Lots more to the workload: radios and frequencies, and figuring out what to repeat back and what not to is gonna take some experience. I hope the controllers weren’t laughing too hard….
So far, up ’til now, I have done all my work at untowered (pilot controlled) airports, with one class D once as a touch and go.
I’m thinking it woulda been easier to start at a class C and go down to untowered places, rather than work up.
I’ll get it, just more to learn.
Onward and upwards, as they say.
