GPS Question

Except for flying an approach at the alternate:

Ref: AIM 1-1-19, paragraph f.1.(b)(8)
Restrictions

"For TSO-C129/129A users, any required alternate airport must still have
an approved instrument approach procedure other than GPS that is
anticipated to be operational and available at the estimated time of
arrival, and which the aircraft is equipped to fly. If the non-GPS
approaches on which the pilot must rely require DME or ADF, the aircraft
must be equipped with DME or ADF avionics as appropriate."


Not so. One can still fly a GPS approach at the alternate. You just need the
other equipment installed. If you have approved WAAS avionics, you may plan
to use any instrument approach authorized for use with WAAS avionics at a
required alternate.
