ATMaster:
Hi guys!!
I am aware that in some airports in the US, France, etc. there are small airports with VOR/DME, LPV approaches implemented. However, there is not even an AFIS service in such airports.
I assume that in such cases the Air-to-Air frequency (A/A) is used to report the position constantly. I am looking for the regulatory framework (either FAA or ICAO) that described operationally how such procedures shall be flown.
Can anybody give me a clue about the regulatory document I should look for?
For the U.S. it's covered in the U.S. Aeronautical Information Manual (AIM), which is available on the FAA's website for download.
FAA airspace policy requires that flight inspection determine that communications exist with ATC at the IAF. This can either be to the center, an approach control if nearby, or through Flight Service Station, which in turn communicates with the controlling agency (center or approach control, as appropriate.)
If there is no communications capability below the IAF altitude you are required to close your IFR flight plan by landline or wireless telephone. There is a universal telephone number for FSS in the AIM, but pilots who regularly do this at such an airport usually obtain a direct number to the center or approach control that is always answered (in other words, not their business line).
Flight inspection also is required to determine that communications with ATC exist at the missed approach level-off altitude and end point (almost always a published holding pattern in the U.S.)
