I have a 80mm Sage that is in good working order installed in a flying glider. I will sell for $200 and I'll pay the US shipping.

So, I understand a knot is equal to 101.2 feet per minute, is the requirement due to regulations or a non compromising desire for 'the right scale?
I completely understand either, Just wondering.

Geez .. I don't care as long as they have five UP markings and five DOWN markings and I know which is which.

It would not surprise me to learn that the manufacturer writes 1,2,3,4,5 or 2,4,6,8,10 on them without doing anything to change the calibration. I'm pretty sure the positions of the marks is the same. (some of the latter have small halfway marks too, but many don't, even from Winter themselves)

0.97/2 : 1.00 : 1.01 ... who can feel the difference?

Scott,

Normally not a big deal but the flight manual for a Grob Twin clearly asks for a vario in knots.

I've always assumed that using knots for airspeed and ROC was done so
that you can calculate you glide ratio without doing any units
conversion. Once that's done, divide your height by 6000, multiply by
glide ratio and thats your max possible range in NM.

I don't think its that easy if any other units are used for airspeed or
ROC.

Of course, this isn't so important now everybody has GPS navigation
systems that do it for you and draw glide amoebas on the screen.

Is the difference not something that your mechanic can sign off with a
change in the equipment list?
