DME Flashcards
(10 cards)
DME
Distance Measuring Equipment
does MGA have DME
no
what frequency do DMEs use
962 - 1213 MHz (Ultra High Frequency)
what is it normally tuned with
it is normally tuned automatically with a paired VHF station (VOR/LOC)
what does the airborne DME transmit
an interrogation signal
what does the ground DME faculty do
received and replies to the interrogation
what does the airborne unit calculate
the airborne unit calculates SLANT RANGE distance to the station based on relay time
due to slant range error…
when flying over plead the station, DME indicates greater than zero
when is slant range error negligible
slant range error is negligible at 1 NM DME station per every 1000’ height
ex: at 5000’, slant range is negligible when FURTHER than 5 NM of the station
draw DME station volumes
