It's worth the bucks because it can save your bacon. Using some type of AOA
is the ONLY way you can be sure when the a/c is about to stall (has anyone
out there felt airframe buffet during a base to final turn and lived to tell
about it?), and the PSS "device" has no moving parts which made my decision
to buy it rather easy.

Being a relatively inexperienced pilot, I've never come across an AOA sensor
before, just a stall warner on the cherokees & cessna's I learned in. I've
looked at the web site but what are forum members experiences of this
equipment, is it worth the bucks and can I get one in the UK?

PSS' website is http://www.angle-of-attack.com. The Sport costs $890, the
Professional $1500.
The major difference is in the display, and most purchasers ( according to
the company ) buy the
Sport, since it gives the same information, including synthesized voice
warnings, and it's a whole
lot smaller so it fits on the glareshield better. The Pro has a digital AOA
readout and a more
complicated display.
The last time I checked with PSS they would sell you the sensor alone for
$450. I'm not sure if
you pay a bit more in total to split your order this way.
Has anyone out there used larger I.D. pneumatic tubing for their
Pitot-Static runs than the standard
1/4" OD 1/8" ID supplied?
