Hi Willie, There are plenty of expensive ways to reduce your landing distance, however Mark Langford summed it up perfectly - speed control.
Excuse me I only work in knots, so here are the numbers, 90 mph = 78 knots Stall speed is probably 45knots, so using the conservative rule, approach speed should be 60 knots, and say 55 knots at touch down, the plane has (78/55) squared = 2.02 times as much energy as it would have at 55 knots, so your landing roll will be twice as long as it needs to be. So if you touched down 200 yards in, and stopped in 900 yards, then you needed 700 yards to get rid of all that energy, so land at 55 knots say 65 mph, and you will need 350 yards to slow up = 550 yards total runway.
