Instrument approach OTS components
 

Today a question was posed to me that left me dumbfounded. I've dug through the FAR/AIM but couldn't find the answer. Maybe someone here can help.

You are going to fly an IAP, lets say an ILS. The missed approach procedure has you fly to a VOR. If the VOR that the missed approach procedure is predicated on is out of service, can you still fly the approach legally. All other components of the approach are working properly.

I could be wrong here, but unless you have other means of identifying the VOR (GPS) you cannot fly it legally unless the tower has arranged other means for executing the missed. I'd have to guess there'd be an FDC Notam as well regarding it.

Correct me if I'm wrong here fellas as I don't have any pages to cite from the FAR/AIM.

Cheers

Thanks. Just to be clear, the OTS VOR is only used during the missed approach procedure (where the hold would take place) and not for the actual approach itself.

Yes, but you have to prepare and set up for the missed approach during every approach you fly. Any number of reasons could cause a missed approach during any WX situation. If you aren't able to fly a published missed from an approach you wouldn't be legal to execute it.

If the published means cannot be flown the FAA would more than likely issue an FDC NOTAM stating the alternate missed procedures. At least this is the case in my experience.

Keep in mind I don't have a reference for you in the FAR/AIM, but I'm fairly certain everyone here would agree with me. The missed approach is still a published portion of the chart. Just ask yourself "where would we go if we can't land for some reason and be in protected airspace?".

Hope this helps!

Thanks. I am inclined to agree with you. This question caught me off guard as I have never considered nor experienced the scenario.

I agree with everyone in regards to not being able to legally shoot the IAP since the MAP is part of the IAP.

Take KJVY ILS 18 as a current example. The MAP calls for going to the ABB VORTAC and holding. Since the ABB VORTAC was wiped out with one of those crazy winter tornadoes, a NOTAM was published regarding alternate MAP. There's already an alt MAP on the plate, but there's still a NOTAM for the MAP.

Good question though! Made me think and discuss it for a bit earlier tonight.

If you have an FMS or a GPS, the VOR will still be in the database even if it's been destroyed, as in the previous example, so I assume it would be fine to use. Or ask for alternate missed approach instructions before beginning the approach. Don't rule the whole approach out just b/c the VOR is OTS, it might still be perfectly safe to fly.

Its been few years since I have practiced IAP. Reading up on my IPC to get current again. Just wondering, how many you instrument pilots ID the VOR before shooting the approach? (If the MAP instructions was to hold at a VOR)

Also, when this happens, there will usually be a FDC NOTAM putting the IAP as NA. Happend at RIC for a while last yeat year. Through us off because whoever wrote the NOTAM forgot to put in the language about "unless other suitable navigational systems..." They had inadvertantly NOTAM'd out every single approach into RIC. Our ATC folks called the airport who gave a big "oh Sh*t" and started typing a new Notam. The NOTAM was fixed in a few minutes.

Only during the check ride :)
