When you open the app with geotracking enabled and click the location triangle icon, a map appears showing where you are.

What force causes a helicopter to hover in the air?

Helicopters are able to fly due to aerodynamic forces produced when air passes around the airfoil. An airfoil is any surface producing more lift than drag when passing through the air at a suitable angle. Airfoils are most often associated with production of lift.

Can helicopters hover?

The defining characteristic of a helicopter is its ability to hover at any point during a flight. To achieve hovering, a pilot must maintain the aircraft in nearly motionless flight over a reference point at a constant altitude and on a heading (the direction that the front of the helicopter is pointing).
