  • navigation - What is a rhumb line? - Aviation Stack Exchange
    a rhumb line, rhumb, ( rʌm ) or loxodrome is an arc crossing all meridians of longitude at the same angle, that is, a path with constant bearing as measured relative to true or magnetic north From: Wikipedia If continued, all rhumb lines except the ones following a track of 90 or 270 degrees end up in either the North or South Pole If continued, all great circle lines end up back where they
  • How does QDM from a VDF station account for great circle vs rhumb line . . .
    You're right on the principle, if you want to fly at constant heading, you need to get the bearing computed for a rhumb line (loxodrome) assumption Source The VDF measures the bearing according to the direction of arrival of the wave from the aircraft transmitter via the shortest path, hence this QDR angle, converted into a QDM, is the one at the end of a great circle, not at the aircraft
  • Calculate position of point along Rhumb line given the distance from . . .
    The Rhumb line between two points using the Mercator projection looks like this: My goal would be to find the mathematical formula to identify the coordinates of a generic point along the Rhumb line by knowing the distance from the point of origin (or of destination)
  • Is it possible to fly to any destination on a rhumb line track?
    If we follow a constant rhumb line track, it would eventually lead to the pole (depending on your hemisphere) , so then it may not be possible to fly between any two points on a rhumb line track?
  • When flying a great circle route, does the pilot have to continuously . . .
    Extending a rhumb line in one direction ends to the corresponding pole, such curve is actually a spiral between the two poles Navy and Mercator charts A great circle (actually a geodesic) is the shortest path between two points, but it is difficult to navigate
  • How best to divide a Rhumb line into segments of equal real length?
    How might I subdivide that Rhumb line segment into multiple segments, each with equal real length on the unit sphere? Subdividing for equal length in Mercator space is obviously very easy, but I struggle to visualise how I'd find the midpoint or third-points by actual distance on the surface of the sphere
  • How to use a Rhumb Line? - Mathematics Stack Exchange
    I am new to working with coordinate data and figured out the equation I am looking for is the Rhumb Line I went to go research it and found a lot of equations and I still have no idea where to sta
  • geometry - On a sphere, does a rhumb line always exist between two . . .
    The above computation shows that it does, at least provided neither of the points is a pole, and generically that there are infinitely many rhumb lines connecting two points; you can check readily that you can always find a rhumb line passing through a pole and a given second point, and the only headings that take you between the two are
  • navigation - How should I interpret the difference in flight direction . . .
    How should I interpret the difference in flight direction (azimuth) for great circle and rhumb line? Ask Question Asked 10 years, 9 months ago Modified 9 years, 7 months ago
  • What rhumb lines of a torus are periodic $C^1$ curves?
    The rhumb lines are the one crossing the meridian circles with a constant angle The meridian circles are the one lying in planes containing the axis of revolution of the torus
