4.2.9 TOTAL ENERGY COMPENSATION (WITH OPTIONAL PITOT TUBE)

To use this function, it is necessary to have the optional Pitot tube installed.

Generally, a variometer works as follows: it feels the atmospheric pressure change rate considering it as an
altitude change, but, if during the flight the pilot slows the glider (and even more so if done quickly), there is a
real change of pressure, so a vario ‘without compensation’, records it as a climb, but this variation is caused by
a change of speed (kinetic energy) and not due to a true thermal.

With the Total Energy Compensation function, the part of the climb due to the change in velocity is ignored,
allowing you to identify the “real” thermals.

To properly set the TOTAL ENERGY compensation values, you need the following parameters:
o
"Total Energy Compensation Mode" (VARIOMETER SETUP \ n. 13 TECM) : OFF = T.E.C. off (default), ON = T.E.C.
is calculated during glide only, FUL= T.E.C. is calculated both during glide and in thermals.
o
“Total Energy Compensation” (VARIOMETER SETUP \ n. 14 TEC), to set this percentage correctly, you should
fly in calm air conditions and slow down as if you were entering a thermal. If the vario shows a change in lift,
you have to increase the total energy compensation value, until the change in velocity is no longer recorded as
lift; a typical value for hang gliders is 65.
o
"Total Energy Compensation Average" (VARIOMETER SETUP \ n. 15 TECA): it is the average applied to the total
energy component, the range goes form 1 (fast) to 99 (slow); default 80.
