discrete frequency

discrete frequency

i. A separate radio frequency for use in direct pilot-controller communications in ATC (air traffic control) that reduces frequency congestion by controlling the number of aircraft operating on a particular frequency at one time. Discrete frequencies are normally designated for each control sector in en route/terminal ATC facilities.
ii. A frequency designated for a specific purpose.
