One of the things that was the most challenging learning for me was not shooting an approach nice and relaxed from the IAF with barely another soul on freq. It was on a busy, turbulent, pouring rain, IFR day coming into a class bravo encompassing several airports. Taking machine gun instructions, tight inbound turns, unexpected fixes, rapid descents, etc and dealing with it. In order to simulate that why not throw some quick fire non-standard approaches in on the way out there, especially to unfamiliar airports?
