If two DME ranges are plotted on the chart and used to fix the aircraft position, what would be indicated on the chart?
  • A
    Two circular position lines intersecting at two points, the distance from each transmitter being the plan range.
  • B
    Two straight lines intersecting at one point, the distance from each transmitter being the slant range.
  • C
    Two circular position lines intersecting at two points, the distance from each transmitter being the slant range.
  • D
    Two straight lines intersecting at one point, the distance from each transmitter being the plan range.

Refer to figure.

The DME displays distance information from a fix. This distance being the slant range between the transmitter and the aircraft. The position of the aircraft may be anywhere on a circle with the DME in the centre, with a radius that is the range from the DME. Two overlapping circles will intersect at two points.
