Chapter 3 : G91 Operation 

17 

3.5

 

Actuator Options 

The G91 has a number of actuator options to maximize flexibility and simplicity of 
operation.  

The programmed 

Joystick Switch Threshold

 will determine the joystick deflection 

required to operate any Actuator functions. 

The programmable option 

Both Leg Rests Enable

 

allows extra flexibility by 

simultaneous operation of DX- CLAMB channels 3 and 4, refer Section 5.3. 

 

3.5.1

 

Conventional Actuators 

This is the default configuration for G91 actuator control.
