When does an armed speed brake lever move to the up position and the spoiler panels raise after landing occur?
- both thrust levers are at idle
- Roll out mode engaged at 5 feet RA
- calibrated airspeed below 80 knots
• both thrust levers are at idle
(767) How does the pitch enhancement system operate?
- The PES uses a PTU driven by the left hydraulic system which uses trapped right trim system fluid to power the stabilizer
- The PES uses the HDG powered from center pneumatic pressure which uses trapped left system fluid to power the elevator
- The PES uses a PTU driven by the right hydraulic system which uses trapped left trim system fluid to power stabilizer trim
• The PES uses a PTU driven by the right hydraulic system which uses trapped left trim system fluid to power stabilizer trim
What does the stab trim light and EICAS message indicate?
- fault in back up mechanical trim system
- Stabilizer trimming is at half the rate
- fault in the Mach speed trim system
• stabilizer trimming is at half the rate
When is Mach speed trim inhibited from trimming?

- When a fault exists in the rudder ratio system• when a yard damper fault occurs
• when electric, alternate, or auto pilot trim is operating
Alternate flap operation allows manual operation of the flaps and slats through electric motors. Extension of the flaps and slats from up to flaps 20 with the alternate system requires approximately __________.
- four minutes
- One minute
- two minutes
• two minutes
(767) With flaps 30 selected and air speed increases above 170 kn, what action should occur?
- The FLAP LD RELIEF EICAS message will display

- all 3 PDU hydraulic shut off valves close
- hydraulic power to only the slats is automatically shut off
• hydraulic power to only the slats is automatically shut off
What is the purpose of the yaw damper system?
- limits rudder deflection during taxi
- modifies pilot aileron inputs above 240 knots

The flight control columns and wheels are connected through jam override mechanisms. If a jam occurs in a column or wheel, how can the pilots maintain control?
- The pilots can maintain control by moving the stabilizer trim cut outs which is to cut out, then returning the operable system to norm
