Choosing the Flight Mode
1) Press the Navigation Pad 56 to highlight GYRO, then press the ENTER key to display the GYRO menu. The cursor will
default to GYRO1>100%.
2) Press the F-MODE key to choose the F-MODE number you would like
to program the Gyro function for. Choose from N, 1, 2, 3, or 4. The
F-MODE (N) display will change, indicating which Flight Mode you are
programming the Gyro function for.
Changing the Gyro Percentage Values
The Gyro percentage values determine both the amount of gain and the gyro operating mode - either Heading Hold mode or Rate
mode. In general, positive values will result in your gyro operating in Heading Hold mode and negative values will result in your
gyro operating in Rate mode. The amount of gain is determined by the percentage value.
IMPORTANT Whether you use positive or negative Gyro percentage values to program your gyro in either Heading Hold
mode or Rate mode will be determined by the NOR/REV settings of the gyro channel in the Surface menu. For example, if the
gyro channel is set to NOR (Normal) in the Surface menu, positive Gyro percentage values may result in your gyro operating
in Heading Hold mode, but if the gyro channel is set to REV (Reverse) in the Surface menu, positive Gyro percentage values
may result in your gyro operating in Rate mode. You will need to test your gyro to ensure that it's operating in the desired
mode based on the percentage values, then adjust the percentage values accordingly to achieve the desired amount of gain.
1) Press the Navigation Pad 56 to highlight GYRO1>100%, then press
the YES/+ or NO/- keys to change the Gyro 1 percentage value.
When the Gyro 1 percentage value is set to 0%, the gyro will be in
'pass-through' mode (e.g., OFF) for that selected Gyro function only.
2) Press the Navigation Pad 6 to move the cursor to GYRO2>-100%,
then press the YES/+ or NO/- keys to change the Gyro 2 percentage
value.
3) Press the Navigation Pad 6 to move the cursor to GYRO3>-100%,
then press the YES/+ or NO/- keys to change the Gyro 3 percentage
value.
GYRO1, GYRO2, and GYRO3 setting range is -150% to 150%. The GYRO1 default setting is 100%. The GYRO2 and GYRO3
default settings are -100%. Decreasing the GYRO percentage values decreases gyro gain and increasing the GYRO percentage
values increases gyro gain. See the IMPORTANT note above regarding the use of positive and negative Gyro percentage
values and how they may change your gyro operating mode.
If you prefer to use the same Gyro function settings across all Flight Modes, instead of programming separate Gyro function
settings for each Flight Mode, you can control up to two separate Gyro function settings via a three-position switch. To do
this, plug your gyro into the AUX2 channel and adjust the AUX2 channel High and Low End Point Adjustments in the Surface
menu to set the desired Gyro percentage values. Positive or negative values will determine your gyro operating mode - either
Heading Hold mode or Rate mode, as described above. In the default configuration, Switch Position 1 is AUX2L and Switch
Position 3 is AUX2H. For example, with the switch in Switch Position 1, you might have 100% End Point Adjustment for maximum
gain in Heading Hold mode and with the switch in Switch Position 3, you might have 75% End Point Adjustment for decreased gain
in Heading Hold mode. When the switch is in Switch Position 2 (centered), the gyro will be will be in 'pass-through' mode (e.g., OFF).
