A canny pilot once advised me to “Get high, stay
high”, and whilst that provides a good chance of
making it home, it can result in a long, slow
flight
XCSoar records your average climb rate at
different heights and can display this in a
“thermal profile” indicator at the top left of the
screen, which you can use to judge the optimal
height band to fly in (7.7)
◦ Config/Config/System/Gauges/FLARM, Other/Thermal
band=On (13.14)
The Y axis indicates height, the X axis indicates
climb rate and the black arrow indicates your
current height within the band
Warning: lift strength changes over time; since
y
ou are likely to spend most of the flight up
high, the lift strength information recorded for
low altitude may no longer be current!
