SR20 Performance Data
Landing Distance
Factors:
The following factors are to be applied to the computed landing
distance for the noted condition:
• Headwind - Subtract 10% from table distances for each 13
knots headwind
• Tailwind - Add 10% to table distances for each 2 knots tailwind
up to 10 knots.
• Grass Runway, Dry - Add 20% to ground roll distance.
• Grass Runway, Wet - Add 60% to ground roll distance.
• Sloped Runway - Increase table distances by 27% of the
ground roll distance for each 1% of downslope. Decrease table
distances by 9% of the ground roll distance for each 1% of
upslope.
• 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) landing
ground roll estimated from the table.
• 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:
• Technique .............................. Normal Outside Air Temp........................10°C
• Winds ..........................................Zero Weight .................................. 2900 LB
• Runway .................................... Paved Pressure Altitude .................. 2000 FT
• Flaps. ........................................ 100% Headwind ................................... Zero
• Power .................. 3° Power Approach
to 50 FT obstacle, then reduce power Landing Ground Roll ............ 1072 FT
passing the estimated 50 foot point Dist. over 50' Obstacle.......... 2116 FT
and smoothly continue power
reduction to reach idle just prior to
touchdown.
