Instant glide ratio : is noted « GRI » for « Glide Ratio Instant ». This item shows your current glide
ratio. GRI = Ground speed / Vario.
Smoothering the glide ratio value is possible through the advanced parameters from the SYS PC
Tool (menu « Option / Setup / Instrument / Advanced parameters ».
Heading : is your current instrument’s magnetic orientation. Note that this indicator is corrected by the
magnetic declination, which depends on your current position. As a consequence, this item displays the
true heading instead of magnetic heading.
Course : is your current course. Without wind, the course equals the heading.
Drift angle : is the difference between your course and your heading. Drift angle = Course – Heading.
Temperature : gives the internal temperature of the instrument.
Back to previous thermal : the SYS’Evolution always keep track of the previous thermal. Fly
in the direction the arrow is pointing to go back to the previous thermal.
