  • macOS 10.14 (Mojave)
  • macOS 10.13 (High Sierra)
  • Intel 64bit x86 processors

New features:

  • Average glide ratio, glide angle and ground speed can now be displayed by selecting a time range on the altitude graph when in the corresponding trace colouring mode.
  • Fidelity of ground speed colour scales increased.
  • Glide ratio and glide angle trace colouring accuracy improved.

Version 1.9.0 (38)

Compatibility:

  • macOS 10.14 (Mojave)
  • macOS 10.13 (High Sierra)
  • Intel 64bit x86 processors

New features:

  • Map trace can now be coloured with Engine Usage and Position Fix Accuracy data.
  • Altitude graph is now coloured red where an engine was in use.
  • Engine usage is derived from the IGC file's Environmental Noise Level (ENL) and Means of Propulsion (MOP) data.
  • Improved detection of the start of glider flights.

Version 1.8.0 (24)

Compatibility:

  • macOS 10.14 (Mojave)
  • macOS 10.13 (High Sierra)
  • Intel 64bit x86 processors

New features:

  • Map trace can now be coloured with glide angle and glide ratio data.
  • Improved legibility of trace against map background.
  • Improved accuracy of climb rate (vertical speed) and ground speed trace colouring.
  • Improved naming of trace colouring modes.
  • Added distance scale to the map.
  • Added basic macOS "Dark Mode" support.

Version 1.7.0 (10)

Compatibility:

  • macOS 10.13 (High Sierra)
  • macOS 10.12 (Sierra)
  • Intel 64bit x86 processors

New features:

  • Moving the cursor over the altitude graph now displays the corresponding flight state information on the colour scale key.
  • While in a vertical speed display mode, the average vertical speed is now displayed when a time range is selected on the altitude graph.
  • Fidelity of vertical speed colour scales increased.
  • Flight logs can now be exported as CSV files.

Version 1.6.0 (8)

Compatibility:

  • macOS 10.12 (Sierra)
  • Intel 64bit x86 processors

New features:

  • Flight logs from loggers that only record satellite fix data can now be fully viewed and analysed. However if you have a choice, use a logger that also records barometric altitude data, as it will allow GammaFV to determine vertical speed more accurately.
  • Map trace can now be coloured with satellite altitude and satellite vertical speed data.

Version 1.5.0 (6)

Compatibility:

  • macOS 10.12 (Sierra)
  • Mac OS X 10.11 (El Capitan)
  • Intel 64bit x86 processors

New features:

  • Flight logs from hang-gliders and paragliders can now be viewed and analysed. The appropriate analysis mode (glider, hang-glider or paraglider) can be selected when viewing a flight log.
  • Trace rendering now faster, higher fidelity and more robust.
  • Improved extraction of meta data (pilot's name etc.) from log files produced by hang-glider and paraglider loggers.

Version 1.4.0 (5)

Compatibility:

  • Mac OS X 10.11 (El Capitan)
  • Intel 64bit x86 processors

New features:

  • Moving the cursor over the altitude graph displays time, altitude and location details.
  • Clicking on the altitude graph places a reference marker from which time and altitude deltas are calculated and displayed.

Version 1.3.0 (3)

Compatibility:

  • Mac OS X 10.11 (El Capitan)
