Chapter 11, Distance Measuring Equipment Flashcards
DME is based on what type of radar?
Secondary
DME provides the following information to
the crew
Distance to a navigation aid
When tuned into a VORTAC, commercial
aircraft obtain their distance and bearing
information from the
TACAN and VOR
DME signals are transmitted
By line of sight
An RDMI provides the following
information
Distance and bearing to a navigation
aid
Slant range errors are greatest when the
aircraft is flying at
High altitudes and close to the navigation
aid
To select a co-located VOR-DME navigation
aid, the crew tunes into the
VOR frequency
The DME interrogator is part of the
Airborne equipment
The varying interval between pulse-pairs
ensures that the interrogator
Recognises its own pulse-pairs and rejects
other signals
When a DME indicator is receiving no
computed data, it will display
Dashes
Using a collocated VOR–DME navigation aid
produces what type of position fix?
Rho–theta
Distance and bearing signals from a TACAN
navigation aid are transmitted on
UHF
Using two DME navigation aids provides how
many calculated positions?
Two
DME operates in which frequency band?
UHF
