Accountants in the sky

The pilot in flight has many devices that work constantly and help him control the plane, especially at night or in the fog.

One of the counters you have is called an altimeter. Indicates how high the plane flies.

Other accountant, called speedometer, indicates the speed at which it flies. In the quadrant, the needle points the direction you are going: north, sure, it is west.

When the plane gains or loses height, a quadrant indicates the incline of ascent or descent.

When the pilot tilts the plane down, another dial tells you the tilt and the turning radius.
