Vario Indicator Unit
. . Thermal assistant page
The Thermal assistant page on the digital vario indicator is very similar to the one already
described previously for the main unit. The main difference is the upright orientation of the
screen, the lack of the altitude sliding tape and the presence of the vario arc.
The TA page incorporates four NavBoxes, showing the following parameters:
• T AVG - shows the average vertical speed for the whole thermal, since the device detected
the start of circling, up to the current point in time
• AVG - shows the integrated vertical speed for the time duration set in the Vario/SC setup
menu
• MAX - the maximum variometer value in the last circle ( 6 degree turn). This is the same
value as is represented by white dot on TA page.
• GAIN - shows the accumulated altitude from the start of circling. The GAIN NavBox
shows the difference between current altitude and altitude recorded at the start of cir-
cling, which means this value can also be negative.
In the middle of the screen, we can see the actual Thermal assistant, embodying the Wind
indicator. The Wind indicator works much the same as already noted in Wind indicator.
The Thermal assistant is an indicator, whose main function is to map the strength of the
thermal in the last full circle and give the pilot an idea of his actual position in the thermal, thus
helping him center.
A glider represents the pilot's current position in the thermal. The glider can be either on the
left side (circling to the right), or the right side (circling to the left) of the Wind indicator.
Next we see dots forming a circle, at 8 degree intervals. These dots represent discretized
parts of the thermal. The dots are either red or blue. Red indicates a lifting part of the thermal
and blue a sinking part. The size of the dot indicates the intensity, larger dots representing
greater vertical speeds, in either direction. A single dot (white when dark theme is used and
