Distance display

[stebbo]

Hello All,

I've just downloaded the GA737, and am trying to learn how to fly this great airplane.

When flying an ILS approach, I'm wondering if it's possible to get the distance to the airport displayed on the EADI display. I've seen some other panels where the distance, ground speed and track are displayed on this display, along with the ILS frequency and title.

Any help would be greatly appreciated.

Cheers,
Chris.

Hi Chris-

Simply - if it ain't on the real one, it ain't gonna be on this one. ;-)

As far as the distance goes, if the station outputs the necessary information, the distance will appear on the EADI.

If you have an approach chart for the airfield, look around and see if there is a VOR or TACAN station on the field. If there is a VOR, set this channel in your Nav 2 radio, and select VOR2 instead of ADF2 on your RMI. This won't show on the ADI, but it'll at least give a distance readout right next to it. If the ILS itself has DME, you'll get that distance on the ADI. If there is a Tacan, add 53 to the channel number, and divide by 10, and add 100, and you'll get a frequency for the DME portion of the signal you can use in a VOR. (Ex: Tac chan 86 + 53 = 139; 139/10 = 13.9; 13.9 + 100 = 113.9 = VOR freq to recieve DME from TAC station).

If there is a compass locator (NDB) at the outer marker, you can program this into the FMC as a waypoint, and fly LNAV until on final, and you'll get a distance readout to the outer marker, which is usually about 5 miles or less from the field.

Of course if you're wanting to use the autopilot for the approach, you need to have both nav sets on the ILS for autoland, and you may not want to fly LNAV that long. But if you make the airport the last fix on the FMC, you can always do a quick check of the FMC for distance to the field.

If you're on an ILS display on the EHSI, you should see the ILS identifier and range. Range is at the top-left, and it will also be on the RDMI to the left of the EHSI too.

Do you have the EHSI in one of the two ILS modes?

...or you can fly with LNAV engaged until you almost reach the RX point and RW appears with its distance as next waypoint on the EHSI. Than simply turn on HDG select and continue.
You will now see the distance to the runway threshold on your EHSI.

It sounds like maybe the ILS approach I'm using doesn't have a distance element. How do I check to see if there is a distance element within the ILS ?
