I'm using ProAtc for generating flight plans' I'm saving the route as pln and then importing it into the fmc, I get the origin and destination, when pressing app/dep page I got the departure procedure for the departure, I can select the runway and the sid but when pressing index I get an empty page, what I found out is that I took off and go to the destination' in the middle of the flight the airport on the dep/app page will change from the origin to the destination airport and then I can select the approach procedure
