  3. 3) About 5 miles from HOSAV, your GPS indicates you've lost WAAS, but you still have RAIM. You're not equipped to fly VNAV without WAAS. Which minimums do you use?

    If you lose WAAS, you must use the LNAV minimums.  You aren't required to go missed, but you should re-brief the approach with the new minimums. If you aren't comfortable proceeding with the approach, you can go missed and re-brief with the LNAV minimums.

  4. 4) You tried listening to the ATIS, but the transmitter was down. You listen to Aurora's instead, and WAAS is still not available. What are your new minimums?

    Since you are using the LNAV minimums and don't have the current altitude setting for Dupage, you must increase the MDA by 40 feet.
