.

What you guys think. Getting close???

I think you should use inches (as recommended previously)  :mrgreen:

The aircraft overhead panel (P5) is 8 5/8" + 11 1/2" + 8 5/8" with two gaps between the columns (each 3/16). This gives a total of 29 1/8"

Lol.

There is a good google convertion for inch to mm. We all know metric is superior :roll:  .

I know what your saying it is related so the DSUZ lining up. I just wanted to get the ball rolling, for cockpit builders, there are so many bad measurements out there.

 I cross check the metric and imperial numbers sound like we might be getting some where with the measurements.  

Does anyone know the MCP, EFIS and EICAS control. Width and length. Please in inches, for Americans :lol:

And for Englishmen and for people in, say, Australia, working in the aviation industry

Blake, perhaps you could reveal your source of dimensions? There is no point me giving you values for comparison sake if your source is me: In the early days of PS1, a gentleman drew up some very nice scale diagrams using a comprehensive set of measurements taken by me to be distributed amongst bona fide PS1-users.

Unfortunately, I have lost contact with this gentleman, and I don't want to distribute these diagrams willy-nilly without his permission (since he had put a lot of time and effort into them).

Cathay Pacific panel diagrams from their fleet. I had known measurements from the radio manufacturer. Plus DSUZ tutorial guy.

Cathay diagrams I scaled had no measurements hence mm. I knew the radio measurement and the width of the overhead panels and cross checked. I also had home made 747-400 CAD drawing from mycockpit.org of the MIP, they crossed checked the cathay diagrams.

The height of the MCP, EFIS and EICAS control crossed as 73mm. I found a discrepancy is length of the MCP. The mycockpit .org was 435mm and the cathay diagram works out 417mm. The is a 767 I found on the net, that had a tape measure on the MCP is was around 415-420mm. Too hard to tell.

That is where I am at.

I have the width at exactly 17 inches. This is one of the reasons I use inches -  no conversion errors.

Seems I misunderstood you. I thought you'd already spent 1000s of hours on this project?

EFIS CAGE INSIDE DIM:  123 MM X 80 MM
MCP+DISP CAGE INSIDE DIM: 500 MM X 80 MM

Note that the MCP/EFIS rack has a 2/3 mm lip over the top edge -

Sorry, in MM, I know Boeingworld is inches only....

I confirm 17 inch across for the MCP - but from my old dakenskys panel...


fc

note re. one of your earlier posts - be aware that the 744 pedestal is a fused unit with the TQ - there's no separate box for the ped, the rear cage plate of the TQ is the fwd plate of the aisle stand, and both sit one one floor mount frame.

Lol John.

I remember my first try at a wooden carved TQ handle 7 years ago. It starts as a dream, followed by a desktop plastic yoke and rudder pedals with a whole lot of research and building to hopefully have a pretty close replica. I ended up with a ok 767-300 that I used as a good procedure trainer in between. This left me wanting a more complex simulator. What better a 747-8 replica.
 
Where did you obtain 17 inches. My MCP that I made is 432mm (approx 17inches). I am not 100% sure this is the measurement. Could have Boeing modified this measurement on later -400?

I have been on this project for a year. Time goes by fast when you want your sim right. My advise to cockpit builders is resist tempation to fly your simulator by short cutting. You will end up with a inferior sim. Research, do it right and take your time. Rome wasn't built in a day. You will save more time and money if you do it right. This is if you want a 95% replica. Remember Aerowinx is close as you can get to the real thing.  Why not have the hardware to match your software. :D  

Farrokh, The MCP 80mm, I am not sure with this one. Is it a FDS MCP? I am 90% sure 80mm is not right.

I am aware of the lip ect. I am interested in panel sizes for the pedestal. Cheers for the heads up.

I took this measurement from a -400 panel with a steel tape measure marked in inches ;)

So, now you have 3 sources which agree within 0.2 of a mm. I would be pretty happy with that. Note that there are small gaps (of various widths) between the panels on the lightshield, so the total width of the "tray"(frame) in which the panels sit will not necessarily match the sum of the panel widths.

Thank-you John.   :mrgreen:

If it was a tape measure I will take your word.

It is still a mistry why the Cathay scaled diagrams worked out to be 417mm. Have a look at this http://www.simpit.de/b767dim/glare/glare011.JPG. In mm.

And this, http://www.simpit.de/b767dim/glare/glare003.JPG
For Farrokh have a look at the tape measure if you compare to the MCP it is around 75mm

Interesting. Certainly room for doubt.

Unfortunately, I don't have the original drawings. I'm looking at the scale diagrams (created by the other gentleman) with measurements on them. I'll recheck tomorrow on the real aircraft if I get the opportunity.

I also thought the 767 and 744 panels were similar.

as posted, those numbers were for the mcp/efis/dsp CAGE - not the units themselves  = ie, the compartment into which they fit.

The panel measurements I have are:
MCP: 17 in WIDE x  2 & 7/8th in TALL
EFIS: 4 & 11/16th in WIDE , 2 & 7/8th in TALL

Dont have a DISP panel ref -


cheers,

Cool Farrokh we have the same height.

Maybe the -400 and -400ER are difference, more room for the small LCD's in the -400ER.
