App Makes Perfect Aircraft Holding Patterns a Breeze

A newly released iOS app makes all the calculations that a pilot needs to fly a “perfectly timed” holding pattern. Developed by Aviation Mobile Apps, the Holding Pattern Computer app takes the wind into account when making calculations, allowing pilots to fly an outbound leg that will result in a “neat” intercept of the inbound leg with a standard-rate turn. While other holding pattern apps simply suggest a direct, parallel or teardrop entry, the Holding Pattern Computer also calculates whether to turn left or right, which course and heading to maintain and how long to fly a heading before starting a standard-rate turn. The app also helps pilots remain aware of the aircraft's relative position to the pattern, to magnetic north and to any effects of wind. The hold screen allows users to set the inbound radial, course or bearing of the fix and to select whether the turns in the holding pattern are standard right-hand turns or non-standard left-hand turns. A numeric on-screen keyboard or rotating dial allows pilots to set the inbound leg, as well as to set and change turns and fix type. The app costs $3.99 at the Apple App Store.
