I think the best answer would have been to:
Tell ATC your number two nav has seemed to have failed
Ask them to confirm you are on the inbound course at 5.7DME
Ask them to call NEADY intersection for you
Use some CRM and employ ATC to help you out.
Oh, and perform a VOR check before you launch too
After all the approach requires DME or RADAR, this means that they have the ability to both vector you and identify the fixes. If you have a centered needle on your #1 Nav why do you have to suspect that it is out. Just confirm with ATC that is it working. You only need one VOR for the approach.
The comment about the MSA is inappropriate due the fact that MSA are to be used only in emergencies. Quoted from the FAA Instrument Procedures Handbook:
"Well on page 4-6 in this book it paints a picture where ATC is allowing a pilot to either self vector to the IAF on an approach, or they have said "fly heading to intercept". They then go on to say "With no minimum altitude published from that point to the RUBIN beacon, you should maintain the last assigned altitude until you reach the IAF" --- "It is in circumstances like that you may be tempted to use the minimum safe altitude (MSA) show on the planview, although the MSA is for emergency use only, and it not an operational altitude unless you are specifically cleared to that altitude. The ILS procedure relies heavily on the controller's recognition of the restriction upon you to maintain your last assigned altitude until "established" on a published segment of the approach."
