The Air speed indicator
The airspeed indicator (ASI) can indicate airspeed in mph (miles per hour), knots (nautical
miles per hour) or km/h (kilometers per hour). This is selected in the mode and units setup
menu. The Ultra ASI provides a range of 16mph to over 250mph.
You can choose from four different airspeed indicators.
The traditional analog airspeed indicator. You can select a scale suitable for
your application. Choose from a grading of 80, 100, 150, 200, 300, 400 units of
measure.
Tape based airspeed indicator. This is normally used if an artificial horizon is
displayed. You can select the steps between the tape gradients to suit your
airspeed range.
Tape based airspeed indicator with a left bias.
For busy panels a numeric airspeed indicator can be selected to save space.
You can enable a “ASI” label and a airspeed units readout. Further to this you
can enable a true airspeed readout and corresponding label. The true airspeed
readout is based only on the altitude, assuming a standard gradient. This means
that the true airspeed readout will work even if you do not have an ambient
temperature sensor installed.
The ASI may have alarms enabled. If the alarm is enabled, the settings for Vs (stall speed) and
Vne (never exceed speed) will be used as limits. When the alarm is active, the ASI readout will
flash.
Note: If you have automatic flight detect enabled, the ASI readout will flash after you have landed
for a short while until the flight has ended (logbook entry has been made).
You setup the V speeds in the Basic operations setup menu.
