Hobbies And Interests
Audio Panel
The audio panel is the central point of communicative activity, localizing all controls and amplifiers within the aircraft. Functioning as the interface for all sound received internally and externally, it enables the pilot to simultaneously alternate between channels, without having to change frequency settings. This gives the pilot the ability to distribute and prioritize communication. Audio panels are available in multiple configurations, incorporating a range of functions such as voice-activated intercoms, music stereo players and satellite radio interfaces.
Transceiver
A transceiver is a two-way radio communication device, comprising both transmitter and receiver sub-systems. Similar to a walkie-talkie, a transceiver transmits and receives communication, using a "Very High Frequency (VHF) Civil Aviation Band" radio wave spectrum, reserved for helicopter air-to-air communication. Both parties must agree on a specific frequency.
Headset and Microphone
To hear and respond to communication carried through the transceiver, helicopter pilots require both a headset and microphone. Headsets vary in styles to suit ranging preferences. Some designs also incorporate "noise cancellation technology," which eliminates distracting ambient noises. Microphones enable the pilot to talk to other parties.
Intercom
An intercom system facilitates communication between the pilot, co-pilot and passengers. Interconnecting with the transceiver, it enables the pilot to interchangeably liaise between Air Traffic Control (ATC) and those within the helicopter. Provided all on board are wearing headsets, this overcomes physical inhibitors such as a loud aircraft environment and the fact that the pilot is required to wear a headset at all times to talk to ATC. Some intercom systems can also be configured to support incoming and outgoing private telephone calls.
