9 QUICKSTART
9.2 FAI Task
In this scenario, the pilot intends to fly a triangle FAI task with a single start sector and automatic
waypoint advance.
Prior to takeoff
Turn on the device.
Open Basic settings and adjust the bugs and ballast as required. Set the maximum
forecast temperature. Close the dialog.
Open Task editor and press New .
The task now contains the home waypoint as start and finish waypoint.
Add new waypoints with Insert on the ‘Waypoints’ page.
Set the start and sector types, and ensure AAT is OFF. In this example, we set alternate
start points to ‘OFF’ and Auto Advance mode to ‘Auto’. Once finished, press close.
The task is now entered. Open Analysis and select the ‘Task’ page to preview the task
on a map.
In-flight
The current waypoint will advance automatically as the pilot flies through the observation
zones.
After the task is started, Status can be opened to verify a valid start was detected. If
the ‘start time’ is given, the start was detected and legal according to the task start rules
specified in the configuration.
At all times the black track arrow will point at the next waypoint. The blue arrow will point at
the direction the glider should track when in cruise.
If Auto Zoom is activated, the map will automatically zoom in as task waypoints are ap-
proached.
At the appropriate times, set the MacCready automatically, manually in Setup MacCready
, or from the variometer.
Change the bugs/ballast settings as required.
Refer to Analysis as required.
Refer to Status as required. This shows the start time, elapsed time on task, estimated
arrival time, average task speed etc.
At any time, the glider can reach home when the altitude difference bar is a green arrow
pointing upwards.
Optionally set MacCready to ‘AUTO’. If the MacCready mode was set to ‘Final Glide’ or
‘Both’, then the system will command the optimal speed to return home; and the MacCready
value will be set to the minimum climb rate at which it is beneficial to continue to climb.
