4.2 TSK NAVIGATION MENU
This menu has two important functions.
1.
Navigation
- It allows in-flight navigation using only the turnpoints of the task. This prevents
manually cycling through the entire TP database when on a task. Please note after the task has started,
i.e. you have entered the start point cylinder or sector,
there is an automatic change over to the next
Turnpoint of the task after rounding the current TP.
2.
Task declaration for the logger
- after take off
the selected task is written into the logger
and will remain there till landing.
The selected task is automatically declared after take off.
Only
one TSK
can be memorized in this menu. To input a task in to this menu use one of two methods:
Press the ‘Enter’ key and the ‘EDIT TASK’ option is displayed, Press ‘Enter’ again and you can cycle
through the TP’s of the task, changing the TP’s as required. That is, press ‘Enter’ when the old TP is
displayed and you then have the SELECT, INSERT,DELETE TPOINT options.
OR
Press the ‘Enter’ key and the ‘EDIT TASK’ option is displayed, press the ‘Down’ arrow key and the
‘COPY TASK’ option is displayed. Press ‘Enter’ again and the 100 (0-99) task database stored in the
Colibri is accessed. Use the ‘Up/Down’ keys to copy the task you desire.
NOTE: - Editing task in this menu will not change the task as stored in the task library (0-99).
How to fly the TSK
Prepare the task using copy or edit method as described above. The task stored into the IGC logger
must have following structure:
-TAKE OFF
-START POINT
-TURNPOINTS
-FINISH POINT
-LANDING
TAKE OFF and LANDING are classed as turnpoints as well. Which means they should be entered using
the TP library. The stored tasks in the TP library don’t have take off and landing points. So after having
copied a task from the library, you will find the TAKE OFF point = START point and the FINISH point =
LANDING point. Using EDIT procedure it is possible to change these two points so the task matches the
FAI structure shown above. TASK declaration is easier to do using the LXFAI program and uploading the
task via the ‘WRITE FLIGHT INFO’ menu option.
IN FLIGHT
Immediately after take off the TASK navigation screen will change automatically from the TAKE OFF
point to the START POINT (TSK:STA). That is the navigation screen will automatically display data to
guide you to the start point of the task.
Once you reach the START point (photosector, cylinder …) an acoustic alarm is activated and a
manual
change-over
to the first turning point is necessary (use the ‘Down’ arrow key). Often you fly through the
start point sector many times before actually commencing your task (i.e. in competitions). You must
manually select the first Turnpoint of the task to tell the Colibri you have actually started the task.
