Spin-a-Wind: A Comprehensive Aviation Utility Tool
Spin-a-Wind is a feature-rich aviation utility tool designed by Leonard Robinson, an airline pilot. This iPhone app is a must-have for pilots and aviation enthusiasts as it provides a range of essential calculations and conversions.
The app calculates wind components, temperatures, altitudes, and airspeeds. It accurately determines headwind (tailwind) and crosswind components based on the runway, reported wind direction, and speed. The results are displayed graphically, offering a clear visual representation. The app also allows for instant switching to the reciprocal runway by tapping the runway number.
Spin-a-Wind features spinning reels that eliminate the need for a keyboard, making it easy to use with one hand. The calculations are displayed instantly when the reels stop, ensuring quick and efficient results.
In addition to wind calculations, the app offers temperature conversions, including Celsius to Fahrenheit, and displays the chill factor using the NWS Wind Chill index. It also provides information on altitudes, including metric, pressure altitude, and density altitude.
Furthermore, the app includes an Airspeed Calculator that accurately calculates True Airspeed (TAS), Mach, and speed of sound. These calculations are suitable even for high-speed jet aircraft.
The settings page allows users to customize display speed units (kts, mph, kph) and pressure units (inHg, hPa, mb). Users can also set threshold points for wind results, turning them amber or red to indicate caution or exceedance of aircraft limits.
Spin-a-Wind is a comprehensive aviation utility tool that offers essential calculations and conversions for pilots. With its user-friendly interface and accurate results, it is a valuable companion for any aviation professional or enthusiast.
