Study Notes

Overview

This document provides detailed information about Airbus aircraft, focusing on flight safety and efficiency principles, cockpit design, pilot interactions with automation, procedures, and error management.
It covers the Airbus family of fly-by-wire aircraft (A320, A330, A340, A380).
The document explores various aspects of the system design and operation.

Key Principles for Safe and Efficient Flights

Golden Rules for Pilots: Prioritize actions in the sequence of Fly, Navigate, Communicate (FNC).
Appropriate Automation Levels: Use the Flight Mode Annunciator (FMA) to adjust automation levels based on the flight phase and situation. Take action if deviations occur.
Safe and Efficient Flight: Integrate cockpit philosophy, procedures, and human factors, while prioritizing safety, passenger comfort, and efficiency in that order.

Airbus Cockpit Design Principles

Cockpit Layout: Panel arrangement optimizes pilot access and system use frequency.
Automation Levels: Three levels of automation support direct, short-term, and long-term flight operations.
Dark Cockpit Concept: Minimizes visual clutter during normal operation. Color-coded alerts indicate system status.
Fly-By-Wire (FBW): Eliminates mechanical linkages for enhanced safety and reduces weight. Control laws (e.g., load factor, overspeed) ensure safety.

Pilot Interactions with Automation

Side Stick Operations: Ergonomic design and clear cockpit view optimize pilot control.

Airbus Procedures for Safety and Efficiency

Standard Operating Procedures (SOPs): Defined procedures for each flight phase and task.
Supplementary Techniques: Address special situations (e.g., deicing, anti-icing). "Read and Do" methods organize actions.
Abnormal and Emergency Procedures: Define actions for critical situations like system failures, fires, and forced landings.

Introduction to the A320

Aircraft Features: Advanced single-aisle aircraft with fly-by-wire, two CFM International or International Aero Engines engines.
Performance: Specific range and maximum takeoff weight (MTOW) values are provided.
Passenger Capacity: Typical and high-density configurations for passenger seating.
Additional Features: Options for additional fuel tanks and specific runway turn capabilities are discussed.
Design and Unpressurized Areas: Tail cone, main gear, air conditioning, etc.
Cargo Compartments: Specified cargo compartments are described, including forward, rear, and bulk sections.
Cockpit Overview: Two-person glass cockpit, 6 LCD displays.
Ergonomics: Adjustable pilot seats and clear visibility are key factors.
System Panels and Instrumentation: Describes overhead panel functionality for system checks and procedures.

Overview Air Con

The A320 AC system is fully automatic and designed for comfort and efficiency.
It is equipped with two air conditioning packs in the wing-root area, forward of the landing gear bay.

Air Conditioning Packs

Functionality: Hot bleed air regulates flow rate, bypass valve mixes temperatures, and AC machine cools air.
Control: Pack flow and bypass valves are regulated by ACS controllers; ram air flaps are for specific conditions.
Failure Protocol: Emergency ram air valve provides ventilation in case of pack failures.
Monitoring: Parameters like flow, temperature, and valve positons are displayed on the ECAM.

Cabin Air Recirculation

Cabin fans recycle air.
Fans establish recirculation into mixing unit (controlled by the ventilation panel).
Efficiency is improved.

Pre-Flight Setup and Pack Activation

Initial Setup: Confirm all overhead panel buttons ("lights out" configuration).
Activating Packs: Check for any amber fault lights (normal).
Pack Flow Selector: Adjusts flow rates, set to "Normal" for standard loads.

Connecting APU Bleed to Packs

APU Bleed Activation: Activates APU bleed.
Air Supply: Conditions bleed air supply and opens valves.
Temperature Regulation: Adjusts temperature using trim air valves, depending on the desired temperature.

Engine Start and Bleed Priority

Engine Start Sequence: Describes steps for engine start, including pack valve operation and APU bleed air allocation.
Post-Start Behavior: Following engine start, pack valves reopen, and APU bleed air resumes supplying packs.
Performance Optimization: Engine bleed is maintained until the aircraft is on performance-limited runways.

Scenario: Pack Overheat During Cruise

Context: Describes a specific scenario where a pack overheat occurs during normal cruise.
Indications of Overheat: Failure messages, amber indications on the ECAM bleed page, and flashing lights on the panel.
Caution Trigger: Details when the overheat caution is triggered; exceeding temperature limits and repeated crossings of the amber threshold (four times during the flight).
Automatic Response: Pack Flow Valve automatically closes to protect the pack, and the panel displays an amber indication to show the disagreement.
ECAM Procedure for Pack Overheat: Defines actions to reduce the overheat and restore normal operation. Turning pack 1 off and back on is included.
Additional Abnormal Scenarios: Further scenarios related to using the ram air push button are mentioned, showing indications and handling.

Other Components and systems

Various other systems and components are discussed, including cargo conditioning, pressurization, ventilation, electrical, fire detection/extinguishing, fly-by-wire (FBW) systems, landing gear/braking/steering, oxygen systems, and other relevant details, including detailed descriptions of failures and troubleshooting.
Detailed information on the A320's navigation system (ADIRS, NAVAD, and DDMI) along with related operation and maintenance procedures are also examined.
The document includes detailed descriptions of the A320's ground proximity warning system (GPWS) and the TCAS (Traffic Collision Avoidance System) procedures, as well as the aircraft's communication system, details on the cockpit voice recorder, and operations.
Other considerations on the A320 include the essential components and the electrical system including the overall electrical design and its components, additional power sources (e.g. APU and emergency generator) and procedures, along with the detailed ECAM displays, checks during pre-flight and during operations, and emergency procedures.
Data is provided regarding the A320 flight deck, including design philosophy, electronic instruments, features, and additional features of the flight deck design and configuration.
