GPS questions

And some of 'em you don't even need to be scud running to hit. Those danged
things are thousands of feet tall around here!

Flatlander!

Jay, I've flown with the terrain feature of a GPS. It is a complete waste
of money for a VFR pilot. It's even useless out here where we actually
have terrain. If where you fly there is a lot of antennas and you often
scud run and are dodging these antennas then an obstruction database may
be of some use.

Last I heard the tallest man made structure was the TV antenna between
Fargo and Grand Forks at 2000 AGL. The vast majority of antennas are
much less than 1000.

Back in the 70's they built towers between Des Moines and Ames that were
2000 agl (2998msl). Looking at a Chicago sectional shows several antennae
around 1500-2000 agl in Jay's neighborhood.

Just south of Sacramento, there is a cluster of four 2000-footers (The
southernmost two are 2049.) They're in the delta, so their absolute
height is the same as their AGL height. We've also got a 1500-footer
on top of a 3000-foot ridge between San Jose and Watsonville.

Otherwise, yes.

Really? What price are they quoting now for terrain?

Less than $100 on a near $200 item. Your acquisition price was
unbeatable and definitely "show" only...

If it gets cheap enough, I may actually spring for it. (Even living in
Iowa! :-)

Got at least a half a dozen towers near 2000' within 50 miles of me. Our
Airmap 1000 always showed the older ones, some updates didn't catch the
newest ones. Course it never warned you about hitting them...

I took some pics of the one on the ridge between Watsonville and
South County awhile back.

Those ones in the delta are pretty impressive too. At least they
are painted in high visability colors. The one on the ridge is
flat grey.
