Electronic horizon?

I just checked their web site. $180 sounded too good to be true. It was.
The AHRS-2 lists for $1200.

Ramy,

Many GPS have a "HSI" page or at least a track derived "compass". These
would probably be easier use that watching the bread-crumb track on a
zoomed-in map. Besides, the track update rate may be much lower than the GPS
update rate in order to conserve internal track memory, though this is
usually user selectable.

Best of all, IMO, is the "panel page" on the Garmin 196 / 296 / 396.

No, and I'm not planning to do so. Our club gliders are all equipped
with needle/ball, and I would be very reluctant to fly over a föhn gap
without.

I've understood this and am glad you succeeded. Just gave you the reason
why course 180 is "recommended". BTW: I don't believe that such a decent
would be successfull in gusty air, at least not reliably so.

I really hope you are correct and I am wrong. I'm not convinced, though.

Knowing the involved company first hand, I'm pretty sure it was a lack
of conversion training.

Glad you like it. But I don't and my club isn't going to install it in
any club glider unless they change the display to a needle.

Stefan

Just be sure to have your T&B on ALL of the time; you will not have
time to turn it on when you need it.

I prefer an aviation GPS with an HSI display.

You wanna get out more. You don't *intend* to go in - it just sort of
happens (p.s. look up 'thermal').

Being inside a cloud does not "just happen". You have to go there, and you
can decide not to go.

Being trapped above a cloud layer under wave conditions is another subject,
though.

Definitely not. If it "just happens" to you, then something is *very*
wrong with your flying tactics and possibly even with your attitude. (It
may "just happen" at night, but I rarely find thermals at night.) In all
real world situations where you might get trapped, there is always
plenty of time to spin up that gyro.

Stefan

Well, it happened to a friend of mine. Lenticular wave clouds can form
with little, or no, warning. I've seen it happen. Of course, you can
believe otherwise and leave your T&B off. And maybe, just maybe, you
will be right.
