If flown with GPS/ WAAS enabled certified equipment in accordance with TSO-C145A or TSO-146A installed in accordance with the provisions of AC 20-130A or 138A, no conventional navigation equipment alternate approach (VOR/ILS) requirements are necessary, as when flying with TSO-C129 certified equipment.
