Chart Tracking Mode

When GPS position information is available, the Chart Tracking mode adjusts the

enroute chart according to your aircraft position. Clicking the Chart Track button
cycles between four settings:

Optimum mode shows the maximum amount of chart area ahead of

the aircraft symbol, moving the chart beneath it along the planned
route.

Centered mode centers your aircraft in the screen and moves the

chart beneath it.

Visible mode moves your aircraft icon across the chart view. This

mode requires the least CPU performance because the chart moves
only when the aircraft flies off the edge.

Route mode zooms out to show the full route.

When you click one of these buttons, the status bar indicates which tracking mode
you have switched to.

Chart Orientation

When GPS position information is available, the chart can be rotated, the way some

people like to hold paper charts. Clicking the Chart Orientation button cycles
between three options:

North Up keeps the top of the chart at the top of the screen and true

north, like a standard paper chart.
