I don't fly a 55 but looking at my Lear 35 manual and I am not sure but I would suspect that the 35 will land in a shorter distance. I get at 6000ft these #s
12000 pound landing weight, zero runway gradient
Actual landing distance 16 degrees C 2955ft
Factored 60% rule 4925ft
This leaves about 1200 lbs of fuel on board and 1 passenger so it would limit you alot. Again this is for a lear 35 not a 55 but I would venture you might be even more limited in it
