For a couple of examples, the Cirrus SR22T manual recommends 80-85 knots on final, and 79 knots crossing the threshold. Category C: Between 121 and 140 knots. This briefing note discusses the factors which go to the calculation of final approach speed. Using these assumptions, one may calculate that an aircraft originally requiring landing distance of 4000 feet (1210 meters) could, by flying an approach 10 knots too fast onto a wet runway and crossing the threshold 20 feet too high, need 4900 feet (about 1500 meters). Tc. 0000189055 00000 n 160 Multiply that by the square root of the actual landing weight over the max gross weight and you'll get the 1.3 Vso CAS at the landing weight. 0000190628 00000 n 50 0000190457 00000 n Add a late touchdown too and required landing distance may almost double.
