## CROSSWIND

Maximum demonstrated crosswind is 24 Kts.

The actual crosswind component can be calculated using a variety of tools such as [AeroToolbox](https://aerotoolbox.com/crosswind/).

## TAKE-OFF

Associated conditions:

1. Power ........................................................................ max continuous
2. Propellers .......................................................................... 2575 RPM
3. Surfaces .......................................... as reported in the relevant table
4. Take-off speed ........................................................ IAS, as tabulated
5. Static take-off ………………….………… full power, before brakes release

#### TAKE-OFF SPEEDS

#### CALCULATION SURCHARGES

**Headwind:** subtract 6% and 4% respectively from the ground and total distances for each 5 knots headwind.

**Tailwind:** add 20% and 15% respectively to the ground and total distances for each 5 knots tailwind.

**Sloped runway:** increase table distances by 8% of the ground distance at Sea Level, 12% of the ground distance at 5000 ft, 16% of the ground distance at 10000 ft for each 1% of upslope. Decrease table distances by 7% of the ground distance at Sea Level, 9% of the ground distance at 5000 ft, and 12% of the ground distance at 10000 ft for each 1% of downslope.

Landing distances on ***grass surface*** have been determined for the following airfield surfaces:

* firm bare soil
* grass up to 5 cm (2 inches) long
* wheel impression up to 1 cm (0.4 in) Different runway conditions may result in improved or degraded performance.
