Which type of flight requires a two-way communication radio?

All aircraft entering class C airspace must establish two-way radio communication with ATC prior to entry; explicit clearance to enter is not required, however the controller of Class C space may instruct aircraft initiating communication to “remain outside” the airspace.

What is a two-way radio used for?

A two-way radio is a radio that can both transmit and receive (a transceiver), unlike a broadcast receiver which only receives content. A two-way radio (transceiver) allows the operator to have a conversation with other similar radios operating on the same radio frequency (channel).

What is the importance of radio communication in aviation?

Effective communication is a very important aspect of aviation safety. As the major means of communication between pilots and air traffic controllers (ATC) is through radio communication, verbal communication skills become crucial to the future of aviation safety.

What type of radio communication systems are used in aircraft?

VHF communication radios are the primary communication radios used in aviation. They operate in the frequency range from 118.0 MHz to 136.975MHz.

What is UHF in aviation?

Military aircraft also use a dedicated UHF-AM band from 225.0 to 399.95 MHz for air-to-air and air-to-ground, including air traffic control communication. This band has a designated emergency and guard channel of 243.0 MHz. Radio aeronautical navigation aids (navaids) use other frequencies.

What is considered two-way radio communication?

A two-way radio is a radio that can both transmit and receive radio waves (a transceiver), unlike a broadcast receiver which only receives content. Other two-way radio systems operate in full-duplex mode, in which both parties can talk simultaneously.

Who uses two way radio?

These types of two-way radios or walkie talkies are commonly used by police, fire personnel and paramedics, although they’re commonly seen on recreational equipment too, such as walkie talkies for kids. However, voice-operated transmission (VOX) is replacing Push-to-Talk walkie talkies in some instances.

What is an example of two way communication?

Some of the most common examples of two-way communication systems are the radio, telephone, and computer-aided dispatch systems used by police, fire, and emergency response personnel.

What type of radio waves are used in aviation?

[Figure 5] Most aviation communication and navigational aids operate with space waves. This includes VHF (30-300MHz), UHF (300MHz-3GHz), and super high frequency (SHF) (3Ghz-30Ghz) radio waves. VHF communication radios are the primary communication radios used in aviation.

What is the purpose of a two way radio?

In some cases, two-way radio is used to communicate analog or digital data. Systems can be simplex or duplex and may employ selective calling features such as CTCSS. In full-duplex systems, data can be sent real-time between two points.

What should a pilot do if there is two‐way radio communications failure?

A pilot experiencing two‐way communications failure should (unless emergency authority is exercised) comply with 14 CFR Section 91.185 quoted below: General. Unless otherwise authorized by ATC, each pilot who has two‐way radio communications failure when operating under IFR must comply with the rules of this section. VFR conditions.

What is a VHF radio used for in aviation?

VHF radios are used for communications between aircraft and air traffic control (ATC), as well as air-to-air communication between aircraft. When using VHF, each party transmits and receives on the same channel. Only one party can transmit at any one time.
