I think it is worth reminding users* ESPECIALLY clubs* re negative TE setings. "100" is for not using TE probe (ie ele compensation) and "0" TE compensation. If for some reason you during flight decide you would like something negative for TE then when 302 is restarted it will give problems like all but useless TE. If you as pilot use a negative number you should restore TE to zero so as when the next pilot who comes along and does not check the TE setting (ie left in -ve) will not get totally frustrated. If you feel the TE is not perfect then maybe check plumbing as I have seen a partly blocked TE line causing real problems with 302 vario especially with a Winter mechanical in the system. Talk to me if you wish to do a simple test for partly blocked TE line.
Please try and discourage people fiddling with the TE and if they are a fiddler then remind them about the -ve TE issue. And while on varios the CNvario does have G sensing in various axis and a magnetometer but these are not in use with current versions. Their use is down the track and hopefully will be an improvement in gust dampening in varios in the future. Also just a reminder a partly blocked Pitot line will cause the mech ASI to read something like 80 or 90 kts on tow (ie climb) and on decent and landing read 20kts or even zero kts (esp with airbrakes out). Suggest all put this in their mind OR when in doubt look at horizon as that never lies!!! Thats all Ian McPhee 0428847642t.
