I fly airplane without IFR GPS (IFR student), but ATC is trying to assign us GPS approach all the time (when coming into airport with ILS). As far as I understand, GPS approaches are used, even if they are less critical in busier airports. Besides, sometimes ILS is not available in bigger airports as well.
- toomuchtodo 13y agoILS was not available on the SFO runway the Asiana aircraft crashed on ~2 weeks back: http://en.wikipedia.org/wiki/Asiana_Airlines_Flight_214 http://en.wikipedia.org/wiki/Asiana_Airlines_Flight_214
- hedgie13 13y agoYes, but the weather was clear. No need for ILS in such weather.
- toomuchtodo 13y agoUnless of course you've never landed at SFO before in an aircraft you're barely type-rated on.
- mikeash 13y agoNeither should matter. A visual landing at any airport is pretty much the same, and the basics don't change for different aircraft. There's nothing at all tricky about a visual approach into SFO.
