Distance Measuring Equipment

Distance measuring equipment dme in aerial navigation equipment for measuring distance by converting the time a special electronic pulse takes to travel from an aircraft to a ground station and for an answering pulse to return.

Distance measuring equipment.

Distance measuring equipment dme is a system that is used in aviation for navigation purposes. When used in connection with a radio range bearing. The interrogator in the aircraft transmits interrogating pulses to the dme station on the ground. Distance measuring equipment operation.

Signals transmitted between an aircraft and a dme ground beacon enable the aircraft to accurately determine its distance from the beacon. Distance measuring equipment dme is defined as a combination of ground and airborne equipment which gives a continuous slant range distance from station readout by measuring time lapse of a signal transmitted by the aircraft to the station and responded back. Operational notes on distance measuring equipment 1. The dme system consists of an interrogator on board an aircraft and a dme station on the ground.

Introduction these notes are a reproduction of a booklet originally 1 1 published by the civil aviation authority knowledge of the aircraft s position is a basic requirement for air navigation and one means of satisfying this requirement is to present the pilot with bearing and distance. The received pulses trigger the dme station to reply. Distance measuring equipment dme is a ground based navigational aid for use by aircraft belonging to our normarc navaids family. Dmes can also provide groundspeed and time to station readouts by differentiation.
