Navigation using the One in Sixty Rule Use of One in Sixty Rule One in a sixty rule is useful for pilots to quickly calculate alteration of heading One in sixty rule statement states that one unit off-track in 60 units along track mean a track error of 1 degree In other words, if you are 1 NM off-track after a flight of 60 NM, the track error would be 1 degree. Logic behind One in Sixty Rule Logic of One in Sixty Rule is based on an approximation with…

Triangle of Velocities or Vector Triangle or Wind Triangle Plotting Plotting is the means of keeping track of aircraft position at all times during a flight Pilots are legally mandated to be aware of their position at all times during a flight Track and Air Plot are the two means of keeping track of aircraft position Track Plot Track plot is maintained by connecting the ground positions of aircraft Track plot is the simplest means of keeping track of an aircraft position Planned track (PT)or Track Required (TR)is intended flight…

Earth Magnetism and Magnetic Compass Earth Magnetic Field Earth behaves as a large magnet with a Magnetic North and South Magnetic North is the direction indicated by the blue end of a freely suspended magnet Earth’s magnetic field is not exactly aligned to its polar axis since the Magnetic North is not co located with True north Magnetic north is approximately 400 NM away from True north and moves at at a slow rate of 22 NM per year Magnetic North and South poles are not diametrically opposite to each…
