Quite possibly the most inappropriate new hobby

... for someone who is forever going on about reducing her CO2 emissions, is ... drum roll....

... learning to fly.

First theory lesson was tonight. We're doing Meteorology first, so we started with the hard stuff - Environmental Lapse Rate, Dry and Saturated Adiabatic Lapse Rates, and Dew Point and Relative Humidity, and how some jiggery pokery with all of them tells you how high up the clouds are going to form and how unstable the weather's going to be.

The Met theory book (Weather to Fly, hur hur) is about a centimetre thick, and has lots of juicy graphs and charts. I'm already geeking out on it a bit... I like that feeling when something which was previously gobbledygook to me becomes sense. Like this (a Creative Commons image):

There are six of us in the class - me, Dad (hi Dad!), Alan who didn't say anything at all, Ryan who is about fifteen and had to leave early because he's still on his restricted drivers' licence, Matt who is Australian and has already done the Law module and is looking for a plane to buy, and Sina who didn't say anything either. I hope we get a bit more discussion later.

I also proved (yet again) that I suck at navigation; missed the offramp on the way out, and two turns on the way home. Can't wait to see how bad I am when I'm navigating in 3D rather than 2D.

Must book a practical lesson soon. Go see these cloud formations for myself.
