That's a motivation to upgrade the G1000 to WAAS. However, I just read
somewhere that the rumor is that the WAAS G1000 systems will not drive
VNAV to the KAP140. So you won't be able to fly fully coupled VNAV
approachs with the KAP140 (even though you can fly a fully coupled ILS
with it).

If an LNAV approach has VNAV minimums will you be able to use DA or will
you have to use the MDA concept?

I don't believe a coupled autopilot is a requirement for the VNAV so I
assume I would be able to fly to DA once the G1000 has WAAS.
