What does the white box and black box in the test mean?

"Black box" comes from the common name of the flight recorder. Because in some accidents, the recorder is easy to turn black in fire, people regard the flight recorder as a "black box", which is one of the electronic recording equipment dedicated to aircraft.

Refers to two different methods or strategies in software testing: white box testing and blue box testing. White-box testing is also known as structured testing, transparent testing or code-based testing.Under this method, software developers can view and understand the code, structure and implementation details inside the tested system.

Black box is the common name of electronic flight recorder. An instrument used to record aircraft flight and performance parameters. It is not black, but orange. It does not look like a box, but like a streamlined container. It is a sealed container of 1/3 to 1/4 the size of an ordinary drawer.

What is the core part of the system of human and aircraft communication

It is a radio communication system. Radio communication systems include VHF system, HF system, selective call system, satellite communication system and ACARS system. Human-machine systemUnification refers to a whole system composed of two subsystems of interacting and interdependent people and machines in order to achieve a certain predetermined purpose.

However, because the main core components of the teletransmission control system are electronic components, especially digital components, they are extremely vulnerable to electromagnetic interference and lightning shocks. While developing the teletransmission control system, the research of the optical transmission control FBL (Fly-By-Light) system has been further carried out. Investigate. The optical transmission control system is a system that uses optical fiber to transmit signals.

The core part of interpersonal communication is cooperation and communication. Cooperation refers to the unity of individual interests and overall interests through coordination, reasonable division of labor, information sharing, resource complementarity and other ways when people achieve common goals.

Air traffic control Air traffic control is the most core part of ATMs.It is to ensure the safe flight of the aircraft in the air and avoid collisions in the air.

Data processing and analysis system: used to process and analyze the collected data, including artificial intelligence, big data analysis, machine learning and other technologies. Data transmission and communication system: used to transfer data between various components, including network equipment, communication protocols, data transmission protocols, etc.

System composition of aircraft communication addressing and reporting system

1. On the aircraft, the ACARS system consists of an atronics computer called ACARS management unit (MU) and a control display. Unit (CDU) composition. MU is used to send and receive very high-frequency radio digital messages from the ground.

2. The wireless communication system is composed of three major parts: sending equipment, receiving equipment and transmission media (wireless channel). It uses wireless electromagnetic waves to realize the system of information and data transmission. The functions of each part are as follows: sending equipment (1) converter (energy converter): convert the transmitted information into electrical signals.

3. The communication system is roughly composed of three parts: sender (sender and sending device), channel receiving device (sender and receiving device), and noise source. The source is the source of information, and its function is to convert the original signal into the corresponding electrical signal, that is, the baseband signal.

4. The basic components of the communication system are shown in the figure below: source: information source that sends various information (language, text, image, data), such as people, machines, computers, etc.Channel: the transmission carrier of the signal.

5. Communication system of American F-14 fighter jets: AN/ARC-51 and AN/ARC-159 ultra-high frequency AM radio communication radio transceiver; AN/ARR-69 super FM auxiliary radio communication radio receiver, KY-28 password system, LS-46 0/B in-machine caller.

6. Communication system refers to a system that uses electrical signals (or optical signals) to transmit information, also known as a telecommunications system. A system is usually an organic whole composed of several units with specific functions, interactions and interdependence to achieve a unified goal. The simplest communication system is for two-point users to send and receive information to each other.

What does ACAS mean

CAS number is the chemical registration number.It is a number. Now each compound that has been found has its own unique corresponding number, just like our ID number. The cas number first appeared in the Chemical Abstracts published by the Chemical Digest Society, an organization under the American Chemical Society.

A surface refers to A-level surface. That is CAS (Class-A-Surface), which is often mentioned in automobile design. In the field of automobile design, this is an extremely important concept and a necessary skill for automobile designers and A-face masters.

It is a graphics technology used to enhance and clarify the image details in the game.

A cas number is divided into three parts in hyphens. The first part has 2 to 7 digits. The numbers in this part are not fixed, and the second part has 2 digits.Numbers, the third part has a 1-digit number as a check code, and its general form is ###aa-aa-a. But no matter what compound it is, it must be composed of at least five digits.

A side is to smooth CAS, which needs to be careful. There are many places to go after learning. You can go to the OEM or design company. There are more outsourced workers, and the salary is calculated by the hour. There is no problem with one or two years of experience of tens of thousands a month. Engineering is different from A-side CAS-side.

Introduction to Aircraft Communication Addressing and Reporting System

1. On the aircraft, the ACARS system consists of an ACA The aerotics computer of the RS management unit (MU) is composed of a control display unit (CDU). MU is used to send and receive very high-frequency radio digital messages from the ground.

2. Aircraft Communications Addressing and Reporting System (abbreviated as ACARS) is a kind of communication between aircraft and ground stations. A digital data chain system that transmits short messages (messages) by radio or satellite.Simply put, it is a whole set of communication systems between the plane and the ground.

3. This function enables flight personnel to process more types of information, including obtaining various types of information from the ground and sending various types of reports to the ground. For example, a pilot wants to get meteorological information about a certain location.

4. Typical terminal systems include flight management system (FMS), data link printer, maintenance computer, and cockpit terminal. Its applications include: FMS - Send flight plan change requests, location reports, etc. Receive commands to clear the field and control the tower. Printer - locate and automatically print an upload message.

Terminology of Aircraft Communication Addressing and Reporting System

ACARSAircraft Communications Addressing and Reporting System, aircraft communication addressing and reporting system. ACCArea Control Center, Regional Control Center ATSAir Trafific Service, Air Traffic Service ACMSAircraft Condition Monitoring System, Aircraft status monitoring system.

Although ACARS often appears in descriptions of data-linked devices (a field-replaceable unit in avionics systems), the term actually refers to a complete air and ground system.

Aircraft Communications Addressing and Reporting System (ACARS) is a kind of passage between the aircraft and the ground station. A digital data chain system for wire or satellite transmission of short messages (messages).
