component in the direction you are tracking calculated from the
last valid vector wind (speed and direction). That is, the wind
component you should be seeing in the direction you are going -
this should be close to the wind component shown by the first
pointer - unless the wind has changed.
In flight, this gives you immediate warning that the wind has
changed as the first and last mentioned pointers will split. When
tracking for the next turnpoint the three pointers should all be
aligned if the wind hasn't changed.
In CLIMB mode:
the wind component pointers disappear, to be replaced by 3
vertical bars representing Flight average, thermal average and 20
second running average rates of climb with the average rate of
climb for the whole thermal under the bars. Superimposed on the
20 second running average is a marker representing the current
vario reading. It is in reverse video when the vario is less than
the running average.
To the right is a triangular pointer representing the current
Macready setting.
It's easy to see if the thermal is any good, getting stronger or
weaker at a glance and the number and Macready pointer
provide scale as well as simple comparison of rates of climb to
the Macready setting.
If the thermal is at least as good as the flight average so far and
getting better, the tops of the bars will slope up to the right. This
is obviously desirable. If the right bar goes down below the
middle bar the thermal is getting weaker as the current running
average rate of climb is below the total rate of climb in the
thermal so far. It is time to consider leaving. If neither the center
bar nor the right bar get above the left (flight average) bar you
should have a good reason for staying in the thermal - like you
suspect it may be the last one or you need the altitude to cross a
dead area.
When on the final leg the glider symbol is enclosed in a square. This is important on POST and
similar tasks as once you fly through a finish sector for the last place currently selected on the
PLAN page the B2000 is FINISHED as far as statistics are concerned. When you see the square
make sure you REALLY want to finish at the next place. If you do not want to finish just select any
other place in the next slot on the PLAN page. You can change it later, even after rounding the now
next-to-last turnpoint.
Alternatively set the B2000 to use MANUAL turnpoint rounding to avoid this problem(TASK
TYPE page).
Graphics symbols around the glider :-
These are used on both the FLT-TO page and the MAP page.
