This MacNews Category Review looks at flight planning software for the Mac. Products covered include FlightMath and Mac Flight Planner.
FlightMath (http://www.trivectus.com/index.php?content=Products/Products/FM/index.php) is designed to ease the mathematical calculations associated with planning a flight. For instance, instead of using a mechanical slide rule to compute course corrections in wind, you simply drag the hands around a compass rose, with a hand each for wind direction and true course.
Mac Flight Planner
Mac Flight Planner (http://homepage.mac.com/scolebrook/MacFlightPlanner/) is described as “the only flight planning software designed for use by real pilots for real flying on Mac OS X.” It’s not meant to replace your existing flight planning system, but to supplement it.
