→Genapts: No need to unpack apt.dat.gz
You can do two things now:
*'''Already-made airports:''' Locate FlightGears <tt>apt.dat.gz</tt> file, which is usually in <tt>[[$FG ROOT]]/Airports/</tt> in the just created directory
. Unpack the file before you continue.
*'''Home-made airports:''' if you created an airport in [[TaxiDraw]], just use the .dat file that you exported.
