Just like real life, you're not going to get anywhere near enough speed to take off without catapult support.
Here
http://www.simviation.com/fs2004panels4.htm is a panel with meatball/catapult support (the F/A 18 at the bottom of the page) or look for rcbco-11.zip, which contains the gauge and some installation instructions. There are other panels with the same gauge built in just search the library for "meatball".
PS - You are probably going to need to do little panel editing. I don't know of any 2002 panels with this gauge in it.
