I don’t consider airports used by small jets commercial.
If you consider charter commercial so be it.
Put another way, no air carrier airport has had it’s IFR approach decommisioned and gone to GPS only.
Dallas Love Field has ten instrument approaches. four are ILS, six are GPS. Dallas Ft. Worth has sixteen GPS approaches. Atlanta Hartsfield has twenty GPS approaches. Chicago O’Hare has fifteen GPS approaches. You were wrong.
You said “No air carrier airport has had it's IFR approach decommissioned and gone to GPS only.” Would you like make a little wager on that? How about the airports served by commuter airlines that have had a GPS overlay on their existing NDB or VOR approach, and then the NDB or VOR has been decommissioned?
You don't know the definition of air carrier. I have an air carrier certificate that looks exactly like the ones possessed by Delta, American, etc. The difference between those operations and mine is that they fly scheduled routes, I fly on demand. The training, standards and inspections that we both go through are nearly identical.
You said “If you consider charter commercial so be it.” Yes, I do consider charter commercial. So does the FAA, the insurance carriers, airport management, the IRS, and my many satisfied customers who enjoy flying ten thousand feet higher than the airlines, above the weather, in luxury, on their schedule, and without a TSA strip search.
