NOTE: The logger capacity figure displayed on the above screen doesn’t indicate the remaining portion
of unused memory ! It displays the total memory available for flight recording, which depends upon the
logging time interval and additional data options selected for recording. As old data is automatically
overwritten by new data (ie. the current flight) you don’t need to clear the memory prior to flight.
Hence, after a flight you will find the logger memory number displayed has remained unchanged.
However, changing the recording interval or selecting additional data recording options (see section
5.1.d of the manual) will change the amount of memory available and change the value displayed.
4.0 NAVIGATION MENU
This menu allows in-flight navigation to the selected turnpoint and also editing of the turnpoint data. A
typical navigation screen looks like this.123t CUND
126b235km
123°
°°
°is track, 126°
°°
°bearing, 235km is the distance to the TP and CUND is the first four letters of the
turnpoint (designator). The Colibri counts down the distance to a TP in 1km increments, except when the
glider enters the radius around the TP that is set in the Logger Setup menu (see 5.1). Then the Colibri
displays the distance to the TP in 100 metre increments. This is very useful for competition as you
approach the turnpoint and often loose sight of it under the nose of the aircraft.
Once you have rounded a turnpoint the next turnpoint can be selected by simply using the vertical
arrows. After a short press of the UP or DOWN arrow a new turnpoint, which follows the old one
alphabetically, will be displayed. For approximately 1 second the turnpoint designation is shown in 8-
character form to confirm your selection. The internal database has a capacity for up to 600 turnpoints.
To make your TP selection quicker there are special algorithms which allow you to jump over TP’s. After
the ‘UP’ or ‘DOWN’ arrow is pressed and held down, the Colibri jumps through the TP database in larger
increments. Once the required TP is reached release the key and that TP will automatically be entered
for navigation purposes and the display will update bearing, track, TP name and distance to go.
Pressing the ESCAPE key in this screen will cause the four-letter TP designator to be replaced by a
display of the aircraft’s ground speed. Press the ESCAPE button again and the wind calculation
procedure is started. Wind speed and direction will be displayed as follows.
0980
25kph
The method of wind calculation is based on ground speed changes caused by wind effects during
circling (thermalling). To calculate the wind reading the Colibri requires two circles of the aircraft
(constant speed and no pilot induced change of position).
Pressing ENTER from any of the pages in the NAVIGATION menu will select the Turnpoint menu.
Which allows editing of turnpoint data and also task editing. The following screen will appear:

After using the ‘DOWN’ arrow, four sub menus will appear. Using the UP arrow reverses the order of
