Listenting to one of the ATC planning telcons at work today I heard that an AA international arrival into JFK was unable to shoot an ILS or a GPS approach due to some instrument problems on the airplane. The plane was then forced to divert to EWR and shoot a VOR approach to 11 which backed EWR up even worse than it already was to allow for this. A couple of questions I have on this?
One, if you can't shoot an ILS approach for some reason, wouldn't this also affect a VOR approach since you are relying on the same NAV radio, unless you can use the FMS to shoot the approach without the VOR?
Secondly, why couldn't they shoot a VOR somewhere to JFK? I am not privy to all the approaches there, but I do know there are some VOR approaches there? Why back up EWR as well?
Thirdly, which flight was it and where was it coming from?

The flight from BUF was for the Miami Dolphins. The plane flew from FLL-BUF drop players off then flew BUF-EWR for the overnight to get cleaned and catered, then flew back to BUF the next day to pickup the team and then onto FLL. Hope that helps

Quoting Apodino (Thread starter): One, if you can't shoot an ILS approach for some reason, wouldn't this also affect a VOR approach since you are relying on the same NAV radio, unless you can use the FMS to shoot the approach without the VOR?
On a 767 the VOR and ILS are separate and not the same radio. In fact if you look at a photo of a 767/757 panel you will see the two VOR receiver nav selectors on the fwd glareshield panel. The ILS tuner and course selector is located on the aft center console.
In the 777, the same rules apply (separate ILS and VOR radios) but they are all tuned via the RAD/NAV button on the FMC
