Solutions 2026-2027 Updated.
What are PFCCs and what do they do? - Answer (Primary Flight Control Computers)-
Responsible for the operation of the Fly-By-Wire System and its associated functions. The PFCCs
receive commands from the autopilot/flight director systems and provide flight envelope and
structural protections of the aircraft
How many PFCCs are installed on the aircraft? - Answer 3 identical PFCCs
How many PFCCs are active at any given time? - Answer 1
How many PFCCs are required to have the aircraft operate in Normal Mode? - Answer a. 1
b. The PFCC in control is auto selected at power up c. There is no way to determine which PFCC
is in use during normal mode
AT and FD functionality are provided by which computers? - Answer DMC - Data Module
Cabinet
How many DMCs are on the aircraft? - Answer 2 (left and right, both with dual channels (A and
B))
How many channels are active at a time inside a DMC? - Answer One, while the other is on
standby
How is the selection of the active DMC determined? - Answer Automatically based on odd and
even days
What are the two basic modes? - Answer HDG and FPA
What Is the purpose of the XFR switch on the glareshield? - Answer a. Used to select which
channel (A or B) in the DCU Module Cabinet (DMC) will supply flight guidance.
b. Determines the master FMS
How is the flight director represented on the PFD? - Answer A small magenta circle with lateral
bars
,How is the flight path vector represented on the PFD? - Answer A slightly larger green circle
(than the FD) with lateral bars and a vertical bar
Where should the confirmation of any active mode be made? - Answer On the FMA
What is the minimum altitude for engagement of the AP? - Answer 400' AGL
What is the minimum altitude for use of the AP? - Answer 80' AGL
What is Half Bank Mode? - Answer Limits the maximum bank angle used by the Flight Director
to 15 degrees (normally 30).
How is Half Bank Mode represented on the PFD ? - Answer Green arc on the top edge of the
attitude indicator
Is Half Bank Mode automatically activated in NAV mode? - Answer Yes
When else is Half Bank Mode automatically activated? - Answer When aircraft altitude climbs
through 31,500ft
What does the VNAV mode allow you to do? - Answer It allows the FD to follow FMS vertical
navigation profiles
How can the autopilot be disengaged manually? - Answer a. Pressing the red AP/PTY switch on
the sidestick
b. Pressing the AP pushbutton on the FCP
c. Operating the pitch trim switch on the sidestick
d. Moving the sidestick
e. Moving the tiller or rudder pedals during autoland ground roll
f. Pressing the TOGA pushbutton on the ground for more than 2 seconds
When do the autothrottles engage on the ground? - Answer Thrust levers move past 23
degree Thrust Lever Angle (TLA)
When do the autothrottles engage in the air? - Answer a. AT switch is pressed 16
b. TOGA is pressed
c. EDM is pressed or activated
, d. Go-Around is selected or
e. Windshear escape guidance mode is activated
What are some ways the pilot can deactivate the autothrottle? - Answer a. A/T DISC button on
either thrust lever
b. AT pushbutton on the FCP
c. Moving the thrust levers
What are the indications when the autothrottle disconnects? - Answer a. AT flashes amber in
the middle section of the FMA
b. "AUTOTHROTTLE" sounds
What are the dicerent types of operating modes on the Autothrottle? - Answer HOLD, SPD,
THRUST, EDM, USPD, LIM (amber)
Describe what THRUST mode is? - Answer Autothrottle controls engine thrust to an N1 based
on the current phase of flight. Aircraft is essentially pitching to maintain the airspeed based on
the thrust setting.
Describe what SPD mode is? - Answer The autothrottles maintain the indicated airspeed (or
mach number) selected with the SPD switch on the FCP (manual or FMS).
What happens when the AT mode changes on the FMA? - Answer It flashes green for 5
seconds then becomes steady
The AT operates in takeoff HOLD mode to maintain takeoff thrust in which condition? - Answer
From 60 kt to 400 ft RA
At what altitude does the AT RETARD mode activate? - Answer Activates when the aircraft
reaches approximately 30 ft RA
The FMA is divided into five sections which include from left to right - Answer a. AT mode
b. Lateral modes
c. Autopilot/auto throttle
d. Vertical mode
e. Alternate Data
