when I soloed people, I had to make sure that if the airport ''closed'' while they were soloing, they had at least one other option they were familiar with.
when I was teaching it was below the TCA (now called b) and they had to have a full understanding of where they were and where they could not go.
when I was checking out people who had never been to this particular airfield, it took them a couple of hours to understand what they needed to in order to fly safely at that field.
So it takes longer at certain places than at other places. Some planes have more technical things too that you must be aware of rather than the super simple planes of yesteryear (think cub).
So, it takes you what it TAKES YOU at the field , with the plane and the weather you are dealt.
Don't worry about it unless you get well past 30 hours of dual.
I had one student who flew fine, but his primary language was Japanese and his problem was understanding the radio in english. So he became very frustrated. well, that's fliife ;-)
