Study Notes
Key Differences between Type 3 and Other Systems
- Type 3 systems are distinguished by their specific operational limitations compared to Type 1 and Type 2 systems.
Central Maintenance Computers (CMCs) Functions
- CMCs monitor and diagnose aircraft systems, ensuring optimal operation and safety.
- They store crucial data about aircraft systems in non-volatile memory for reliability.
Guided Tests in the MCDU
- Guided tests assist operators in troubleshooting and maintaining aircraft systems effectively.
CMC Data Storage
- CMCs utilize non-volatile memory to retain aircraft systems data, ensuring preservation during power loss.
Multifunction Control Display Unit (MCDU) Line Keys
- Line keys allow operators to interact with various operations within the MCDU, facilitating system management.
Accessing CMC Functions
- Operators can access CMC functions through the MCDU interface, simplifying control and monitoring.
Consequences of Class 2 Failures
- A Class 2 failure can affect flight operations but typically does not compromise safety or necessitate immediate action.
Class 3 Failures Availability
- Class 3 failures are specific to maintenance scenarios and typically not presented during regular flight operations.
Primary Function of Type 1 System Computers
- Type 1 systems are responsible for critical flight control and navigation tasks.
Type 2 System Computers Output Connection
- Type 2 system computers connect to multiple data buses for transmitting vital information.
Type 1 System Computers Connectivity to CMCs
- They connect to CMCs through dedicated communication links for data exchange.
ECAM STATUS Page Purpose
- The ECAM STATUS page provides real-time information regarding the current health and status of aircraft systems.
ARINC 429 Link Functionality
- The primary function is to ensure reliable data exchange between CMC 1 and CMC 2, enhancing redundancy and system integrity.
Real-Time Warnings on ECAM and MCDU
- Failures such as engine warnings and system malfunctions are displayed in real-time for immediate awareness.
CMCs Non-Volatile Memory System
- Recording failure information in a non-volatile memory system ensures that critical data is retrievable even after power loss.
Warnings on ECAM Display
- Warnings displayed remain active until explicitly canceled, ensuring continuous alertness to potential issues.
Flight Warning Computers Function
- They analyze aircraft data to detect and warn of anomalies affecting flight safety and performance.
Primary Function of ECAM Display
- The ECAM displays operational data and alerts, aiding pilots in monitoring aircraft performance.
Class 1 EFB System Characteristic
- Features primarily support flight operations without direct administrative control for use.
Administrative Control Requirement for EFB Systems
- Class 2 EFB systems require administrative control before they can be utilized in operational scenarios.
Class 1 vs. Class 2 EFB Systems
- Class 1 systems do not require pre-approval for use, while Class 2 systems mandate specific administrative oversight.
Primary Use of Electronic Flight Bag (EFB) System
- EFB systems are mainly employed to manage flight-related documents and improve cockpit efficiency.
Alternative Term for Class 1 EFB
- Some refer to Class 1 EFB systems as Portable Electronic Flight Bags (PEFB).
Document Describing EFB Classes
- The guidelines that outline EFB classes are typically detailed in aviation regulatory documentation.
Ground Support Personnel Interface
- Remote access to the aircraft's server enables ground support personnel to perform diagnostics and updates.
LoadStar Software Function
- LoadStar software is responsible for loading and managing flight data efficiently across various systems.
On-Board Data Loaders on Boeing Aircraft
- Latest Boeing aircraft utilize Dedicated Data Loaders for crucial data management tasks.
Dual Operating System Software
- PMAT/NT supports two different operating systems for versatile operational capabilities.
Connections for Portable Data Loaders (PDL)
- PDLs connect to aircraft systems through ARINC data buses, facilitating data transfer.
On-Board Data Loaders on Airbus Aircraft
- Airbus employs specific data loading systems designed for their aircraft models to streamline data management.
