The passenger equipment includes devices that create comfort conditions of staying of passengers on board of aircraft. The space of passenger onboard is limited by the seat and In-Flight Entertainment (IFE). IFE equipment is a powerful marketing tool and a means to satisfy the whims of passengers in the competition for the customer between different airlines. Especially important role IFE plays on intercontinental flights, creating a psychological relief for passengers. In accordance with this equipment IFE can be classified as the necessary equipment that directly affects the safety of air travel.

The main functions that IFE can provide to passengers:

• Viewing videos and listening to audio media from an electronic library;
• Flight crew communication with passengers;
• Two-way communication with flight attendants;
• Information about flight parameters;
• Ability to watch TV shoes via satellite TV channels;
• Computer games;
• Ability to use a mobile connection;
• Access to the Internet;
• Ability to connect passengers’ equipment.

IFE equipment consists of a sensor monitors placed in a chair or on special sliding mounts, remote controls and headphones. Structure and functions of passenger equipment differ from class of the ticket and airline. Example of passenger equipment for the first class is shown in Fig. 201. Fig. 201. IFE equipment (Emirates’ airlines)

IFE equipment at present is developing very dynamically. Modern IFE equipment during the flight allows shopping, play games, watch TV programs and, most importantly for modern passenger - work and communicate with any part of the world via telephone, e-mail and send fax messages. For busy people such systems are an essential component of precedence onboard of aircraft because they allow creating a working environment [62].

IFE equipment for avionics structure is very complex, difficult, overall and needs a strong power supply. Typical IFE equipment can take place, equivalent to 200 MCU and consume about 100 W of electricity per passenger. In particular, the Rockwell Collins firm offers such IFE equipment [98]:

• I2S;
• digital Programmable Audio Visual Entertainment System (dPAVES);
• digital Total Entertainment System (dTES);
• Enhanced Total Entertainment System (eTES).

For example, eTES consists of server and client equipment that operates on the operating system Windows (Fig. 202). Communication of server hardware with every passenger seating is provided by the high-speed data network. Flight attendants via the interface can enter some information and observe passengers. Moreover, such systems monitor what the passenger is interested in and provide information that may be interested for him.
