////// 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.
