General Information/Airbus Operational Philosophy Flashcards
The FCTM provides the flight crew with:
‐ The general Airbus operational philosophy (e.g. design and utilization principles, golden rules for
pilots)
‐ Additional information to the FCOM procedures (the “why” to do and the “how” to do)
‐ Best practices, operating techniques on maneuvers, and handling
‐ Information on situation awareness.
If the FCTM data differs from the FCOM data, the FCOM remains the reference.
The FCTM has 5 sections:
GENERAL INFORMATION
AIRBUS OPERATIONAL PHILOSOPHY
AIRCRAFT SYSTEMS
PROCEDURES
PREVENTING IDENTIFIED RISKS
GENERAL INFORMATION section provides information on:
The FCTM purpose
The FCTM content
The introduction to the Preventing Identified Risks
The abbreviations.
AIRBUS OPERATIONAL PHILOSOPHY section is divided into four sub-sections:
- Design Philosophy:
This sub-section describes the Airbus design and utilization principles of: ‐ The cockpit
‐ The fly-by-wire
‐ The procedures. - Tasksharing rules and communication:
This sub-section describes the general tasksharing and communication rules in normal and abnormal operations. - Management of Abnormal Operations:
This sub-section describes how the flight crew should manage abnormal operations (e.g. Handling of ECAM alerts, QRH, ADVISORY) - Golden Rules for Pilots:
This sub-section describes the Airbus “GOLDEN RULES FOR PILOTS”.
AIRCRAFT SYSTEMS section provides:
supplementary information and operating techniques on the use of specific systems (e.g. BIRD, TCAS)
PROCEDURES section provides
normal and abnormal operations: ‐ Best practices (why to, how to, what if not done)
‐ Maneuvers and handling techniques
This section is divided into two sub-sections:
1. Normal Procedures (including Supplementary Procedures) 2. Abnormal and Emergency Procedures
PREVENTING IDENTIFIED RISKS section
provides the glossary of the identified risks and potential consequences that the flight crew may encounter.
A safe and efficient flight results from an effective interaction between:
‐ The Airbus cockpit philosophy
‐ The procedures
‐ The pilots (human mechanisms and behaviors).
DARK COCKPIT CONCEPT FOR OVERHEAD PANEL
Most of the systems are controlled from the overhead panel via:
‐ Pushbutton
‐ Pushbutton switch
‐ Switch
‐ Knob, knob-selector
DARK COCKPIT CONCEPT FOR OVERHEAD PANEL
The general operational rule is:
Light out philosophy. The systems are ready and fit to fly.
The information provided on the display units is color coded to indicate:
‐ The status of the system (ECAM or FMA)
‐ The status of the mode (FMA)
‐ The nature of the information (e.g. title of an alert, action to be performed, information).
The information provided on the pushbutton/pushbutton switch is also color coded to indicate the status of the system:
‐ Amber: Indicates that a system is failed
‐ Red: Indicates a failure that may require an immediate corrective action
‐ Green: Indicates that a system operates normally
‐ Blue: Indicates the normal operation of a temporarily selected system
‐ White: Indicates the abnormal position of a pushbutton switch or maintenance/test result
indication
‐ Blank: The system is fit to fly.
The information provided on the pushbutton/pushbutton switch is also color coded to indicate the status of the system:
‐ Amber: Indicates that a system is failed
‐ Red: Indicates a failure that may require an immediate corrective action
‐ Green: Indicates that a system operates normally
‐ Blue: Indicates the normal operation of a temporarily selected system
‐ White: Indicates the abnormal position of a pushbutton switch or maintenance/test result
indication
‐ Blank: The system is fit to fly.
The relationship between the pilot input on the sidestick, and the aircraft response, is called the
control law.
The control law determines the handling characteristics of the aircraft.
The purpose of the flight control protections is to:
‐ Give full authority to the flight crew, in order to enable them to obtain the best aircraft performance
with an instinctive, immediate action on the related control
‐ Minimize the possibility of over-controlling, overstressing, or damaging the aircraft.
NON BACK-DRIVEN THRUST LEVER CONCEPT
‐ The flight crew can easily and intuitively monitor the energy of the aircraft via current energy
cues (speed, speed trend, engine parameters), and not via ambiguous
thrust levers movement
‐ When the autothrust is engaged, the Thrust Lever Position determines the maximum authorized
thrust that may be commanded by the autothrust
‐ When the flight crew uses manual thrust, the Thrust Lever Position determines the current thrust
(as on any aircraft not equipped with autothrust).
The flight crew should keep in mind that sidestick inputs are
algebraically added. Therefore dual inputs must be avoided, and will trigger aural and visual alerts.
Either flight crew can make an input on their sidestick at any time.
Either flight crew can deactivate the other flight crew’s sidestick by pressing on their sidestick pb.
When the aircraft is in re-configuration law, the flight crew should consider the following:
‐ At high altitude, descend to a lower altitude to increase the margin to buffet. Descending by
approximately ___ reduces significantly the occurrence of stall warning
in turbulence.
4 000 ft below REC MAX ALT
Depending on the
re-configuration law, the pitch control law can have different modes, but the roll control law will always be in
direct law.
DIRECT LAW
The PF must avoid performing large thrust changes, or sudden speedbrake movements, particularly if
the center of gravity is aft.
MECHANICAL BACKUP
In such cases, the objective is not to fly the aircraft accurately, but to
maintain the aircraft attitude safe and stabilized, in order to allow the restoration of lost systems.
SOP UTILIZATION PRINCIPLES
The flight crew should perform SOP actions by memory. The flight crew can also decide to refer to the QRH, in order to perform both
the Preliminary Cockpit Preparation and Securing the Aircraft procedures.
The not-routine tasks are supported by the Supplementary Procedures. The flight crew must perform not-routine actions, using
the READ & DO principle.
For Supplementary Procedures, the flight crew should use the following tasksharing: If the procedure is related to engine start, it is recommended to
read the entire
procedure first, and then:
‐ The PM reads the actions, and
‐ The PF acts on the controls.
