and finish zone. Start out the top will enable detection of start, when leaving start sector
from the top of it.
The Navigate to nearest point option is very useful and actually a must if a
finish cylinder is used with a significantly large radius. Enabling this option will
calculate the final glide to the edge of the cylinder rather than to the centre of
the cylinder.
There are also several options in this menu which will help competition pilots to have a less
stressful start.
6.7.5.1 Gate Time
Gate time is the time when the start gate is going to open. If this value is entered the
instrument will not give you any message about starting a task before the gate time is
reached. A notification will be given when the gate is opened.
6.7.5.2 Below Altitude Start Procedure
On some competitions there is a rule that a pilot must be below a defined altitude for a
certain amount of time. Enter Below alt. and Below time to use this option. An
indication will be given on the final glide symbol. Character “B” will be displayed before the
MacCready value which indicates that the final glide is in below altitude mode.
The lower number shows the difference to the set altitude. Negative values mean altitudes
below set altitude. The upper yellow number indicates the number of seconds left to be
below the set altitude. Chevrons indicate meters below or above required altitude. Each
line represents 10 m. A message “You were XX seconds below YYYYm!” is displayed once
you fulfil the conditions.
6.7.5.3 Maximum Start Speed and/or Maximum Start Altitude
A lot of competitions are limiting the start altitude and/or start ground speed. The system
helps pilots to cross the start line at the correct altitude with correct ground speed. Enter
Start alt. and/or Start gsp. to use this option. An indication will be shown on the final
glide symbol. Character “A” will be displayed before the MacCready value if a start altitude
was entered and/or character “G” will be displayed if a start speed was specified.
