IGC flight log file analysis for gliders / sailplanes, hang-gliders and paragliders. FEATURES • View and analyse IGC flight log files from gliders / sailplanes, hang-gliders and paragliders. • Native application for macOS. • Privacy. Your IGC files remain on your Mac and are never uploaded to the internet. • Optimised for both Retina and non-Retina displays. • Plots the geographic trace of the flight onto a detailed satellite imagery map. • Trace can be coloured with altitude, climb rate, engine usage (from ENL & MOP), glide angle/ratio, ground speed and position fix accuracy. • Global high resolution satellite imagery coverage (extremely useful for determining which ground features were generating lift or sink). • Map can be scaled and panned with Multi-Touch gestures (E.g. pinch to zoom). • Plots an altitude graph of the flight. • Moving the cursor over the altitude graph displays the flight state at the corresponding point in time. • Clicking on the altitude graph places a reference marker from which time/altitude deltas and averages are calculated and displayed. • Flight information display including pilots name, aircraft ID, aircraft type, take-off time, landing time and flight duration. • Allows each flight in a log file containing multiple flights to be analysed separately. • Configurable between metric (m, km/h) and classical (ft, knots) units systems. LIMITATIONS • GammaFV is not certified for, nor intended for use in, flight safety related activities. Such activities include, but are not limited to, pilot hours tracking and airframe flight hours tracking.
