Increase by 10% for each 3 kt (1.5 m/s) tailwind. Increase the ground roll by 10%. 10 cm (3.9 in) long: Grass runway, dry, 25 cm (9.8 in) long: Grass runway, longer than 25 cm (9.8 in): Grass runway, wet: Soft ground: Increase the ground roll by 15%. Increase the ground roll by 25%. A take-off should not be attempt. Increase the dry grass runway distance calculation by 10%. Increase the ground roll by 45% (in addition to the grass runway distance Uphill slope: calculation, if applicable). Increase the ground roll by 9% for each 1% (1 m per 100 m or 1 ft per 100 ft) slope. If brakes are not held while applying power, distances apply where full power setting is complete. Doc. No. 7.01.16-E Rev. 4 02-Oct-2017 Page 5 - 9 Performance Diamond AIRCRAFT DA 42 NG AFM C WARNING For a safe take-off the available runway length must be at least equal to the take-off distance over a 50 ft (15 m) obstacle. WARNING Poor maintenance condition of the airplane, deviation from the given procedures, uneven runway, as well as unfavorable external factors (rain, unfavorable wind conditions, including cross-wind) will increase the take-off distance. CAUTION The factors in the above corrections are typical values. On wet ground or wet soft grass covered runways the take-off roll may become significantly longer than stated above. In any case the pilot must allow for the condition of the runway to ensure a safe take-off. The above corrections for runway slope should be used with caution since published runway slope data is usually the net slope from one end of the runway to the other. Runways may have positions at their length at greater or lesser slopes than published slope, lengthening (or shortening) the take-off roll estimated with these tables. NOTE The effect of 50% of the headwind component and 150% of the tailwind component is already incorporated in the head- and tailwind factors. C Page 5 - 10 Rev. 4 02-Oct-2017 Doc.
