I've always had a TAS ASI, and I've never had a problem setting it
correctly. Are you guy sure you don't need you glasses prescription
tweaked a little?

I've always had one, too. In over 800 hours (plus another 400 with Mary as
PIC) I've never set it.

Not even once.

It is a waste of money. Not a LOT of money, in aviation terms, but still.
