Question about real Airbus panels

[marciano]

I am still working on my A320 panel and some information are missing to make it as realistic as possible:
- On the barometric pressure indicator, the barometric setting is displayed in "in Hg" or in "hPa", and above is a indication displaying "BARO" or "QNH". What is this latter indication?
- On the Engine Dispay Screen, which displays N1, N2, EGT, etc...), there is a "CL" or "CLB" indication displayed in %. What is it?
- I found some information about engine startup in Automatic mode. I'd be happy to have more information about the manual startup.

If you have any info about all this, please let me know.
If you don't have the answer, but if you can guess it, please tell me...

Thanks in advance !!

Well, stuff here checklist-wise http://www.eflight.com/a320.htm, and look onn airliners.net for pictures of the MCP, there are loads!

The BARO is altimeter setting in inches of mercury (Hg), the QNH is the altimeter setting in hectopascals/millibars (hPa). It makes it a lot easier to set the altimeter no matter what part of the world you are in since you don't have to convert back and forth. The 'CLB' setting on the ECAM (I think that's what Airbus calls it, EICAS is Boeing) sounds like the maximum allowable power setting for climb. There are several other power settings that would be indicated depending on what the crew sets. It will limit the power on the engine to the correct parameters for the desired flight profile, things like Takeoff/Go Around Power, Flex, and Cruise settings. Hope that helps.

First, I'm sorry to say that about the altimeter setting, I think you're wrong. I say that because of the 2 pictures of a REAL Airbus panel that I saw (attached to this message). They both show an altimeter setting in hPa, but one has the BARO indication, and the other has QNH.

Then, your explanations about the CLB and % display are perfect. Now the question is: how can I simulate this in FS2002? I'll think about it...

Thanks for your help !!

PS. If you can't see the attached pictures, please let me know and I'll send them to you directly.

Can't see the picture of the panel. I'd love to have a look at it. I'm in no way, shape, or form, a gauge programmer, but Bill Grabowski has incorporated a gauge that selects flight modes in his ERJ panel (or at least appears to).

Eric,

When setting the altimeter for departure, or arrival, you are given the QNH setting. This is the measurement of the pressure at sea-level at that location, either in mb(hPa) or Hg depending on where you are in the world.

At a guess, the display you are on about, shows if you have the altimeter set at the standard (BARO) setting of 1013.2mb(hPa) so that the altimeter shows the Flight Level or you have QNH set. (I can't see any pics, so its a guess and this is common in most airliners)

Hope this helps

I'm sorry, I was wrong in uploading the image, here it is.
As you can see, one image has BARO indication and the other one has QNH but both are in hPa.
When you pull the knob to set the 1013.2 hPa setting (or 29.92 inHg), then "Std" is displayed instead of the barometric setting. I have other pictures of real panel showing this.
Thus, I still wonder...
- I understand what QNH is
- Above transition altitude, standard setting must be set (1013.2 hPa or 29.92 inHg)
- I'm still not clear about the BARO indication. What you describe is the standard setting, with "Std" displayed.

Anyway, my A320 is almost done, and this question is not that important...

Just to make things a bit more complicated, I've also seen photos with QFE indicated (height above aerodrome level). It's an interested subject this. I would also like to know how the crew change between BARO/QNH/QFE. I'll keep searching...

Thanks for bringing a little more complexity...
I don't know where the QFE indication can be displayed, as there is only room room for QNH and BARO indications.
The question about the command has been on my lips for a long time as well: where do the pilot change the QNH/BARO setting? I don't know. I gave up... My instrument will only have the inHg/hPa selector, until we find more information.

Anyway, thanks for your help, and if you find more information, please let me know !!

Thanks,
Eric

BTW, if you find pictures with the QFE indication displayed, please send one to me: emarciano@free.fr
