Mega App für Piloten

Warum ich 5 Sterne vergebe? Weil es 6 nicht gibt!😁
Diese App ist ganz hervorragend. Der Entwickler ist selber Pilot und hat diese App mit dafür angepasst. Für jeden Flugplatz kann man sich direkt Beginn und Ende der Bürgerlichen Dämmerung anzeigen lassen, für jeden Tag. Somit für Fluglehrer zum Erstellen von Flugdurchführungsplänen bzw. auch Flugaufträge mega. Damit ist man auf der sicheren Seite als Pilot.
Seit SERA ein muss für Piloten. Ich empfehle die jedem Schüler und auch meinen Fluglehrerschülern weiter.
Danke Vielmals an den Entwickler!

FAQ

What kind of information does Sun Facts provide?

Sun Facts calculates times for sunrise, sunset, solar noon, various twilight periods (civil, nautical, astronomical), blue hour, and golden hour. It also provides the equation of time, solar declination, and the sun's azimuth and altitude at noon.

How does the app determine my location?

The app can determine your location using your device's GPS receiver. Alternatively, you can select a location from a map or choose from a list of over 30,000 cities. You can also manually input WGS-84 coordinates.

What features are included in the Pro Version?

The Pro Version, available via in-app purchase, unlocks detailed moon information including moonrise, moon transit, and moonset times. It also provides moon declination, azimuth, altitude during transit, and notifications for upcoming new/full moons and lunar eclipses.

Can I see the sun's path with this app?

Yes, the app offers a feature to visualize the sun's path during the day. This can be particularly useful for photographers planning shots or for understanding the sun's movement throughout the day.

Is there a way to quickly see sunrise and sunset times?

Yes, the app includes a widget that can be displayed on your device's Today screen. This widget provides at-a-glance information for sunrise and sunset times without needing to open the main application.
