Study Notes

Data Communication Overview

Data Comm revolutionizes communication between air traffic controllers and pilots by enabling data message transmission rather than traditional voice communications.
Voice communication was prone to miscommunication and errors, often resulting in lengthy exchanges.
Data Comm enhances safety, speeds up communication, and allows simultaneous instructions to multiple aircraft.
Reduces travel delays significantly, enabling planes to receive rerouting instructions quickly.

Data Comm Implementation

Operational at 65 air traffic control towers, significantly under budget and ahead of schedule.
Original 55 airports expanded to 62 due to budget savings.
Initial Operational Capability (IOC) declared at four Air Route Traffic Control Centers (ARTCCs): Kansas City, Indianapolis, Minneapolis, and Atlanta.
Eight additional sites operational 24/7, pending IOC declaration.

International Standards Organizations

International Organization for Standardization (ISO): Develops global standards for safety, quality, and interoperability across various sectors.
ISO membership includes over 160 national standards bodies, ensuring representation and consensus in standard creation.

ISO Standard Creation Process

Proposal Stage: Industry groups request new standards.
Preparatory Stage: A working group drafts the standard.
Committee Stage: Optional review and consensus among committee members.
Enquiry Stage: Draft is distributed for comments; becomes Draft International Standard (DIS).
Approval Stage: Final Draft International Standard (FDIS) voted on by ISO members.
Publication Stage: Approved FDIS published as an official ISO standard, requiring two-thirds approval.

ISO Certification

Assurance from certifying bodies that products or systems meet ISO standards.
Certification terminology should specify the relevant ISO standard rather than using "ISO certification."

Consultative Committee for International Telephony and Telegraphy (CCITT)

Develops recommended standards for telephone and telegraph communication in the U.S.

Institute of Electrical and Electronic Engineering (IEEE)

U.S.-based professional organization focused on electronic, computer, and communication engineering standards.
Promotes safety, interoperability, and sustainability through technology standards.

Electronic Industries Association (EIA)

Establishes and recommends industrial standards, can be proposed by businesses for market-specific needs or by government regulations.

Components of Data Communication

Message: The critical asset, which can be text, audio, or video.
Sender: The device transmitting the message (e.g., computer, mobile phone).
Receiver: The device that receives the message (e.g., computer, telephone).
Transmission Medium: Physical path (wired or wireless) through which messages travel (e.g., cables or radio waves).
Set of Rules (Protocols): Established rules for communication between devices; essential for ensuring successful data exchange.

The Internet

A global network of interconnected computers, servers, phones, and smart devices using Transmission Control Protocol (TCP).
Facilitates the fast exchange of information and files across different hardware technologies.

Communication Services

Services enabling lawful transmission of data, including voice, audio, video, and Internet transmission across various networks.

File Transfer Services

Facilitates the exchange of data files across networks. Examples include Dropbox, Google Drive, and Apple's cloud services offering storage and collaboration features.

Directory Services

A database system designed for storing and maintaining information about users and resources in a network.
