In civil aviation, very high frequency (VHF) amplitude modulated (AM) radio is typically used for radio voice communication between personnel in the cockpit and personnel in the air traffic control tower. VHF AM radio utilizes "simplex" (also called "half duplex") mode: i.e. a particular channel is used for both sides of a two-way conversation, and only one party can talk at a time (also known as "two way radio").  4, record 1, English, - simplex

Two definitions have arisen over time: a common definition, which is used as an ANSI [American National Standards Institute] standard and elsewhere, and an ITU-T [International Telecommunication Union - Telecommunication Standardization Sector] definition. The ITU definition of simplex is termed "half duplex" in other contexts.  5, record 1, English, - simplex

Record number: 1, Textual support number: 5 OBS

According to ANSI standard, simplex also refers to communication that occurs in one direction only, from one device to the next. In the simplex mode, one of the devices can transmit but cannot receive, or it receives but does not transmit. The half-duplex mode indicates a transmission in either direction, but it can take place in only one direction at a time.  2, record 1, English, - simplex

For example, a walkie-talkie is a half-duplex device because only one party can talk at a time. In contrast, a telephone is a full-duplex device because both parties can talk simultaneously.  2, record 2, English, - half%20duplex
