All right, seriously now ... how many of you who own a watch with a slide rule actually use it ... 1. While flying ....2. Ever, at all
I bought that Breitling watch off the guy that had it on ebay, yeah it's a ripoff but I paid next to nothing for it. It doesn't work properly - but the slide rule works.
It's so damn heavy though, why wouldn't you just have a flight calculator handy ... at 1/50th the weight!?
So seriously ... how many of you have found yourself flying with your knees while peering at the tiny numbers on the dial trying to work out your fuel burn?
