(a) CAA (FAA) Approved Airplane Flight Manual, dated October 18, 1948 (b) Skiplane Supplement. When skis are installed the following supplemented information shall be appended to the Airplane Flight Manual: "Performance Information with Ski Installation: Climb: Skiplane climb performance is essentially equal to that of the landplane. Take-off and landing: Under the most favorable conditions of smooth packed snow temperature approximating 30°F, skiplane take-off distance approximately 20% greater than the landplane distance. 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 take-off and decrease the landing run." (c) When Item 2, 3, 4(a) or 5 propeller is installed, the Airplane Flight Manual shall be revised to reflect this installation under 'Limitations' section and the following statement added under 'Performance' section following Item 4: "5. Performance with the Model _______ propeller has been demonstrated to equal or exceed that presented herein over the altitude and temperature range shown."
