Operation
Pressing both the
and
buttons briefly at the same time launches the
chronometer (brief display of the message
). This can
be done from any screen, and whether the instrument is turned on or off.
Pressing briefly the
button freezes the screen, which allows to read an
intermediate time (the instrument keeps counting the time while the
display is frozen). The chronometer returns to normal mode at the end of
10 seconds or by pushing on
twice.
Remark: At a later stage it is possible to view all the times recorded by
the chronometer via the memory display, since every time you start a
chronometer, you carry out a manual recording of all the measurements.
Density Altitude
Display
The density altitude is the current altitude should the air be in a
standard air environment. The density altitude is corrected using the
real air density; it therefore constitutes an essential factor in the
computation of the performance of an engine or the lift of an aircraft.
The density altitude is displayed as followed:
upper block
: Wind speed
large block
:
indication
middle block
: default mode (here temperature)
lower block
: density altitude
+ compass heading
Operation
You have the option of changing the measuring mode displayed on the
middle block
, which shows the default basic mode of the standard screen.
To change the display, select this
block
(it flashes), then press the
button briefly: you can display either the ambient temperature or the
relative humidity.
