IFR with a VFR GPS

Sorry, I mean assuming the aircraft is in radar contact.


Radar monitoring is required for off-airways routes beyond navaid
altitude/distance limits. So if not in radar contact your route will be via
airways or between navaids within the established limits. You'll know the
VFR GPS is unreliable when it no longer agrees with your more traditional
navigation radios.

Assuming the pilot is continually tuning his traditional navigation radios,
then including those in his instrument scan. And what if he does not?

You asked what the risks of flying IFR with a VFR GPS are. There's one.

Why would he do that?

But I didn't ask what are the risks of flying IFR using a VFR GPS
exclusively.

You didn't ask what are the risks of flying IFR using a VFR GPS in concert
with other navigation instruments, either.

No, I didn't. I didn't have to, as the the other navigation instruments are
required to be there. The bottom line is you haven't identified any risk
from flying IFR with a VFR GPS.

Are they required to be used?

Yes I did. Just because your newsgroup pride won't let you recognize it
doesn't mean it didn't happen.

Are you seriously going to maintain that the risk in flying IFR with a VFR
GPS is that it will cause the pilot to leave his required nav radios off and
he will then not recognize if he has drifted off the assigned airway in a
nonradar environment?

Why wouldn't you use all available information? I never rely on any one
source if I have supplementary sources of information available, GPS or
no GPS.

I was merely identifying one risk of using a VFR GPS, not stating that
everyone who flies with a VFR GPS does not use all available information.

Recall that the NTSB accident database has at least one recent C172 fatal
accident where the NTSB concluded that the pilot was flying a GPS approach
with nothing but a VFR GPS.

Isn't this also true if you fly airways but DON'T use a VFR GPS?
