THERMAL SNIFFER
To utilize the thermal sniffer function, you must have an air speed probe connected. The
optional air speed probe should be plugged in to the right hand socket on the bottom of
the vario.
If this parameter (ADVANCED SETUP \ n. 8 POLA) is set to “OFF”, all display information
relating to McCready, McCready Equivalent, Thermal Sniffer is not displayed on the
instrument, creating a cleaner display for users not needing this functionality.
The thermal sniffer is an innovative function that helps you to detect a thermal early.
It alerts you with a sound and the popup message “THERMAL” when you are in a
thermal but your vario is still indicating sink because your sink rate is higher than the
speed of the rising air.
This function uses two parameters, the thermal strength and the time over which the
thermal must occur.
To set the thermal detection parameters, go to (ADVANCED SETUP \ n. 2 THEV) and
(ADVANCED SETUP \ n. 3 THET) to adjust the vertical speed (vario) and for how many
consecutive seconds this vertical speed has to be detected.
To use this function you need to set up the polar of your glider.
