Recently the COE VOR was notamed OTS. Coincedent with this the KSZT LOC/DME
was notamed NA. The explanation given was that the COE VOR was nessasary to
fly the tranition (COE is the IAF) and the missed approach (the missed ends
with a hold at the COE VOR). I contend that GPS can substitute for the VOR
but I can't find it witten down anywhere. The KSZT LOC, DME and ADF are all
working properly. Our question is: Was the KSZT LOC/DME approach
improperly NOTAMed NA? Can you cite a source? Remember we are talking
about substituting GPS for the VOR to fly the transition, we are not talking
about substituting for the LOC.


We deal with the same thing here at BIL. We have an ILS that requires
radar and DME. Whenever they take the DME out of service they notam the
whole approach OTS. Nobody can give me a good reason why the approach
can't be left in service and just have the notam state that DME is not
available. You can just chalk it up to the FAA being horribly behind
the times when it comes to GPS.
