SR20 Performance Data

Cruise Conditions:

• Total distance ................................................560 Nautical Miles

• Pressure altitude ........................................................6500 Feet

• Temperature ...............................................20° C (ISA + 17° C)

• Expected wind enroute..................................10 Knot Headwind

Landing Conditions:

• Field pressure altitude ................................................ 2000 Feet

• Temperature ...............................................20° C (ISA + 10° C)

• Field length................................................................. 3000 Feet

Takeoff

The takeoff distance tables, Figure 5-9, show the takeoff ground roll

and horizontal distance to reach 50 feet above ground level. The

distances shown are based on the short field technique.

Conservative distances can be established by reading the tables at the

next higher value of weight, altitude and temperature. For example, in

this particular sample problem, the takeoff distance information

presented for a weight of 3000 pounds, takeoff field pressure altitude

of 2000 feet, and a temperature of 30° C should be used. Using the

conservative values results in the following:

• Ground roll ................................................................. 1940 Feet

• Total distance to clear a 50-foot obstacle ................... 2734 Feet

Since the takeoff distance tables are based upon a zero wind

conditions, a correction for the effect of winds must be made. Use the

wind components chart, Figure 5-8 to determine the crosswind and

the headwind (or tailwind) component of the reported winds.

Using the 11-knot headwind component, the following corrections can

be made:

• Correction for headwind (10% for each 12 knots) ..............9.2%

• Ground roll, zero wind ................................................. 1940 feet

• Decrease in ground roll (1940 feet x 0.092) .................. 178 feet

• Corrected ground roll................................................... 1762 feet

• Total distance to clear a 50-foot obstacle, zero wind... 2734 feet
