Headwind shortens Takeo and Landing runway length by 8 meters (25 feet) with every 5 km/h
(3 kts) of wind increase (e.g. provided there is a 10 km/h (6 kts) headwind on takeo and landing, dis-
tances will be approximately 16 meters (50 feet) shorter then ones published in the manual).
Tailwind prolongs Takeo and Landing runway length by 18-20 meters (60-65 feet) with every 5
km/h (3kts) wind increase (e.g. provided there is a 10 km/h (6kts) tailwind on takeo and landing, dis-
tances will be approximately 36-40 meters (120-130 feet) longer then ones published in the manual).
WARNING! Tailwind aects takeo and landing performance by more than twice as much as
headwind does.
The table below provides data about the eect of headwind (+) and tailwind (-) on takeo runway
length.
