Welcome sir.
firstly, press ALT , then in the flight simulator, look up u will see a bar, search for the Word "World" then press it and look for Map, u will see your plane and your place from the world, press on the airport u want to land, u will have the rwy numbers and the rwy FREQ and Course copy them in paper, and Have a nice landing :)
If the aircraft is pro like PSS or PMDG , no need for all these stepd, simply , go to the FMC, NAV then u will see the FREQ and the Course, press on them 2 times.
Regards..
Mohammed Yasir
