FlightSight is an aviation sight level app. Its purpose is to help pilots determine whether their flight path is above or below distant objects. Position the sight target on cloud tops or bottoms, mountain passes or other aircraft and FlightSight will tell you if the object is higher or lower, and by how many degrees. FlightSight is a low budget HUD (Heads Up Display)! The FlightSight app can be used by holding the iPhone or iPad by hand. Or it can be mounted on the top of the instrument panel. Four display modes can be selected when using FlightSight. Fixed target grid, fixed target grid and fixed level line, floating target grid and floating level line (shown here) or floating target grid only. FlightSight can be used on devices in either vertical (portrait) or horizontal (landscape) positions. Finger gestures can be used to zoom the FlightSight view in or out. FlightSight also has a camera option. When you press the camera button the current image will be saved with all FlightSight information embossed on it. Stop guessing, safe fuel, be safer … use FlightSight! Use of FlightSight is not an FAA approved method or flight path navigation decisions. FlighSight does not replace good pilot judgement and accurate weather reports. FlightSight is simply a tool for helping pilots confirm their flight path decisions.

////// opti-Glide ist kostenlos und benutzerfreundlich ////// opti-Glide ist eine kostenlose App für Segel- und Motorflieger. Sie ist wirklich leicht zu bedienen und konzentriert sich auf die wirklich wichtigen Funktionen während des Fluges. Es werden die aktuellen Lufträume und Flugplätze angezeigt. Die Luftraumdaten stammen vom DAeC und alle anderen Daten von openflightmaps.org. Mit opti-Glide können Sie die Karte stufenlos zoomen, verschieben und drehen. Die Übersichtlichkeit bleibt dabei stets erhalten, weil beim Zoomen automatisch zwischen insgesamt fünf verschiedenen Detailstufen gewechselt wird. Datenkacheln, die auf Wunsch ausgeblendet werden können, zeigen wichtige Daten an. Zum Beispiel die Geschwindigkeit über Grund und die Entfernung sowie Ablage zum Ziel.
