Visual flight rules (VFR) flight standard squawk code used in North American airspace when no other has been assigned or is applicable. [7] [3] 1201 US: Assigned via FAR 93.95 for use by VFR aircraft in the immediate vicinity of LAX. [3] US (Visual flight rules (VFR) glider operations for gliders not in contact with ATC, through February 2012 ...
Communication, navigation and surveillance / Air traffic management [12] CODEC Coder/decoder CofA Certificate of airworthiness: COMM or COM Communications transceiver, Communications receiver, or Communications radio transmitter: Now, normally: either VHF or UHF; HF communications avionics are usually abbreviated simply HF CORSIA
A pilot may be requested to squawk a given code by an air traffic controller, via the radio, using a phrase such as "Cessna 123AB, squawk 0363". The pilot then selects the 0363 code on their transponder and the track on the air traffic controller's radar screen will become correctly associated with their identity.
An equipment code describes the communication (COM), navigation (NAV), approach aids and surveillance transponder equipment on board an aircraft.These alphabetic codes are used on FAA and ICAO flight plan forms to aid flight service station (FSS) personnel in their handling of aircraft.
While flying VFR-on-top, pilots are required to stay in an appropriate VFR altitude, maintain the required VFR visibility and cloud clearance requirement, while comply with other IFR requirements (minimum IFR altitudes, position reporting, radio communications, course to be flown, adherence to ATC clearance, etc).

Radio call signs are a globally unique identifier assigned to all stations that are required to obtain a license in order to emit RF energy. The identifiers consist of from 3 to 9 letters and digits, and while the basic format of the call signs are specified by the ITU-R Radio Regulations, Article 19, Identification of stations, [5] the details are left up to each country's radio licensing ...
Ground communications outlets (GCO) have been installed at some U.S. airports to provide a means for pilots on the ground to communicate with flight service stations and air traffic control (ATC) facilities for the purpose of filing, opening and closing VFR or IFR flight plans; obtaining weather briefings and clearances; and similar communications.
If the radio failure occurs in visual flight rules (VFR) conditions in an area where radio communication is required, the pilot is expected to continue under VFR and land when feasible. If flying under instrument flight rules (IFR) conditions, and VFR conditions exist or are encountered after the failure, the flight should be continued in VFR ...
