Are the rudder pedals separate or interconnected between the pilots
Interconnected
How to shut off an elevator runaway trim condition….

Do the flaps operate with lost hydraulic power….
No
Can the GND FLAPs be set in flight….
Technically yes, but not allowed
Gust lock set, towing allowed…

What is activated by moving the flap selector to any position….
Energizes the hydraulic system loading valve and energizes the flap control valve to the selected position
Hydraulic failure, flaps extended, what happens….
Flaps may move upward depending on air load
Speedbrakes extended, how are they technically maintained in the extended position….
By trapped fluid in the lines from the control and safety valves
When does the HYD PRESS ON annunciator illuminates during speedbrakes ops….
When the speedbrakes are fully extended
Speedbrakes extended, loss of DC power or loss of hydraulic power….(what happens with speed brakes)….
- loss of DC power: safety valve opens, trapped fluid released and speed brakes blow in trail position
- loss of hydraulic power: speedbrakes remain in extended position unless switch is placed in RETRACT position, the speedbrakes will trail with airflow
Retract speed brakes latest when….
50 ft AGL
Automatic speedbrakes retraction when….
Either throttle is advance above 85% N2 with electrical and hydraulic systems operating normally
Or
By selecting flaps 35° or less
RUDDER BIAS annunciator illuminates when…
