landable surface question

I am building a seaplane tender ship. I would like to be able to have a landable surface slanting into the water running up to the level opperations deck. So the seaplanes can make a water landing then drop gear & taxi up the slant to the opps deck. Is this possible? For fs2k2. Using FDSDv2. I am hoping to be able to make a player useable craft as well as a scenery .bgl.
