Spin vs Flight Breaks

Featured in Flying Magazine July 2012 "8 Great Aviation Apps"! Reviewed favorably on AOPA Flight Planning App Roulette 20 Nov 2012 Designed by an airline pilot, Spin-a-Wind calculates wind components, temperatures, altitudes and airspeeds. The headwind (tailwind) and crosswind components are based on the runway, and reported wind direction and speed. If the airport has parallel runways, using the runway number closest to the actual magnetic heading of the runway gives the most accurate results. The result is also displayed graphically. Crosswind and tailwind components are rounded up, while the headwind component is rounded down, making sure that all results depict the worst case. To instantly change to the opposite (reciprocal) runway, tap the runway number at the far end. Spinning reels are used to make your selections. No keyboard is necessary. Results of calculations are displayed instantly when the last reel stops. The app was designed for one handed use, and ease of operation. The second item on the tab bar links you to a page with temperature conversions. Enter the temperature in degrees Celsius, and instantly the Fahrenheit conversion is displayed, as well as the chill factor in °C and °F using the NWS Wind Chill index used by the U.S. and Canada. (note: the NWS Wind Chill index is not valid for greater than 50°F or less than 3 mph of wind. Relative Humidity and Heat Stress Index are calculated using the entered Dewpoint Temperature. The third item deals with altitudes, metric, pressure altitude and density altitude. Density altitude is diaplayed for assumed dry air, and also moist air (based upon the temp/dewpoint spread entered in the temperature page. The fourth item is the Airspeed Calculator. It uses equations for TAS, mach, and speed of sound. The equations used will be accurate even for the higher speeds of jet aircraft. The fifth item on the tab bar moves the view to the settings page. Here, you can set your display speed units (kts, mph, kph) and pressure units(inHg, hPa, mb) as well as the threshold points where the wind results turn amber (caution zone) and red (aircraft limits).

Flight Breaks is an intuitive and simple way for airline crews or pilots to seamlessly calculate rest periods on augmented international or long-haul flights. The app is designed for airline crews worldwide who need to divide up specific amounts of flight time for determining rest and work periods. Simply set the “Off Time” (take off time), then set the “Flight Time” (duration of flight) as shown on your flight plan, and the “On Time” (land time) is calculated. Additionally, if the “On Time” changes significantly (longer or shorter) due to short cuts or favorable/unfavorable winds, you can change the “On Time” to match the flight computer. This will then in turn alter the flight time and breaks accordingly. Various break options are available depending on how your airline or crew wants to divide up the breaks. The parameters for when the first break starts and when the last break ends are easy to change. There’s even an option for the amount of time in between breaks too! Features include: • Alarms for your specific break with countdown timers until your wake up time. • Share the break schedule with others who have the app by AirDrop or E-mail. You’ll always know how much time remains until your break is over to ensure you’ll be back to the flight deck on time! Flight Breaks. The effortless way for crews to figure out rest breaks.
