ok so I looked and looked for days now and can not find answer to my question.After landing at several airports that are not a sea level I get a LDG ALT next to the baro readingon right lower of display. This could be a dumb question but thanks for the help.

Check your LDG ALT setting in the pressurization controller.

I did and always set it it was set that day at 3550ft

thanks but is that not a warning or does not matter?

ok I tried that but the LDG ALT is still there. Is there not a way to set it so it shows the ground ligned up with you altitude at current airport?

You can turn this off if you like.See intro manual page 66.

I don't think that's what he's refering to. The landing altitude bar is shown on page 10.11.24 of the FCOM and described on 10.11.25. It's a thin vertical yellow or white bar on the left side of the altitude tape.The "LDG ALT" message is shown on page 10.11.28 and described on 10.11.30 of the FCOM. It's described as "The landing altitude input is no available or invalid."

I had that last night. So if your landing airport altitude is 330 feet, do you put in 300 feet or 350 feet into the pressurisation controller?Brett

On the PFD tere is no message from the pressurization.LDG ALT message is landing altitude failure from FMC

350 but thats not it.In the FCOM on page 689 or 10-31-5 it talk about landing altitude reference but does not tell you how to set it in the FMC

On the PFD tere is no message from the pressurization.LDG ALT message is landing altitude failure from FMC

so how do you set it? thats my question or just leave it and thats OKI have been looking in FCOM for 4 hours now and can not find anything. Going to bed now and will continue in the AM.

The data is stored in the FMC when you select departure and destination.If this data is not present there will be a message. If the message is coming up after the flight, it is normal as te FMC dumps the previous flight.When the data is valid you will see a cross-hatched area on the speed tape

I have been looking in FCOM for 4 hours now and can not find anything.

That's the kind of dedication we like. Gosh, I'm feeling giddy this morning. I have absolutely nothing else to do today, so I guess I'll fire up the ole FSX and see what kind of new approach I can learn.

Isn't this similar to the NO TDZ message in the 747? If so, it's basically saying you need to select the runway you intend to land on at your destination. Once that is done, it sets the field elevation in the system, which should clear the message. Would have been helpful to see what you set up in the DEP/ARR pages.

Exactly !LAND ALT on the PFD is just like NO VSPEEDS. The condition needs to be satisfied.Fred.

He is having that problem after landing and it is a normal condition.

Right, but did he even enter it before landing? I'm guessing he didn't. I don't recall seeing it before or after landing because I make sure I set things up properly (or I just haven't paid attention to it because it's of no consequence to me when I'm already on the ground).
