Thanks to everyone for their help, I wound up creating a set of flash cards with:
* Aircraft Name
* ICAO
* Wake Turbulence Category
* Cruise Speed
* Cruise Level
* Climb Rate to FL150
* Descent Rate to FL100
I’ve stuck to the same ~50 aircraft as the NATS pack. I think that should be a decent start and isn’t bad information to know regardless of my eventual rating.
Enjoying how the rest of the discussion has turned out in this thread. I’m hoping for an area rating at CTC (I was told I was too tall to go to Gloucester) but I know it could go either way.
