5. Press and release the H MODE button. The arrow will be placed at the LAS (low airspeed)
setting field.
 Set the lower airspeed for the corresponding TL setting.
6. Press and release the H MODE button The arrow will be placed at the HAS (high airspeed)
setting field.
 Set the airspeed corresponding to the low trim speed (TH) setting.
The V-TRIM SPEED/DIR is complete and the encoder can now be used to select another menu screen.
Trim Setting Example:
The pilot desires a fast trim movement an airspeed of 100 kts for since the trim is less effective at slower
airspeeds and a slower trim movement at greater than 150 kts since the trim movement is more sensitive
at higher airspeeds.
In this example the pilot enters:
 A trim movement (TL) of 18 (very fast trim response)
 The low air speed (LAS) setting 100 kts
 A trim movement high (TH) of 6 (very slow trim response)
 The high air speed (HAS) setting of 150 kts
NOTE: Between an airspeeds setpoints of 100 and 150 kts (LAS and HAS) the trim movement speed is
linearly interpolated between the TL and the TH settings. In this case, an airspeed halfway
between 100 and 150 kts (or 125 kts) would result in the speed of trim movement half way
between the TL and TH setting, in this case 12.
When adjusting the trim values it will be noted that the firmware has been designed to prevent any
“crossover” in the settings. That is, the HAS can never be lower than the LAS, and vice versa. The
same is true for the TL and TH settings.
