All start from parking position with no ground net

Browse source 
Fix for https://sourceforge.net/p/flightgear/codetickets/2125/

Previously, selecting a non-pushback parking position from the l
auncher that did not have a ground network resulted in the
aircraft being placed in the center of the airport.

This resolves the problem by creating a default segment simply
moving forward 2m.
