Glide Ratio = ( L/D Ratio ); Mounting The Instrument; Guarantee And Liability - Brauniger IQ-CLASSIC Operating Instructions Manual

Barogram, speedogram and variogram can all be shown on-screen, each with zoom function.
In addition, the relevant data can be read from the diagram using a cursor and differential
data can also be displayed using a second cursor. Annual statistics are available as well as a
special interactive diagram for the assessment of polars.

Glide ratio = ( L/D ratio )

According to definition, the current glide ratio is the distance covered divided by the altitude
lost while doing so. Or even without major errors: speed divided by descent. If an instrument
in the IQ series with a speed sensor is being used, the current glide ratio through the air is
shown continuously in the upper beam row
as the result of the above division operation.
Connecting a GPS receiver to the vario will
provide a display of the wind-corrected glide
ratio above ground. Nevertheless, these
displays are not particularly meaningful
since the results are always linked to a
descent of the instrument and are therefore
subject to continuous change like the vario.
In setting mode no. 9, it is also possible (by choosing no. 3 instead
of the digital vario) to depict the glide ration in digital form between 0.1
and 19.9.
When the pilot has activated the "Goto" function in the GPS receiver connected, there is an
automatic switch away from the current glide ratio. Instead, the display indicates the glide
ratio required to reach the destination selected with "Goto". The glide ratio required is
calculated from the distance/difference in altitude. It is immediately clear that this result is
independent of wind, vario or flying speed and therefore it is not possible to make any
"leaps".
This GZ is exceptionally interesting to paraglider pilots flying without a speed sensor. If
the required glide ratio continually increases during the approach to a target, it will be
impossible to reach the latter without any additional thermals; if the required glide ratio
continually decreases, it will be possible to fly faster so as not to arrive at the target at too
high an altitude.

Mounting the instrument

There are different ways of attaching the instruments for hang-glider as well as paraglider
pilots. Please ask your dealer or the manufacturer.

Guarantee and liability

Our instruments carry a 24-month guarantee. However, physical damage such as a broken
casing or glass breakage as well as damage resulting from water landings are excluded from
this guarantee. Bräuniger can accept no liability for faults arising from any abuse or
unapproved use of your instruments.
