Takeoff Distance
Factors:
The following factors are to be applied to the computed takeoff
distance for the noted condition:
• Headwind - Subtract 10% from distance for each 12 knots
headwind
• Tailwind - Add 10% for each 2 knots tailwind up to 10 knots.
• Grass Runway, Dry - Add 20% to ground roll distance.
• Grass Runway, Wet - Add 30% to ground roll distance.
• Sloped Runway - Increase table distances by 22% of the
ground roll distance at Sea Level, 30% of the ground roll
distance at 5000 ft, 43% of the ground roll distance at 10,000 ft
for each 1% of upslope. Decrease table distances by 7% of the
ground roll distance at Sea Level, 10% of the ground roll
distance at 5000 ft, and 14% of the ground roll distance at
10,000 ft for each 1% of downslope.
• Caution •
The above corrections for runway slope are required to be
included herein. These corrections should be used with
caution since published runway slope data is usually the net
slope from one end of the runway to the other. Many runways
will have portions of their length at greater or lesser slopes
than the published slope, lengthening (or shortening) takeoff
ground roll estimated from the table.
• If brakes are not held while applying power, distances apply
from point where full throttle and mixture setting is complete.
• For operation in outside air temperatures colder than this table
provides, use coldest data shown.
• For operation in outside air temperatures warmer than this table
provides, use extreme caution.
Conditions: Example:
• Winds.......................................... Zero Outside Air Temp ....................... 25°C
• Runway................... Dry, Level, Paved Weight...................................3000 LB
• Flaps........................................... 50% Pressure Altitude...................2000 FT
• Power.................................. Maximum Headwind ............................. 12 Knots
set before brake release Runway ............................. Dry, Paved
