I am new to the downloading new aircraft thing - I have a Flt Sim 2004 edition and downloaded a couple new aircraft - where do you save them? I opened Flt Sim and they didn't show up in the pull down menu of acft. What is the procedure for saving new data so it shows up in the acft pull down menu when I want to fly them?
You have to extract the contents of the .zip file you downloaded. Extract to a Temporary folder. Now you can look for the Readme file and Installation instructions.
