3-K-068: Distance Measuring Equipment
3-68K1:
What is the frequency range of the Distance Measuring Equipment (DME) used to indicate an aircraft’s slant range distance to a selected ground-based navigation station?
962 MHz to 1213 MHz.
108.00 MHz to 117.95 MHz.
108.10 MHz to 111.95 MHz.
329.15 MHz to 335.00 MHz.
3-68K2:
The Distance Measuring Equipment (DME) measures the distance from the aircraft to the DME ground station. This is referred to as:
The slant range.
DME bearing.
Glide Slope angle of approach.
Localizer course width.
3-68K3:
The Distance Measuring Equipment (DME) ground station has a built-in delay between reception of an interrogation and transmission of the reply to allow:
Operation at close range.
Someone to answer the call.
The VOR to make a mechanical hook-up.
Clear other traffic for a reply.
3-68K4:
What is the main underlying operating principle of an aircraft’s Distance Measuring Equipment (DME)?
A measurable amount of time is required to send and receive a radio signal through the Earth’s atmosphere.
The difference between the peak values of two DC voltages may be used to determine an aircraft’s distance to another aircraft.
A measurable frequency compression of an AC signal may be used to determine an aircraft’s altitude above the earth.
A phase inversion between two AC voltages may be used to determine an aircraft’s distance to the exit ramp of an airport’s runway.
3-68K5:
What radio navigation aid determines the distance from an aircraft to a selected VORTAC station by measuring the length of time the radio signal takes to travel to and from the station?
Distance Measuring Equipment (DME).
RADAR.
Loran C.
Distance Marking (DM).
3-68K6:
The majority of airborne Distance Measuring Equipment systems automatically tune their transmitter and receiver frequencies to the paired __ / __ channel.
VOR/LOC.
VOR/marker beacon.
Marker beacon/glideslope.
LOC/glideslope.
