TE Compensation

[[email protected]]

What is the current thinking on what works better, electric vs. pneumatic TE compensation? I've got an S80 vario which can use either.

IIRC the S80 Manual states that if you have a good pneumatic system you may wish to use it. Read section 5.7.3.9 of the (current) manual. One nice thing about electronic is that you can tune it in flight. You do have to decide during the install because the lines are hooked up differently. If you don't mind the extra work try both and see which works better.
Good article for review here http://www.eglider.org/NewsArticles/totalenergycompensationinpractice.htm

I use my S80 on electronic compensation.
I have my winter on the TE probe.
The two instruments are virtually identical overall.
I prefer flying by the S80 because you can tune it to be less "twitchy".
Completely independent systems means I have solid back-up if I have an electrical failure.

I'm hooked the same way... pneumatic to winter vario, electronic to S80. I like that one 'backs up' the other in case of a failure. It removes the issues associated with splitting TE line to two sources (as covered by a bunch of historical posts), and when you have two independent instruments with independent 'sensors' telling you the same thing, it reinforces the information being delivered. I'm surprised how closely they match up. I have yet to find the need to tweak the electronic compensation, but I suppose that is another reason to have that option if you find it useful.

if you have the static close to the pito and you realy thrust the static => use electrical compensation
If your static are on the sides of the nose => use TE-probe

On my LS1-f is it impossibel to tune the electronical compensation on the S80 to be OK. My guess is that the static is unrealibly and therefore is the electronical compensation imposible.
