Q

A is N55° E/W 000°, B is N54° E 010°

If the average true course of the great circle is 100°T, the true course of the rhumb line at point A is..

A

100°, málið er að average true course er bara þarna á milli þar sem great circle trackið er bara nákvæmlega það sama og true trackið (mitt á milli er eini staðurinn þar sem þetta er það sama). Annars er þetta alltaf minna öðru megin og meira hinu megin.

Q

Hver er formúlan fyrir departure (vill líka fá einingarnar)

A

Departure (nm) = Ch.Long(min) ×cos.lat

Til að fá ch.long milli 10°E og 00° þá segir þú 10 * 60 = 60.
