2. In order to re-start, the pilot needs to press the ‘Arm Ad-
vance’ button again prior to flying through the start sector
again.
3. After the task is started, the ‘task status’ dialog 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. Otherwise it will
display ‘INVALID’.
4. During flight, the estimated elapsed time to complete the
task with different MacCready settings can be explored from
the ‘task calc’ dialog. 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%.
