Does ILS is only for NAV 1 ?

[Alejandro Rhodes]

I Was checking something ,and I don't know if is the plane or it is like this

Do ILS glideslope approach is only for NAV 1 it doesn't work in NAV 2? :-?

[BFMF]

Though it's possible and usefull to track two VOR stations at once, I don't see how it would be possible to be on approach into two different ILS approaches at once

[Alejandro Rhodes]

What I mean is , it seems to be to avoid this and cause a crash receiving in two diferent radios the same tracking freq to LAND..it could be a security measure , I don't know , It seems auto approach navigation works only in NAV 1.

VOR navigations works in both ...lets wait the pilots here  :-?

If you are making an autopilot appproach, I assume the autopilot would only track one signal, and its probably VOR1.  But you can tune VOR2 to the same ILS and use it as a visual backup.

It's one for the techos.

APR mode tracks VOR1 only.. unless you have a custom autopilot.

Usually only VOR1 has the glideslope bar

In a real airplane, the only limitations are on what type of equipment you're willing to purchase, and how much wiring you're willing to have done, behind the panel.

Whether or not a standard NAV radio can track an ILS, has nothing to do with the radio; be it NAV1 or NAV2... it depends on what type of VOR indicator it's using. All, standard NAV radios can recieve ILS signals... and you can even use a non-ILS indicator to track just the localizer.

When you've dialed in an ILS, the OBS knob becomes useless (though it's good practice to turn it to runway heading for reference), even with a non-ILS indicator.

I've flown many a rental C712 that had two ILS capable indicators.. so you could use either NAV1 or NAV2 for an ILS approach. That's more about redundancy, and having a backup ILS indicator available, than it's about being able to use either. I mean (as mentioned), you would never be tracking two ILSs..  Though in theory, you could be landing at an airport that has two ILS equipped runways, and because of shifting winds you might want to have both ready. But with a flip-flop radio, that's overkill.

Now, as far as autopilots go.. it again depends on the equipment. Most autopilots have their navigation tracking, slaved to the primary (NAV1) VOR indicator (which is also the indicator slaved to the GPS). Some autopilots allow you to choose between VOR indicators, but it's uncommon in smaller aircraft.,, and again about redundancy, as an autopilot can't track two courses at ther same time..  lol

MSFS autopilots are only slaved to VOR1. And (aside from a few third-party gauges), VOR1 indicators are the only ones that are ILS capable. I seem to remember a Rockwell Commander that had a wonderful VOR2 indicator that was ILS capable. It worked wonderfully for tracking ILSs, but the autopilot was still only slaved to VOR1.

In short, the FS Autopilot is slaved to NAV1 source or GPS1 source. Period.

Even oh-so-clever 3rd party solutions are simply slieght-of-hand. Although it appears that the AP is being driven by NAV2 or GPS2, in reality it's still NAV1 or GPS1 doing the driving...  8-)
