Flying a C172SP with G1000, WAAS. No RAIM check required on the ground. But you are supposed to check for WAAS NOTAMS. The G1000 verifies WAAS integrity prior to the FAF. You then get an indication of which minimums you can use: LPV, LNAV/VNAV, LNAV. So if WAAS NOTAMED prior to departure, questions:
(1) Can you still plan a GPS approach, as if you never had WAAS?
(2) Do you have to do a RAIM check on the ground? Will the G1000 let you?
(3) Must you now have an alternate means of navigation appropriate to the flight?
(4) Do you have to pick an alternate (if required) that has an IAP other than GPS?
Thanks.
