Most of them. In fact, I have not seen an aviation GPS which does not have
this capability. However, the feature is invariably so buried in a bunch of
sub-menus that it is almost useless.

Larry,

Ok, you had your fun jerking my chain, so let's let it go.

Sure.

If you fail to see the usefulness of a moving map display, I can't help you.

That's your inference.

I find the moving-map GPS useful to navigate the KLAX Shoreline
Transition Route. Because ATC demands that you fly directly over the
Pacific shoreline, and it is difficult/impossible to see directly
beneath the aircraft, the GPS display helps. But I wouldn't be
without current paper charts.

Just don't use one!

I was just trying to understand your rationale. I guess you're
unwilling to share anything other than your opinion. Oh well...

All of them. Most if not all the panel mounts will display constant
real time wind direction and speed if you wire in the inputs it needs.
Heading, altitude, etc. Some handhelds can do this but usually you
would just go to the menu and do a one time check of the winds, density
altitude and TAS.

Without a heading information input to the GPS (most handhelds), it
would not seem possible for the GPS to calculate wind speed and
direction. Magic??

Human data entry. Those buttons on the GPS aren't just decoration. They
allow the pilot to pass along useful information to the GPS unit. Like
heading and indicated or true airspeed (I don't know if the aviation GPSs
will do the TAS conversion for you, but there's no reason they
couldn't...you'd just have to enter pressure altitude and temperature as
well).

You type in the info I guess. Heading and airspeed.

Not hardly. Even the panel mounts require manual input. Most of them will
calculate things like pressure altitude and TAS, but you have to dial in all
the info. As I said, it is a pain.

Lot's of head-down time I'd expect. That's not prudent in the LA
basin. But it might be more convenient than an E6B on a long leg out
of town.

What do you need winds aloft information for flying in the LA basin?

Yes, it would be.

All you need to display a wind arrow is an HSI and an Air Data Computer. All
sorts of airplanes have Honeywell KCS-55A compass systems. Shadin has a low
cost ADC.

Combine heading and TAS and strap them into your Garmin 430/530 and it will
display the wind arrow. At least one truly useful time for that information
is on landing. The arrow will show real time wind shear.

Just bring your checkbook. The new Garmin 1000 system in the new Cessna
182/206 will have all that stuff standard. I do know that Garmin is dragging
their heels, kicking and screaming, in upgrading the 430. They should have
never promised an upgrade for that now antiquated system. An upgrade to the
1000 couldn't cost much more. All the engineering talent is going into the
1000 program. The CNX-80 is a BIG white elephant.

Garmin should offer a 1000 trade up program to the 430/530/80 owners that
they couldn't refuse. It would save a lot of headache. It's already going to
cost a mint to get TAWS, traffic, weather, and VNAV approaches on the older
units anyway.
