問題一覧

is the most common communication medium used in an aircraft or in the aviation industry. It is used by the cabin crew, aircraft technicians, pilots, and flight attendants who use this medium to take care of and communicate with the passengers.

Verbal Communication

involes the use of gestures, facial expressions, body language, eye contact, posture, and other physical cues to convey messages.

Nonverbal Communication

involves conveying messages through written words.

Written Communication

uses visual elements such as images, graphics, charts, diagrams, maps, videos, and animations to convey information.

Visual Communication

encompasses various forms of communication conducted using electronic devices and technology.

Digital Communication

It is when the pilot communicates with the achine in the form of a command and that message gets transmitted to other machines.

Human-Machine Communication

This is the most common type of aircraft communication. It is used to communicate between aircraft and air traffic control (ATC).

Air-to-ground Communication

This is used for communication between crew members on the same aircraft. It is used to coordinate flight activities, share information, and to communicate with passengers in an emergency.

Interphone Communication

This is used for communication between cabin crew members and passengers. It is used to provide announcements, answer questions, and to respond to emergencies.

Cabin Communication

is the most common technology used for aircraft communication.

Radio

is a newer technology that uses digital signals to transmit data between aircraft and ground stations.

Datalink

can be used to provide aircraft communication over long distances, even in areas where radio signals cannot reach.

Satellite

electromagnetic in nature and part of the electronic spectrum. The atmosphere is filled with these waves.

Radio Waves

consists of a precise oscillating circuit or oscillator that creates an AC carrier wave frequency. This is combined with amplification circuits or amplifiers.

Transmitter

Antennas are simply conductors of lengths proportional to the wavelength of the oscillated frequency put out by the transmitter. An antenna captures the desired carrier wave as well as many other radio waves that are present in the atmosphere.

Receivers

a communication radio that transmits and receives The same frequency is used for both. When transmitting, the receiver does not function. The push-to-talk (PTT) switch blocks the receiving circuitry and allows the transmitter circuitry to be active.

Transceiver

are conductors that are used to transmit and receive radio frequency waves.

Antennas

This is the basic method of navigation where pilots use visual references on the ground, such as landmarks, roads, rivers, and coastlines, to navigate. While this method is still used, it's often supplemented by more advanced techniques for accuracy.

Pilotage

This method involves estimating an aircraft's current position based on its previously known position, course, groundspeed, and elapsed time.

Dead Reckoning

transmit non-directional signals that can be used to determine an aircraft's direction from the station. They are less accurate than VORs and can be affected by atmospheric conditions.

Non-Directional Beacon

provides the distance from the aircraft to a ground station equipped with DME. It's often used in conjunction with VOR for accurate navigation.

Distance Measuring Equipment

stations transmit signals that allow pilots to determine their radial position relative to the station. By referencing two VOR stations, pilots can triangulate their position.

VHF Omni-Directional Range

is a satellite-based navigation system that provides accurate position, velocity, and time information.

Global Positioning System

These systems use accelerometers and gyroscopes to continuously calculate an aircraft's position, velocity, and attitude relative to an initial reference point. INS is highly accurate but can drift over time without external updates.

Inertial Navigation Systems

is a computerized system that integrates various navigation data, including-GPS, radio navigation aids, and aircraft performance parameters. It helps pilots plan and manage their flight routes more efficiently.

Flight Management System

allows pilots to fly specific paths based on latitude and longitude coordinates rather than being limited to following ground-based navigation aids.

Area Navigation

defines the level of accuracy and performance required for a specific flight operation. It's often used for precision approaches and navigation in congested airspace.

Required Navigation Performance

These are digital devices that replace traditional paper charts and documents, providing pilots with up-to-date navigation information, charts, weather data, and more.

Electronic Flight Bags

A type of radio communication that uses radio waves in the frequency range of 3 to 30 MHz.

A type of radio communication that uses radio waves in the frequency range of 30 to 300 MHz.

VHF

is a range of frequencies within the electromagnetic spectrum. It is divided into many different bands, each with its own characteristics and uses.

Frequency Band

is the exchange of information between aircraft and ground stations, or between aircraft themselves. It is an essential part of safe and efficient air traffic operations.
