5 Performance<br />
5.2 Take-Off Distance Effected by External<br />
Circumstances<br />
Determined data apply for ISA conditions and a dry, hard runway<br />
surface. Various circumstances have an effect on take-off and<br />
landing performance. According to ICAO-circular 601AN/55/2 it is<br />
recommended to use following add-ons on roll- and air distances:<br />
Description<br />
On roll distance for dry grass +20%<br />
On roll distance for wet grass +30%<br />
On roll distance for soft surface +50%<br />
On roll distance for high temperatures +10%<br />
On air distance for dirty wings/raindrops +15%<br />
On air distance per 2 knots tailwind +10%<br />
On air distance per 10 knots headwind -10%<br />
On air distance for high temperatures +10%<br />
On roll distance above sea level (density altitude)<br />
On air distance above sea level (density altitude)<br />
+5% / 1.000ft<br />
+5% / 1.000ft<br />
Comment:<br />
Flight performances can vary significantly due to tolerances of<br />
propeller and engine, flights without doors, deviations from<br />
temperature and air density from standard ISA conditions, etc.<br />
