To enable the carrier, you must edit your preferences.xml file. This lives in your FlightGear data directory, the one under which your Aircraft, Scenery etc directories reside. Open this file in a text editor (such as notepad on Windows, or TextEdit on OSX - Linux users are probably familiar with such software... try kedit or gedit if not.) | To enable the carrier, you must edit your preferences.xml file.

If you are using the Windows or OSX launcher to run FG, you should find a text entry box in the gui that allows you to specify command line options, add the above options there. Linux or Cygwin users can just add them to their usual startup command; ``fgfs --carrier=Nimitz --aircraft=seahawk'. Please note the uppercase ``N' in ``Nimitz'. | If you are using the Windows or OSX launcher to run FG, you should find a text entry box in the gui that allows you to specify command line options, add the above options there.

Once FlightGear has started, you should ensure that the parking brakes are off, ease the plane a little way down the catapult pressing ``L' to engage the launchbar (this might be best done from an external view initially.) You should notice the aircraft being pulled into alignment with the catapult and see the strops appear and hold down the aircraft. This will only happen if your aircraft is close enough to the correct spot on the catapult; as a rough guide, for the default parking position the seahawk's nose should be rougly level with the deck observation bubble. | Once FlightGear has started, you should ensure that the parking brakes are off, ease the plane a little way down the catapult pressing ``L' to engage the launchbar (this might be best done from an external view initially.)

Being engaged to the catapult, you should spool up the engines to full power, ensure the brakes are off and that all flight controls are in a suitable position for launch. When ready, press ``C' to release the catapult. Your aircraft will be hurled forward off the deck, and you should be able to raise the undercarriage and climb slowly away, being careful to avoid stalling. | Being engaged to the catapult, you should spool up the engines to full power, ensure the brakes are off and that all flight controls are in a suitable position for launch.

Actually finding the carrier in a vast expanse of open water can be very difficult, especially if visibility is poor. To assist with this task, the carriers are equipped with TACAN, which allows a suitably-equipped aircraft (Seahawk at present) to obtain a range and bearing to the carrier. First, you must set the appropriate TACAN channel, 029Y in this case, in the radios dialogue (ctrl-r or choose Equipment/Radio Settings from the FG menubar). You should, if within range, notice the DME instrument show your distance from the carrier, and the ADF instrument (next to the DME in the seahawk) should indicate a bearing to the carrier. Turn to the indicated heading and you should see the DME dial indicate your closing in on the carrier. | Actually finding the carrier in a vast expanse of open water can be very difficult, especially if visibility is poor.
