Remember high to low down you go, so sometimes terrain can be with in your MSA...thus making the transition level higher...thus making the quadrant you are flying have a few less FL's available.
gcolyer,
Have pity on the poor chap/chapess. He/she has just started the PPL; do you really think he'll follow that? I'm an instructor and I had to read it three times.
TIMZ,
Madhouse is right, but there are ways through it.
1) If you've been reading PPRuNe, you may know who you can trust to write sense.
2) Look at the person's profile. Chilli Monster is an ATCO, so he knows about this sort of stuff - he has to. And quite a few instructors read this forum. I'm not saying all the PPLs don't know their stuff...but....some don't.
3) Ask for clarification if someone tells you "high to low down you go", and you have no idea what they're talking about. We won't mind; we've all been there.
4) Compare what you read with the book and see if it makes sense.
You don't really need groundschool for Air Law; it's mainly rote learning. But if you think you do, I'm sure someone can manage it. Where exactly are you based?
