To measure airspeed

To calculate altitude

To determine ground speed

To determine radial position from a VOR station.

By receiving signals from VOR ground stations and using the phase difference between the signals to determine the aircraft's radial position relative to the station.

By using GPS satellites to determine the aircraft's position.

By measuring the distance between the aircraft and the VOR ground station.

By analyzing the magnetic field around the aircraft to determine its heading.

The OBS is used to measure the airspeed of the aircraft.

The OBS is used to select and display the desired radial or course.

The OBS is used to control the altitude of the aircraft.

The OBS is used to adjust the volume of the VOR signal.

A VOR and a VOR/DME are the same thing.

A VOR provides only direction information, while a VOR/DME provides both direction and distance information.

A VOR provides both direction and distance information, while a VOR/DME provides only direction information.

A VOR is used for air navigation, while a VOR/DME is used for maritime navigation.

Inaccurate and unreliable navigation, inability to navigate in poor visibility conditions, and incompatibility with other navigation systems.

Limited range and coverage, difficulty in interpreting the instrument readings, and high cost of installation.

Accurate and reliable navigation, ability to navigate in poor visibility conditions, and compatibility with other navigation systems.

Prone to interference and signal distortion, limited availability of VOR stations, and dependence on ground-based infrastructure.
