Photos from Winter

Hi Richard

I agree with you - there are other more accurate altimeters. I have two of them.
The problem is that the majority of the instruments in use are the inaccurate
mechanical bellows connected to impossibly complex/fine gear train variety that
have the errors we see on the Winters. I don't know if Winter are any worse than
the average - seem to compare well with the others (PZLs) in my limited experience.

If everybody flies to the same referrence with the same error - we are all
fairly close to having the relative seperation we should have. If some of us are
using accurate instruments and others not then we could have a problem. It's the
same problem they have in applying the reduced vertical seperation is Europe.

So - ignoring salesmanship what do we do? We know they are in common use, and
have a fairly big intrinsic error. As long as the regulations demand a
mechanical ASI and Altimeter we will continue to have the "problem".

Personally - I think the altimeters make smaller errors on average than the
pilots using them. IF the pilot knows the potential error, surely he/she can
compensate.

Bruce, there is more to it.
Rational analysis, yes, but open your eyes. Read what the other users
are saying. 302, no- altimeter is 100 or so times more acurate than
Winter altimeter.....?
Exercise of free speech?. I don't care who is right. I'm a glider
pilot, the end user and not a dealer. After all I really care only for
what is on my panel.
Money invested in selsmanship and marketing do not impress me at all
and I don't think they are improving any of the Winter instruments.

Figured -
Once again we have a demonstration of the difference between rational analysis
and the exercise of free speech.
