Q

Proper switch/selector positions for the gnd and airborne use of the eng and wing anti-ice system in both icing and non-icing conditions?

A

IN icing conditions
“Switch” airplanes - ON GND - wing OFF, eng’s ON
- Airborne - wing ON or OFF as req’d, eng’s ON. Wing anti-ice, if req’d, is selected ON during the after T/O flow.
“Selector” airplanes - ON GND - wing OFF, eng’s ON.
- Airborne - AUTO/AUTO/AUTO accomplished on the after T/O flow.
Note: eng bld air MUST be used for engine anti-ice, APU bld air is insufficient. When running a single eng, only run ONE pack is also using eng anti-ice on the ground.
NOT in Icing Conditions:
“Square Switch” airplanes - all switches OFF.
“Selector Switch” airplanes - on the gnd - wing OFF, eng AUTO
- Airborne - AUTO/AUTO/AUTO accomplished on the after T/O flow

(767ER) if flaps 25 or 30 selected and ovrspd occurs, the flaps will retract to 20. The flaps will return to the lever selected position novel the speed decreases blw flap placard limit spd.

Both sys’s are energized in flt and deactivated on the gnd through air/gnd logic.

97
Q

Describe the operation of the rudder ratio system?

A

Uses the left hyd sys press to reduce deflection (based on airspeed)

Rudder Ratio
- The control commands from the rudder pedals and trim control are modified by a rudder ratio changer. As airspeed increases the ratio changer desensitized these inputs from the pilot to reduce the rudder deflection. The ratio changer receives air data computer airspeed inputs and provides control commands to an actuator powered by the L HYD SYS. The actuator then dampens the pilots inputs to the rudder.
