J41 default flight related issues

Tue, 29 Jun 2010 20:48:22 GMT

FSX actually loads whatever aircraft you have set as the default in the background while the sim loads. When the default flight is another complex aircraft (or even a different livery of the same one you're trying to load), it confuses FSX's internal panel state system and can result in numerous strange errors such as but not limited to:

The FMS not turning on
Other aircraft systems not powering up
Engine shutdown after turning the pumps off

To ensure that you have the correct default start up configuration, please check for the following:

If running Windows Vista or Windows 7, Right Click on the FSX Icon and select "Run as Administrator" from the drop down menu. This will ensure that FSX is loaded with proper administrative privileges.
Start FSX and select Free Flight. Check that the default AirCreation Trike ultralight at Friday Harbor is displayed.

If it is not, you need to shut down FSX, open your FSX.cfg file (located at C:\Users\(Your User Name)\AppData\Roaming\Microsoft\FSX in Windows Vista or 7 or C:\Documents and Settings\Application Data\Microsoft\FSX in Windows XP) in Notepad and run a search for "SITUATION" - a line should be found under the [USERINTERFACE] section of the cfg - this is the current default flight. Simply delete this whole line from and save the file. This will reset the default flight to the Trike at Friday Harbor.
Once you have ensured that you have the correct default flight showing in the Free Flight window, you may proceed with loading the J41 from Free Flight by pressing Fly Now, which will load it at the selected airport with the engines running.

From there you can load saved flights from within the sim. (this is due to the FSX quirk mentioned in the manual - do not try to load a saved J41 flight directly from Free Flight, it will cause problems - you must load the sim first)

Taking these steps should solve 99% of the strange issues we've seen reported with the J41. If it doesn't solve your issue, please submit a support ticket.

This issue occurs when FSX SP2 or FSX Acceleration are not installed. The J41 requires one of these to function properly. Either purchase and install the FSX Acceleration expansion pack (which also comes integrated in the FSX Gold Edition) or download and install the FSX SP2 patch.

This can caused by a permissions issue when the installer attempts to copy fonts between FSX and the Windows OS fonts folder.

To solve the issue manually:

Ensure that FSX is not running.
Navigate to the FSX\fonts folder and find the file glassga.ttf.
Open the Control Panel\Fonts applet, and drag the file from the FSX fonts folder into the window, which will install it.
Reboot the computer and run FSX. The issue should be solved.

We've also recieved word that this issue can be caused by disabling the "Distributed Link Tracking Client" service, which is recommended by many popular "tweaking" guides. We highly discourage any disabling of Windows services. The performance gain is negligible at best and at worst you run the risk of causing strange issues such as this one.
