 Posted: Tue Apr 07, 2009 2:59 pm Post subject: Trio altitude hold system |
 |
|
Hi all,
Maybe one of you has come across the same problem that I have encountered. I
have purchased a Trio Altitude hold and can not get it to hold the altitude
at all. Upon engaging the systems starts initiating a ever increasing
proposing of the airplane with variations in altitude over 500 feet on
either side. We have tied different approaches wit the help of the technical
experts at Trio but have not come up with a solution. I have reset the
system on numerous occasions, have shut down everything electrical in flight
except the mags, have removed the strobe lights, have taken the adjuster and
LED indicator out of the panel to eliminate interference and have replaced
the electronic controller and the servo with new ones, without success.
Maybe somebody can help

Hi Franz
Have you checked for play in the linkage between the servo arm and the
control mechanism, or more generally, any play between the servo and
elevator?
Control systems usually exhibit the symptom you describe if there's
backlash or play...

Or if the servo is not fast enough to stop the natural plungoid pitch
cycle and makes it divergent. We have the same issue in Glasairs with
STEC AP's the servo is too slow and the aircraft just keeps pitching
up/down in ever increasing cycles. The cure is to increase the servo
response time. In an STEC it means changing out a resistor, I don't know
how it's done on the Trio.

This was my first area of checking, all is very solid, probably over build, I also tried out the system without connecting the static line, no change as well

I must have missed the beginning of the thread...but whoever started it -
stop typing, pick up the phone and call Trio.
Their support is top-shelf and I'm sure there is a quick and simple fix for
your application (dead-band and gain settings). In my opinion, you are
simply wasting time on the forums for this kind of issue...go to the source.

Good advice, but useless. I have been talking to them for the last three
months, they can not figure it out,
