So I can't change it myself by modifying DAT values, can I? I guess no, as long as low power airplanes (Rohrbach Rocco, 168kmh, 1000kW) breaks down to 64kmh *before* touching land, and more modern airplanes (Airbus A300, 913kmh, 13500kW) brakes to 120-150 kmh when landing, reducing to 64kmh in the first tile of runway, walking (crawling) all the runway at 64 kmh, which looks odd and also helps creating those air traffic jams we hate so much... actually that's what irritates me, more than realism or looking fine >:(
Actually, why is it using a fixed coefficient? Couldn't planes land using a linear speed decreasing? From airplane max speed to runway's max speed divided by number of tiles in runway.
