AQP varies from airline to airline. At my previous job AQP was once a year for everyone, with two sim sessions on consecutive days. Sim 1 was maneuver validation, basically practicing lots of v1 cuts, and all kinds of ILS approaches with missed approaches and a landing here and there, stalls, and unusual attitude recoveries. Sim 2 was a LOFT and practicing a couple more things. It was a very neat program.
