Where do i find the Landing Altitude?

[737ngx99 1]

Hi!

 

When im gonna enter the Landing Altitude up on the overhead panel i dont know what i should put in!

Wheeling do i find the Landing Altitude Numbers?

 

Thanks!

You can find  it in any ils approach plate ,  its called threshold elevation, and you enter this in,  for example  if the airport had a threshold off 400 feet you would enter this in the the overhead panel

 

here a quick tutorial on the ils approach chart on where you would find  the elevation info there are others  around  just google  it  and it will bring up more

And if you want  to find  the charts of  the airports heres a link of  most of  the airports  where  you can get  the charts etc

Thanks for helping me!

 

So if i have the Approach Plate in fron of me, where does it stand?

At the top of the approach plate, there are several boxes that show the various airport communications frequencies, the frequency of the ILS etc. At the right side of that section, right under the word "Stockholm", is a box that shows the airport elevation, and runway threshold elevation, which for this approach are 137 feet and 98 feet. You would enter the runway elevation (98 feet) into your pressurization panel. In most aircraft with digital pressurization controllers, the landing elevation is in increments of 25 feet, so the closest entry to "98" would be "100"

This is insignificant, but are you sure it is the threshold rather than the airport elevation?

On a Jeppesen chart, the box shows both the main airport elevation (upper number), and the threshold elevation of the specific runway. (Lower number). The differences are normally so minor, that it really won't make any difference which number is used.

 

A US NOS approach chart will have the same information on the upper-left section of the chart.

Or

 

FMC, "INDEX", "REF NAV DATA", "AIRPORT IDENT". Enter the ICAO code. Then enter the "RUNWAY IDENT" (e.g. "15L"). Elevation data is then displayed.

Here's a quiz question for you. What if the landing elevation is above 6000'?

I use this to, but usually don't bother with the runway.

The 737 has an optional high altitude swithch to use in a case like this. I don't know if it modeled on the NGX or not. Denver at 5434 feet is the highest I have ever landed. I know you set the landing altitude to 6000 feet at takeoff and at T/D flip the swithch on and dial in the altitude up to 14000 feet but beyond that I fail the quiz.

Yeah pretty much. "High altitude airport" in Boeing terminology usually means landing above the 8400' limitation which I am not referring to nor do I know much about that type of operation or the switch. But if landing somewhere over 6000' there is this little procedure to limit the cabin altitude to 6000' in the cruise (as you mentioned). Have a look in FCOM1, Supplementary Procedures, Air Systems, Automatic Pressurization Control - Landing Airport Elevation Above 6000'. Basically, as you say, set 6000' on the ground and at top of descent set the actual landing altitude.
