For this question you need a plotter to find the true track and measure the distance between FÜRSTENZELL aerodrome (EDMF) and Metten helipad.

Calculate Magnetic Track:

• Firstly, find the exact position of EDMF aerodrome and Metten helipad symbols on your Jeppesen ED-4 chart, using the coordinates given and draw a line with your pencil to connect these two points.
• Center your plotter at EDMF aerodrome symbol, since the question asks for the track from EDMF aerodrome.
• Align the upper section of your plotter with the line which connects the two points.
• Rotate the plotter’s disc, until its arrows are parallel with the chart’s meridians and indicate the True North.
• The aligned with the route EDMF to Metten helipad plotter’s arrow indicates the True Track 322°.
• The two points are close to the 3°E isogonal.
• Thus, following the rhyme "Variation East, Magnetic least", the Magnetic Track is: 322°T - 3°E = 319°M approximately.

Calculate Distance:

• It is known that the ED-4 chart's scale is 1:500 000, as depicted in the frontal blue page of your GSPRM's ED-4 chart.
• Using the appropriate scale of your plotter (SECTIONAL 1:500 000/NAUTICAL MILES), you will find that the distance between EDMF and Metten helipad is 26 NM.
