The USAF began using GPS as far
back as Dec. 1973, but the civilian pilot community is still wrestling
with GPS issues such as accuracy, availability, redundancy, and
integrity to this day. AOPA conducted a study that indicated flying on
GPS w/o autopilot actually resulted in two to four times *greater*
cockpit workload. ... pilots flying via GPS with
out-of-date databases (they're supposed to be updated every
28 days for IFR use), and the list goes on and on...


I dunno. I fly without an autopilot, sometimes with a GPS and
sometimes without. I simply don't believe that the GPS doubles
my total workload. I'm SURE it doesn't double my workload

Could you please provide a reference to this AOPA study? I have
a hard time believing it exists .... this sounds much more like urban
legend than actual fact. I'll be happy to rectact the last sentence if
I'm wrong.
