l've made an airport and would like to havesome of my aircraft as " static " at it .How do l go about it Thanks replies

Your best bet would be going to the scenery design forum for detailed answers, but a fairly recent technique for adding static aircraft is to write flightplans for the aircraft which have them doing one short flight a week in the middle of the night. The rest of the time they just sit at the airport. You'd have to give them a unique parking spot code and make sure the flightplan is set at 1%. There was a tutorial on this very subject uploaded to AVSIM a few weeks ago if I remember rightly.
