Sky View is a fun but useful part of the app that allows you to take a look at airports from a birds eye view. Reviewing an airport prior to arrival can help with surveying the area to become familiar with the airfield and visual aspects surrounding it.
Enter an airport code (ICAO, IATA, FAA) and search for your airport. You can also tap the button with the aircraft symbol to locate the airport nearest you and display the map of this airport. Use pinch to zoom as desired to zoom in or out of the airfield.
