Rev Test 11 Flashcards

The distance covered over the earths surface between the transmitter and the point where a radio signal skywave returns to earth is referred to as the
Skip distance
On a lamberts projection, straight lines approximate
Great circles
On a polar stereographic projection, great circles are approximately straight lines
Near the poles
In the northern hemisphere, the great circle track bearing decreases when flying
West
On a lamberts projection, the distance scale is expanded
Outside the standard parallels
The function of the loop antenna of the ADF is
To locate the aural null
The surface considered to provide the most reliable and accurate rad alt readings is
Choppy water
The components of an INS which measure linear acceleration are
Accelerometers
If an aircraft heading south over continental Aus suddenly decelerates, the compass reading will initially
Remain steady
HF radio waves primarily propagate by
Single and multi-hop sky waves
The frequency of a radio signal is defined as
The number of wavelengths passing a given point in one second
A horizontally polarised radio antenna transmits a signal which is
Horizontal in its electrical element and vertical in its magnetic element
The MF band predominantly uses
Ground
FYI magnetic variation is applied at the station for VOR bearings and at the aircraft for NDB bearings
Sure gal
On a Mercator projection a straight line represents
A rhumb line
On a polar stereographic projection, rhumb lines/great circles are
Curved concave to the pole & straight lines at the pole becoming concave to the pole at low latitude
