Values for ISA and MSL, at 1805 kg (3979 lb), approach speed 84 KIAS

	Landing distance from 50 ft (15 m) above the	598 m (1962 ft)
	landing surface
	Ground roll	353 m (1158 ft)

NOTE

A landing with a mass between 1805 kg (3979 lb) and 1900 kg (4189 lb) is admissible. It constitutes an abnormal operating procedure.

Performance

WARNING

For a safe landing the available runway length must be at least equal to the landing 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 landing distance.

CAUTION

The figures in the following NOTE are typical values. On wet ground or wet soft grass covered runways the landing distance may become significantly longer than stated below. In any case the pilot must allow for the condition of the runway to ensure a safe landing.

NOTE

For landings on dry, short-cut grass covered runways, the following corrections must be taken into account, compared to paved runways (typical values, see CAUTION above):

-grass up to 5 cm (2 in) long: 10 % increase in landing roll.

-grass 5 to 10 cm (2 to 4 in) long:15 % increase in landing roll.

-grass longer than 10 cm (4 in): at least 25 % increase in landing roll.

Performance

DA 42 NG AFM

NOTE

For wet grass or soft ground, an additional 10% increase in landing roll must be expected.

NOTE

A downhill slope of 2 % (2 m per 100 m or 2 ft per 100 ft) results in an increase in the landing distance of approximately

10 %. The effect on the landing roll can be greater.
