If an Airspeed Sensor is connected to the system, the pilot can make use of expanded ECU functions:
In the "Run" menu the currently measured airspeed ("Airspeed") and the nominal speed ("SetSpeed") can be
displayed.
In the Min/Max menu the measured maximum ("MaxAirSpd") and calculated average ("AvgAirSpd")
airspeeds can be displayed on the screen.
In the "Limits" menu the operator can set limit values and/or adjust the characteristics of the speed governing
system.
List of parameters in the "Limits" menu which are assigned to the Airspeed Sensor:

Explanation
Maximum permitted airspeed of the model in km/hr. If this airspeed is exceeded, the
ECU automatically throttles back the turbine to a point where the airspeed is just
below the set limit value. This is a safety option, and is always active, regardless of
the position of the 3-position switch.
The value set here corresponds to the model's airspeed in km/hr at the full-throttle
setting of the throttle stick in "Speed-Control" mode.
The value set here corresponds to the model's airspeed in km/hr at the idle setting of
the throttle stick in "Speed-Control" mode.
Governor speed: defines the response characteristics of the speed governing circuit
(similar to the gain setting on a gyro system)
Default value: 18
Governor coefficient (proportional value)
Default value: 500 (should not normally be changed)
Governor coefficient (differential value)
Default value: 50 (should not normally be changed)
This option defines the behaviour of the ECU (when the Airspeed Sensor is
connected) when the 3-position switch is moved to the "OFF" position (= 0, back) and
the model is in the air (i.e. airspeed > 40 km/hr).
The possible options are:
"Hold-Speed" = maintain current momentary airspeed
"DISABLED/NONE" = no function ("Thrust-Control" remains active)
"Turbine OFF" = shut down turbine immediately, as previously
"LrnSpeed Lo/Hi" = Learn speeds
"Lrn Speed Lo = Learn slow airspeed
"Lrn Speed Hi = Learn high airspeed.
This option defines the behaviour of the ECU (when the Airspeed Sensor is
connected) when the 3-position switch is moved to the "AutoOff" position (= 2,
forward) and the model is in the air (i.e. airspeed > 40 km/hr).
The possible options are:
"Hold-Speed" = maintain current momentary airspeed
"DISABLED/NONE" = no function ("Thrust-Control" remains active)
"LIN-Speed Ctrl" = Regulate speed in linear mode
"3-StepSpdCtrl" = Regulate speed in 3 increments.
