Here is a wind speed puzzle. Your course is due north, 000 degrees. That is you will proceed in a straight line over the ground to a point that is due north of where you are now. The wind is blowing from 100 degrees, that is from mostly off your right wing, but slightly behind you. With no wind at all, your groundspeed would be 100 knots. Will your groundspeed in the described conditions be greater or less than 100 kts?
My answer and why I mention it, in a couple of days. And as usual, if you know you know, give the student pilots a chance to answer first.
Also, I stood on the wing to fuel tonight, then as I slid off the leading edge holding the fuel nozzle I managed to bash my leg on a nacelle fairing. A customer watched me do it, and I was telling him the truth when I smiled and said I was fine, but I have a really amazing colourful bruise on my leg now.
