Also the practical test in itself really depends on the examiner. Each test can be different, but they do have the practical test standards to follow. Mine was talking about 121 FAR's, flight principals from the AIM, wx in general, wx patterns, wx theory and a lot of wx charts. Then I had to build up a flight plan with all the performance manuals, paper Jepp approach plates and enroute charts…etc with manual weight and balance numbers and then explain why I chose this and that.
When they give you the flight plan, you will most likley have some sort of restricting MEL item, most likely be from an airport with a short runway, will have to pick an alternate, and work around any possible weather.
Remember though, the examiner is NOT there to fail you! They just want to see your thought process, and decision making while making sure you have a general understanding for the material. If you don’t know something, just say I don’t know. No shame in not knowing because you simply can not know everything. The key is knowing where to look up the subject matter. If you don’t know an FAR, MEL, WX chart info ...etc, know where to look it up.
