I learned mostly under the Seattle Class B, so I think I had more questions about flight limitations and altitude limits to/from the practice area. May depend on what you have in your local area. Some interesting questions would be:
* Can a student pilot request a VFR transition through Class B? If no, why not? If yes, under what conditions?
* Can a student pilot request a Special VFR clearance to land at a towered airport? If no, why not? If yes, under what conditions?
* If weather closes in unexpectedly, and you get back to the airport and find it has a lower visability or ceiling than your student pilot limits allow, what should you do?
* Can a student pilot accept a "LAHSO" clearance to land? If no, why not? If yes, under what conditions? If it is offered by the tower ATC, how should you respond?
* What is different about student pilot visability and ceiling requirments, as compaired to the requirements for a Private Pilot?
* What is your maximum crosswind limit for TO and landing? When landing on RW 33 with wind 270 @ 10, what is the crosswing component? Is it within your limitations?
* If by calculation you determine the crosswind is within your limitations, describe the technique to use for landing. And for TO.
* If you return to the airport for landing and by calculation you determine the crosswind is not within your limitations, describe what you would do to get your aircraft on a runway safely.
* In the prior question, if the only other airport with RW's oriented close to the wind direction is 60 miles away, and you have not been signed off to solo from that airport, what would you do?
And other questions that ask them to deal with potential real situations, and not just quote the "book" information.
