You're in charge of purchasing aviation communication equipment. What do you need to know?

1 Communication modes

Aviation communication equipment can operate in different modes, depending on the frequency, modulation, and protocol used. The most common modes are amplitude modulation (AM), frequency modulation (FM), and digital modulation (DM). AM is used for voice communication on very high frequency (VHF) and high frequency (HF) bands, while FM is used for voice and data communication on ultra high frequency (UHF) and very high frequency (VHF) bands. DM is used for data communication on various bands, such as satellite, microwave, and cellular. Each mode has its advantages and disadvantages, such as range, clarity, interference, and bandwidth.

2 Communication types

Aviation communication equipment can support different types of communication, depending on the purpose, audience, and priority. The most common types are air-to-air, air-to-ground, and ground-to-ground communication. Air-to-air communication is used for coordination and safety between aircraft, such as formation flying, traffic advisory, and emergency assistance. Air-to-ground communication is used for guidance and control between aircraft and air traffic control, such as flight plan, clearance, and instruction. Ground-to-ground communication is used for service and support between aircraft and ground services, such as fuel, maintenance, and baggage.

3 Communication features

Aviation communication equipment can offer different features, depending on the functionality, usability, and reliability. Some of the features are essential, while others are optional or desirable. Some of the essential features are frequency range, channel selection, volume control, squelch control, and intercom. Some of the optional or desirable features are dual watch, scan, memory, display, backlight, audio output, noise reduction, encryption, and GPS.

4 Communication compatibility

Aviation communication equipment can vary in compatibility, depending on the mode, type, and feature. You need to ensure that the equipment you buy is compatible with the equipment you already have, the equipment you plan to have, and the equipment you need to communicate with. You also need to consider the compatibility with the power source, the antenna, the headset, and the wiring. You can check the compatibility by reading the specifications, manuals, reviews, and forums of the equipment.

5 Communication regulations

Aviation communication equipment can be subject to different regulations, depending on the country, region, and authority. You need to comply with the regulations that apply to your operation, such as licensing, certification, testing, inspection, and maintenance. You also need to follow the rules and procedures that govern the use of the equipment, such as frequency allocation, call sign, phraseology, and etiquette. You can find the regulations by consulting the official sources, such as civil aviation authority, international civil aviation organization, and radio communication agency.

6 Communication standards

Aviation communication equipment can adhere to different standards, depending on the quality, performance, and interoperability. You need to choose the equipment that meets or exceeds the standards that are relevant to your operation, such as safety, security, and efficiency. You also need to update the equipment that becomes obsolete or outdated due to the changes or improvements in the standards, such as technology, protocol, and format. You can identify the standards by referring to the documents, labels, codes, and symbols of the equipment.
