[PW] ?percentage of aircraft using navigation instruments

[Hall, Robert]

Can any one point to where I might get this kind of information:

1.       Percentage of aircraft each year over the past five years that have GPS, VHF Omnidirectional Radio Range (VOR), Non-Directional Beacon (NDB), or Inertial Navigation System (INS).
2.       It would be great if this can be broken out by type of aircraft: commercial, general aviation, or UAV
3.       The percentage of pilots who are rated for Instrument Flight Rules.

I've looked around without success and now have email into the Bureau of Transportation Statistics.

Thanks,

Bob
