5.3.2.3
TAS method
You can select three methods how true airspeed is calculated.
Altitude only
method is
using standard temperature profile with altitude and shall be used only in case OAT probe is
not mounted or not working properly,
Altitude and OAT
is method which takes into
account density change due to altitude change and temperature change.
Altitude, OAT
and Compressibility
is method which takes into account also compressibility of the air and
shall be used for faster aircrafts.
5.3.3
Vertical speed
Vario bar filter value defines response of the vertical speed indication. Higher value of filter
will cause more slow and more filtered response of vertical speed indication.
TE compensation is used mainly for gliders in order to show total energy change rather than
vertical speed. Set to 100%, if you want to have compensated vertical speed indication or
leave on 0 to have non-compensated vertical speed.
5.3.4
Temperature
A temperature offset can be defined here. Temperature offset is same for the whole
temperature range. Temperature offset should be set on the ground. If temperature
indication is the air is not ok, you should consider relocating OAT probe.
5.3.5
Battery
Airdata indicator can also shows battery information in case it is running on batteries. Select
battery type from the list or enter values manually.
