When using real weather, and already entered the pre-determined sids/stars, what happens if the wind changes upon arrival?
If you selected the STAR option from the SIDS/STARS page, what happens is when you reach the last flightplan waypoint, you will be told a runway to land at, and cleared to finals at your discretion. So if the runway has changed from what you were expecting YOU will have to fly to it.
If however you selected the STAR option "start of star" from the flightplan itself, you will be told to fly the star ST when you reach whatever waypoint you chose. But using this method means you will be vectored to finals when you reach the last waypoint in the flightplan. If the runway has changed you will simply get different vectors.
My second question would be if your not using sids/stars, and just plan a route from A to B in fs fltplan (may or may not change a few waypoints), does PFE keep you on course the whole way? Or does it behave like the fs atc navigation? Meaning, after departure, vectoring you immediately to first waypoint and then "resume own navigation" and creates it's own arrival before last waypoint into IAF.
If you are not using the SID/STARS options you will be told to fly a heading after takeoff, then vectored to the first waypoint. Then told to navigate for yourself. if you go off course it will tell you.
When you reach the last waypoint you get vectored to finals
Not really understanding your last question. How many waypoints in your flightplan, and how many waypoints from the end was your start of star?
