WindCalc is a simple program for Palm OS devices that calculates the headwind or tailwind component and crosswind component for a given wind condition and runway.
It replaces the crosswind component chart that pilots generally use and makes the calculations simpler, quicker and more accurate.
WindCalc 2.2 uses slider controls to change the values of the wind direction and speed. The numbers and asterisks above and below the sliders can be tapped to quickly input a value. Above the wind direction slider the numbers and asterisks are separated by a value of 30 degrees while the numbers and asterisks below the wind speed slider are separated by a value of 5 knots.
The pushbuttons at the top of the screen are used to change the value by which the wind direction will jump when you tap the slider background on either side of the slider thumb. You can have the wind direction jump by either 1, 5, or 10 degrees.
A single tap on either the wind direction field or wind speed field will select and highlight the number automatically so that you can immediately enter a new number for that field in the graffiti area.
