Garmin 530 WAAS?

That may be. But that article links to a Garmin document, which
states in part,

"...The Service Bulletin and SAIB notifications will not prevent the
pilot from flying GPS approaches including LNAV/VNAV and LPV
procedures..."

My point exactly.

content. Pilots will also experience significantly enhanced functionality
because of the WAAS LPV, LNAV/VNAV, LNAV+V, and LNAV approach capabilities.

Coupled procedure turns and holds? Why is WAAS an enabling factor for
that?

Thats pretty interesting. Go missed and hold. I'll just take a little
break :-)

I don't read where he said WAAS is the enabling factor for track-guided
procedure turns or holding patterns.

How are they going to provide outbound guidance in a hold, and make proper
allowance for wind, while allowing a standard rate turn to inbound?

With ordinary approach certified GPS.

I don't have any idea how they plan to do it. The previous posting is
the first I've heard of it.

I do know that the high-end stuff had done track-guidance holding
patterns for years, but there is no direct relationship to FAA patterns.
But, no one has ever picked the nit about the differences.

So how does ordinary approach certified GPS do it? None of those I have
used do it.

The 430/530 didn't provide hold guidance prior to the upgrade. The point he was trying to make is that
this feature is part of the same upgrade package, but not specifically related to WAAS. As Sam said, the
big-boy FMSs have provided hold and procedure turn guidance for years, using just VOR/DME or
DME/DME position updating.

But my question is how do they do it? The desired track in a hold is not
the pretty little racetrack pattern with two parallel sides and two
semicircles at each end, except in a no-wind situation. The desired track
on the outbound leg is that which will put you in a position from which a
standard rate turn will roll you out on the inbound track That is why we
fly outbound with a multiple of the inbound wind correction.. The GPS box
cannot do that without knowledge of the wind. A fancy FMS which determines
the wind correction from the autopilot can do that, but how can a standalone
GPS box, WAAS or not, do that?

But my question is how do they do it?

I don't know how they do it. (and true, the 430 doesn't alter the hold
track for wind, though it does for airspeed). There's no reason it
couldn't though - WAAS has nothing to do with it. As long as you know
heading, airspeed, groundspeed, and track, the rest is just math.
