The "dmg" file offered is a disk image. It contains the "Setup.pkg" installation program.
To "expand" the installation program, simply click the downloaded file.
Thus the "Disk Copy" application, which is part of the Mac OS X, starts to expand your file.
After the file is expanded, please click the "pf40demo.dmg" installation program.
It will merely ask you for the installation volume.
Finally you will find PreFlight in the "/Applications/PFDemo" folder.
Now launch PreFlight and import the scanned map.
In order to import the map, choose the "Miscellaneous - Administration of Maps" menu option.
Thus you open the "Scanned Maps" dialog box.
Here click the "Import..." button,
to open the "Calibration.scm" file (int the "PFDemo"folder).
Subsequently choose "OK", to close the "Scanned Maps" dialog box again.
Thus you have assigned co-ordinates to the image of the map and now you can view or edit your
flight routes on that map.
Note, that because of their higher resolution, the ICAO charts available for
"PreFlight" (on CD) do suit much better for flight planning.
If you no longer need the demo version on your computer, simply remove the "PFDemo" folder.
from 48 30 00 N to 50 30 00 N and
from 6 30 00 E to 9 30 00 E.
Furthermore it isn't possible to safe routes and tracks on disk.
However, the GPS-interface is available to use, so that you can connect your GPS to transfer data.
In "PreFlight" at first choose the "Miscellaneous - GPS Selection..." menu item,
in order to select your GPS.
To read or write flight routes, activate the GRMN/GRMN transmission mode of your GPS,
to record the route flown (track), activate both the NONE/NMEA 0183 (4800 bps) mode
and the simulation mode of your GPS.
SHL wishes you a lot of fun while testing.
