After take-off from EDHL (Lubeck) on Route 1 (yellow), you head directly to NOVEMBER. How can you verify reaching turning point NOVEMBER by using radio aids?
Remark: Radials and bearings are approximate.
-
A
Tune in the Hamburg (HAM) VORTAC (113.10 MHz), radial 055 together with the corresponding DME reading.
-
B
Identify the nearest NDB and check its bearing to determine the turning point.
-
C
Tune into the Lübeck VOR/DME (LBE) and verify your position based on DME distance alone.
-
D
Rely on ATC for confirmation of reaching the turning point without using navigational aids.
Refer to figure.
A turning point can be verified using a VOR/DME navigational aid, through a radial and a DME distance, if tuning in its frequency.
Radial is a magnetic bearing extending from a VOR (QDR). The circle around the VORs works as a protractor, which is aligned with the Magnetic north. Thus, any straight line emanating from the centre of the VOR symbol represents a magnetic bearing or radial (or QDR).
DME distance is a slant distance from a DME.
Hamburg (HAM) VORTAC can be used to verify turning point NOVEMBER, if tuning on its frequency, 113.10 MHz.
Using the circle-protractor, draw a straight line from HAM VORTAC symbol, to find the radial which passes through turning point NOVEMBER. The radial from HAM VORTAC (113.10 MHz), passing through turning point NOVEMBER is R055.
The R055 along with the corresponding DME reading, will give the exact position of NOVEMBER point.
