In "Flight mode", the Elevation Graph will display the terrain in front of the aircraft, updating the view every 5 seconds. The maximum reported altitude of the total distance of terrain profile in front of us will be displayed in the graph. We can zoom in or zoom out by using two fingers to see less or more terrain. The scale is displayed in NM. A symbol representing your aircraft will be shown in the view with a red dashed line, representing your current altitude, as reported by the GPS.
