1. Aircraft for 2 hrs and instructor booked for 2.5 hr block. 15-18 min briefing, 12-15 min preflight, 1.5 hr engine run time or block time.
15-18 min taxi and runup.
Leaves 1.2-1.3 flight time with 46-50 min effective training of maneuvers in the practice area.
Then 15-30min debrief and task assignment.
Twice a day.

2. Depends on training big airport location. Only like 15-20 Class B in the entire country which is bigger then Europe.
Besides you can do all if this and stay below Class Bravo as most of it is not down to the surface.
