Subject: [LML] ADAHRS TSO

I am pleased to announce, with a measure of pride, that the Chelton
ADAHRS (formerly Pinpoint) (http://www.cheltonfs.com/EX/specs.html) has
passed all the DO160E test requirements and now has a freshly inked TSO.
The system passed all tests as designed, without failure. DO160 has a
number of different test levels for each of the 25 test categories. Test
levels are determined by the type and application of the equipment
tested. In most cases the ADAHRS was subjected to the highest, most
difficult and most stringent levels. As a result, CFS ADAHRS components
now qualify to be installed in a helicopter's composite  tail boom
operating in environments from -55 to +70 degrees C. Nasty.

This is the first and only ADAHRS to pass the new direct and indirect
lightning tests. Given the design challenges of designing a system that
can survive these tests, I can say with confidence, that no other ADAHRS
currently on the market would be able to pass these tests without redesign.

The attached pictures show the OAT probe before and after the direct
effect lighting test. Despite having 1/16" of  the tip of the probe
vaporized during the simulated lightning strike, both the probe and the
ADAHRS it was attached to continued to operate normally. Lets see your
Timex do that!

The entire ADAHRS design team deserves a "Well done!".

Boasting? Yep, earned it! Planted the seed, harvested the cotton, wove
the fabric, sewed the garment and silk screened the message so now we
"Got the T-shirt".

CFS Press Release to follow.
