Question

The continuous broadcasting of recorded information

for arriving and departing aircraft on a discrete VHF/UHF
frequency. Its purpose is to improve controller and flight
service specialist effectiveness and to relieve frequency
congestion by automating the repetitive transmission of
essential but routine information.

Answer 1

An automated system broadcasts recorded information for aircraft on VHF/UHF frequencies to improve air traffic control efficiency and manage frequency congestion. VHF ranges from 54 to 88 MHz and 174 to 222 MHz, whereas UHF covers 470 to 1000 MHz.

Step-by-step explanation:

The continuous broadcasting of recorded information for arriving and departing aircraft on a discrete VHF/UHF frequency is a vital aspect of air traffic control and aviation communication. The frequency modulation (FM) is used to relay this information on electromagnetic waves, ensuring that pilots receive constant updates about airport conditions without overloading communication channels. This system is designed not only to increase the efficiency of controllers and flight service specialists but also to manage frequency congestion by automating repetitive information about essential but routine details. VHF (Very High Frequency) and UHF (Ultra High Frequency) are the bands used for these broadcasts, with VHF covering 54 to 88 MHz and 174 to 222 MHz, and UHF covering a higher range of 470 to 1000 MHz.
