I have watched the thread regarding runaway elevator trim with interest.
My panel was built by Aerotronics in Billings, Montana
(http://www.aerotronics.com/) and I have flown for over 1,000 hours
without any trim issues. However, the photo and sketch diagram below
show a trim cutout switch which Aerotronics included in my panel and
this may be of interest to Europa owners. The switch is 3 position :-
* Up = NORMAL
* Center = OFF
* Down (momentary spring loaded) = EMERGENCY REVERSE
Aerotronics comments about this switch are shown here :-
/.we started doing this after a Glastar crashed when they experienced
a trim runaway. This switch allows you to at least stop the trim if it
were to start to run away and even feather it back to a neutral
position using the momentary reverse position. It an easy thing to
wire up. I dont have a professionally drawn schematic but I quickly
drew it up and scanned it here for you to look at. I drew it two
different ways, they are the same exact wiring just one is drawn
pictorially and one electrically/
If you have difficulty seeing the images on the Matronics link, please
contact me direct. I will be happy to send them to you.
Cheers, John
