"PERFORMANCE WITH SKIS INSTALLED Takeoff and Landing: Under the most favorable conditions of smooth packed snow at temperatures approximately 30°F. skiplane takeoff distance is approximately 10 percent greater than the distance shown for the landplane. Skiplane landing distance is approximately 20 percent greater than that shown for the landplane. In applying the performance data, caution should be exercised in that lower temperatures or other snow conditions will increase the ski friction and hence increase the takeoff run and either increase or decrease the landing run. Climb Performance: The skiplane rate of climb is approximately 50 feet per minute less than the landplane."
