9 QUICKSTART
• The estimated elapsed time to complete the task with different MacCready settings can be
explored by pressing Calc . Adjusting the ’range’ setting shifts the targets within the AAT
sectors to increase or decrease the task distance.
• Open Analysis and select the ‘Task’ page to preview the task on a map.
In-flight
• When the pilot is ready to start the task, press Arm Advance . The current waypoint will
then advance automatically once, as the pilot flies through the start sector. After this occurs,
the advance trigger is disarmed.
• In order to re-start, the pilot needs to press Arm Advance again prior to flying through
the start sector again.
• 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.
• During flight, the estimated elapsed time to complete the task with different MacCready
settings can be explored in Task calculator . Adjusting the ’range’ setting shifts the targets
within the AAT sectors to increase or decrease the task distance. Typically, the pilot should
set the range such that the estimated elapsed time is greater than the assigned task time.
If conditions are improving, such that the pilot wishes to fly deeper within an AAT sector,
the range can be increased. Likewise, if conditions are deteriorating, the range can be
decreased to a value at which the estimated elapsed task time is above the assigned task
time. This allows the pilot to effectively increase or decrease the task distance.
The figure below shows the course around the targets at range set to −100%.
