CABIN PRESSURIZATION DISPLAY (767 OVERHEAD)

[shoumi]

hi everybody,

I cannot figure out how to have the overhead pressurization display made?
It shows 3 analog gauge displays. I have some idea of using LCD screen for fuel display, but not for something like this.

On the 767 there is another one also, that is the DUCT PRESS INDICATOR.

Can anyone advise if there are any suppliers of the above, perhaps plug and play, or someway I can make it without too much technical knowhow?


Thanks in advance,

Taufeeq

Hi,
If you are using the LDS as a platform for your 76 then
the duct pressure is in the SDK.
Nico implemented that in his Lekseecon and you can output the data to 2 dig x 2 7 seg.
Or you can check if either Simkits, Flightillusion, Open Cockpits (all 737 style) gauges can work for you.
Not sure if the size is correct, but both has the duct press. diff press and cab temp indicators.
Or you can build on your own the gauges with step motor and a suitable controller.
I think there is a how to in the tutorial section of My pits.

Hope this help you somehow .

Hi Ran,

Yes, I checked on Nico's tutotrials. I have the scripts from Nico, but cannot find anything for the duct pressure and cabin pressurization.

He seems to have only the fuel display on his. I checked both flight illusions and open cockpits, but the price is discouraging.

DO you mean by 7 segment display, or LCD display?

PLease forgive my silly question but I have very limited knowhow. Also, I cannot find your website.

Thanks,

Taufeeq

Hi Taufeeq,
It took me sometime to find it my self :)
Look under the shared codes 2.28 PneumaticControl.txt

Var 9001 name D_LftBld0 Link IOCARD_DISPLAY Digit 131 Numbers 1
Var 9002 name D_LftBld1 Link IOCARD_DISPLAY Digit 132 Numbers 1
Var 9003 name D_RgtBld0 Link IOCARD_DISPLAY Digit 128 Numbers 1
Var 9004 name D_RgtBld1 Link IOCARD_DISPLAY Digit 129 Numbers 1

I've seen one of the 76 builders using 7 seg digits for the duct pres. but
can't find the picture in the B767 builders group gallery.

7 segments are those digits you see like in the MCP.

Ohh about the tutorial, I meant the tutorial section of this site mycockpit (in short my pits :D)
sorry for that :)

Ran.

I think these are the offsets you need if you are using level-d 767 + lekseecon (Page 27 of the lekseecon manual) for the duct pressure indicator

843
Left pneumatic pressure (PSI) as 2 digits Hexadecimal,
e.g.: 0x37 means 37, 0xAA means blank
844
Right pneumatic pressure (PSI) as 2 digits Hexadecimal

734
Left Bleed pressure: PSI
735
Right Bleed pressure: PSI

I think the opencockpits gauge is a good deal since it has the dual needles and those are harder to make yourself. If not the 7 seg display is a good option as mentioned before.
The LCD Display would work good too. Opencockpits sells the LCD controller card too.

You can always try to make your own gauges, I made my own flaps gauge for about $15 + the opencockpits card. But like i said those double needles seem tricky.

Have fun!

Thanks guys for your wonderful input.

Let me get to work and hopefully I will have an update you soon.

Cheers,
