When the Aus LL GPWT option is selected, thumbnails of all available GPWT charts are displayed in a grid view, grouped by validity period. Tap on a thumbnail to view a chart.

GPWTs outline wind and temperature profiles for a three-hour period, from the Surface to 14,000 feet. Your flight plan route is overlaid as a red line on the charts, so you can visualise which grids your planned track passes through.

Each grid square contains three columns of data:

  • Left column: Wind direction in two figures, rounded to the nearest 10° (e.g. 270° is displayed as 27, 090° is displayed as 09, and so forth)
  • Centre column: Wind velocity in three figures
  • Right column: Temperature (red for positive temps, blue for negative)

And six rows, each one representing an altitude AMSL:

  • 14,000 ft
  • 10,000 ft
  • 7,000 ft
  • 5,000 ft
  • 2,000 ft
  • 1,000 ft
