can be expanded by clicking it with the mouse. This brings a pop-up window with enlarged display picture. Such windows are
standard Flight Simulator pop-up windows. They can be resized, moved to any position and arranged to your taste. You can drag
a window clicking at any place, except for the area in upper right corner - clicking there will close the window. A window can be
undocked by right-clicking it and selecting “Undock” in pop-up menu. This allows the window to be moved outside main FS window
and placed anywhere on desktop, or on second monitor. The same can be done with MCDU pop-up window.
Thrust control
The A320 aircraft thrust levers are different from those found on Boeing-type or other common aircraft. The thrust levers move
through distinct detents, or gates, marked “MREV”, “IDLE”, “CL”, “FLX/MCT”, and “TO-GA”. Takeoff power is applied by moving
the levers to TO-GA or FLX-MCT gate, which commands autothrust system to produce computed takeoff thrust corresponding
to current conditions. At thrust reduction altitude, thrust levers are retarded to CL gate, which automatically engages autothrust
system. From this point, the levers are normally left in CL detent through all the ight until just before touchdown.
Autothrust system controls engine thrust corresponding to active thrust modes and thrust limits. The A320 thrust levers are not
back-driven by autothrust system, and don’t move as the thrust is automatically adjusted. Unless needed, they are left in CL gate
until synthesized voice announces “RETARD” 20 feet above landing runway.
Due to this, thrust control is implemented differently than on other Flight Simulator panels. Instead of using joystick throttle or Flight
Simulator keys, the panel uses custom keys (Numpad PLUS and Numpad MINUS by default) to move thrust levers between gates.
You can also use pedestal view and move levers with the mouse. Thrust levers position can be checked by looking at thrust Flight
Mode Annunciator on PFD, the thrust limit name on E/WD, or by checking the pedestal view.
Manual thrust control is still possible, using joystick throttle or Flight Simulator keys. Make sure that the panel-simulated thrust
levers are left at IDLE, or set at CL but the autothrust is disengaged.
Please check Autothrust discussion in Autoight section of this manual for further information.
Flight controls
The PSS A320 panel attempts to simulate electronic y-by-wire ight control system of the real aircraft. The conventional ight
yokes are replaced on Airbus aircraft with side-sticks, much like a computer joystick. Sidesticks send electronic signals to ight
computers, which drive the control surfaces.
Left-right stick deection controls bank rate, and computers will not allow to exceed bank limits of ±67° bank.
Forward-aft stick deection controls aircraft G load. Neutral stick position commands load of 1 G, resulting in level ight or constant
vertical speed, regardless of airspeed, altitude or weight. This is simulated in PSS panel by auto-trimming the aircraft, although
this can be done only when the joystick is centered.
The joystick inputs to Flight Simulator are disabled when the autopilot is engaged. This is done to prevent joystick noise from
interferring with autopilot operation.

REV 01 SEQ 001 PRIMARY FLIGHT DISPLAY
General
The Primary Flight Display (PFD) is the outer display on Captain and FO panels. It provides information on:
• Attitude and Guidance commands
• Airspeed
• Barometric and radio altitude and vertical speed
• Heading and track
• Flight Mode Annunciations
• Vertical and lateral deviations
The PFD is divided into several sections:
Flight Mode
Annunciations
Attitude and
Guidance
Airspeed Altitude and
Vertical Speed
Heading and
Track
Flight Mode Annunciations
Flight Mode Annunciator (FMA) are indications of current status of FMS operation. The FMA is divided into 5 columns which
indicate:
• Thrust modes
• Active and armed Pitch modes
• Active and armed Roll modes
• Approach capabilities
• Autopilot, Flight Director and Autothrust engagement status
The Flight Mode Annunciations are discussed in detail in Autoight and FCU section.
