First of all,make it clear that we can carry walkie-talkies on a plane. However, when we go through airport security, we need to cooperate with the security officer by switching off the walkie-talkie and removing the battery from the radio and carrying it separately from the main unit. It is also important to note that the walkie-talkie cannot be switched on and used on the aircraft.

The aviation communication system is very important and is mainly used to realize in-flight communication, traffic control, communication with other aircraft, long-distance communication tasks, ground towers calling and contacting aircraft through high-frequency communication systems, aircraft communication addressing and reporting, exchange of flight and maintenance data information and aircraft accident investigation roles between aircraft and ground stations.

The UHF/VHF band of the walkie-talkie has a particularly high impact on aviation communication systems. The frequency of the walkie-talkie in the VHF band is basically close to the aviation communication frequency, and the transmitting power of the walkie-talkie is also very high.In conclusion, walkie-talkies are allowed to be taken on board，but it cannot be used on the aircraft.
