VHF (Very High Frequency) communication on aircraft refers to the use of radio waves in the range of 118 MHz to 137 MHz for communication between the aircraft and air traffic control (ATC) towers. This allows for two-way communication between the pilot and ATC, as well as communication with other nearby aircraft.
VHF communication on an aircraft works by using a VHF radio transceiver, which is a device that both transmits and receives radio signals. The pilot uses the radio to transmit their voice to the ATC tower, and the tower uses their own VHF radio to respond. The radio waves are then transmitted through the air and received by the other party's radio.
VHF communication on aircraft allows for clear and reliable communication between the pilot and ATC, which is crucial for safe and efficient air traffic control. It also allows for communication with other aircraft, which can help prevent collisions and facilitate coordination during flights.
One limitation of VHF communication on aircraft is its line-of-sight nature, meaning that the pilot and ATC tower must have a direct line of sight with each other for the radio waves to be transmitted and received. This can be a challenge in mountainous or remote areas. Additionally, VHF signals can be affected by interference from other radio transmissions or atmospheric conditions.
VHF communication on aircraft is regulated by the International Civil Aviation Organization (ICAO), which sets standards and procedures for air traffic control and communication. In addition, each country has its own regulatory authority that oversees VHF communication on aircraft within their airspace.
