Here’s how to install and get flight planning with the .per files. These .per files should be treated in exactly the same way as the .txt files bundled with PFPX. THEY ARE NOT TEMPLATES – DO NOT PUT THEM INTO THE AircraftTemplates FOLDER. IF YOU DO YOU WILL SEE NOTHING!

  1. Copy the downloaded .per file into your PFPX aircraft folder.
    In Windows 7 the folder is located in C:\Users\Public\Public Documents\PFPX Data\AircraftTypes.
    Alternatively search your computer for Saab 340B.txt one of the default aircraft types bundled with PFPX.I would strongly suggest that you rename each file without the _vX.XX version suffix before you add the aircraft to PFPX. Each update will then overwrite the previous version. The version numbering allows me to track each file and updates easily.
  2. Start PFPX.
  3. From the top menu bar select the Add New Aircraft option in the Aircraft Manager.step2
  4. Select the aircraft type from the Dropdown list.step3
  5. Save!
  6. Weights can be edited and performance adjustments can be made within PFPX to customise the aircraft as required. Note – maximum weights are hard coded into these files. If you can’t change the MTOW to a very high weight that’s the reason. On more recent files the maximum limit coincides with the highest weight for which data is available, with older files it may be the limitation existing on the specific aircraft variant I modelled.
