<<Pilot-student (obviously following the CFI instructions)
or CFI: "Request permission to land runway xx"
FIS: "permission granted, you can land runway xx.">>
That sounds like the kind of R/T one reads in a comic. Do they really behave like that?
Not exacly. At some busy not controled GA airports You call FIS and ask for situation on the airport. FIS told you runway in use, circle pattern, how many planes is at the traffic pattern and ask you to call on a position like downwind or final... If you are on final You told to FIS - final full stop, or final t/g. Then FIS give you wind information and granted to land, what give you information that runway is clear. But it is only information for You. You don't have to following the instructions.
