Im sure this will be a really fun topic - So I'm doing some research and find a thread (diff forum) about what it takes to make an experimental legal to fly IFR. Well the good folks at the EAA published a document more or less addressing the issue. However in their document was this little interesting paragraph -
"It is important to note that the GPS is approved for ?supplemental? navigation only. A primary
system based on ground facilities must be installed in the aircraft as well. This requirement is
found in Part 91.205(d), by way of the following statement:
?Two-way radio communications system and navigational equipment appropriate to the ground
facilities to be used.?
As we are required by our OpLims to equip the aircraft in accordance with 91.205, this statement
tells us that our primary navigational equipment must be based on ground facilities (primarily
VOR). As this is the case, a homebuilt with only a GPS installed would not be legal for IFR
operations. "
Does anyone believe this? How can anyone ever shoot a GPS approach to an airfield without a VOR? I didn't see a date on the EAA document so am assuming it is 10 years old at least.
If the FAR stated "OMINI direction navigation equipment is required...blah, blah, blah" then I would get it. BUt the statement was "Navigation equipment appropriate for the ground facilities to be used". To me this means if I'm filing IFR to an airfield with only a VOR approach then I need to have a VOR installed. If it has both a VOR and GPS then I could have either as they are both "appropriate".
I'm no lawyer but this seems easy to me....
I was planning on doing away with the old ground based navigation equipment and go entirely with GPS... still am actually.
Any opinions here?
