Spin-a-Wind

Spin-a-Wind


This application is a pilot's tool. It easily breaks down the runway wind into headwind and crosswind components. Pages are also available to convert temperature from celsius to fahrenheit, calculate windchill factor, heat index, pressure altitude, density altitude, for both moist and dry air, true airspeed (TAS) mach number and speed of sound. It's easy to use with spinning reels to input data, which is instantly calculated and displayed.
The calculator enhances, but legally cannot replace your approved paper charts and E6B -- for takeoff and landing, your legal performance procedures must be used. But, if the winds are strong, you can refine your calculations with Spin-a-Wind!

Some notes on Spin-a-Wind:
- For wind calculations, all values are rounded to the most conservative value, rounded up for crosswinds and tailwinds, and rounded down for headwinds. For instance, if the tailwind calculated to 9.1, then 10 will be displayed. If the headwind calculated to 5.8, then 5 will be displayed.

If you are testing for zero in the altitude page, then understand that standard day, the pressure is actually 29.921 inches of mercury or 1013.2mb or hPa., so the calculator will not read zero altitude for 29.92 inHg or 1013 mb.

Good App With One Very Annoying Feature This is a pretty good app, but could be better. As others have observed, single digit runway numbers should be preceded with a zero. The most annoying part of this app, however, is the NAG screen that opens every time you start the app, warning you with a DISCLAIMER that THIS APP IS NOT APPROVED by the FAA. Developer: PLEASE get rid of this annoying warning! Make us acknowledge that we understand it, click to agree, then get rid of it already!

Easy to use I'm a commercial pilot and use the app to visualize the crosswinds. Simple but works! Thanks

Easy to use Add a temperature setting all in °C. Runway headings should have leading zero Rwy8=>Rwy08
