POH takeoff distance tables — 600 kg, dry runway

Takeoff correction factors (from POH)

Factor	Correction
Headwind	Subtract 10% per 12 kts headwind
Tailwind	Add 10% per 2 kts tailwind (max 10 kts)
Wet grass	Add 18% to ground roll on dry grass
Upslope	Add 22% of SL ground roll per 1% upslope
Downslope	Subtract 7% of SL ground roll per 1% downslope

Source — POH Section 5.6. MTOP must be limited to 90 seconds.

POH landing distance tables — 600 kg, dry runway

Landing correction factors (from POH)

Factor	Correction
Headwind	Subtract 10% per 13 kts headwind
Tailwind	Add 10% per 2 kts tailwind (max 10 kts)
Wet grass	Add 30% to ground roll on dry grass
Downslope	Add 27% of ground roll per 1% downslope
Upslope	Subtract 9% of ground roll per 1% upslope

Slope corrections should be used with caution — published slope is usually the net slope from one end to the other. Many runways have portions at greater or lesser slopes.
