Distance measuring equipment is considered what type of equipment?

Distance Measuring Equipment (DME) is classified as pulse equipment because it operates by emitting radio frequency signals in the form of pulses. These pulses are generated by the DME and sent to the aircraft, which then receives these signals and measures the time it takes for the pulse to travel to and from the ground station. By calculating the time delay of these pulse transmissions, the equipment can determine the distance from the aircraft to the DME station.

This method is fundamental to how DME functions and is a critical aspect of measuring distances accurately in aviation. Pulse equipment typically refers to systems that send discrete bursts of energy, allowing for precise timing and measurement calculations essential for navigation and positioning in aviation contexts.

The other options do not apply in this context: analog equipment typically uses continuously variable signals, digital equipment handles data in discrete values but does not specifically refer to the mechanism of signal transmission in DME, and continuous equipment isn't relevant as DME operates on a pulse basis rather than a constant signal flow.
