How many elevators are there and how are they powered? - 🧠ANSWER
✔✔2 elevators, one on each side
Each elevator is powered by all three hyraulic systems
What provides artificial elevator feel? How is it powered? How many are
needed? - 🧠ANSWER ✔✔Two artificial elevator feel computers provide
forces to the pilot control columns
Each has its own hydraulic power input
The Left and Center system powers these computers

,Only one computer is needed
What happens if the artificial elevator feel system completely fails? -
🧠ANSWER ✔✔If both artificial feel computers lose hydraulic power, then
there are spring backups in the control columns
How many stabilizer trim control modules are there? How are they
powered? Are they separate? - 🧠ANSWER ✔✔There are two trim control
modules.
They are powered hydraulically from the Left and Center systems
respectively
They typically work in unison when trim inputs are made
What are the three modes of stabilizer trim input? - 🧠ANSWER ✔✔Electric,
alternate, and automatic. All three modes need hydraulic power to actuate
the jackscrew
How is electric trim activated? - 🧠ANSWER ✔✔Via the trim switches in the
yoke

, What is the function of each trim switch in each yoke? - 🧠ANSWER
✔✔One switch applies hydraulic pressure while the other releases the
jackscrew brake. Both must selected in unison in the same direction to
move the stabilizer trim
How does electric trim speed change with airspeed? - 🧠ANSWER ✔✔The
faster the airspeed, the slower the trim speed
Will electric trim disconnect the autopilot? - 🧠ANSWER ✔✔It will
disconnect the autopilot if only one autopilot is operating
If more than one autopilot is operating, electric trim is inhibited
How does the alternate trim system work? - 🧠ANSWER ✔✔Overrides all
other inputs and bypasses the control column cutoff relays, but not the
cutoff switches
Will alternate trim cause the autopilot to disconnect? - 🧠ANSWER ✔✔No
Which has a greater range of stabilizer travel? Electric or alternate? -
🧠ANSWER ✔✔Alternate
