Control a Map View, Airport Plan or Simulated Instrument Landing System view to gain full situational awareness of the aircraft you are traveling in. This App uses the Global Positioning System built into your phone along with data about all major airports and navigation systems. You will be able to see which navaid or fix sequence is being used during the flight, and which runway is being used during landing. During landing use Instrument Landing System mode to check how far from the optimal glide slope the aircraft is.
