In Flight Entertainment

The In Fight Entertainment (IFE) system is one of the most crucial systems as far as the brand equity of an airline is concerned, since it directly impacts a passengers' comfort during long haul flights. The maintenance of these systems is becoming extremely critical as airlines strive to up the ante in order to maintain a competitive edge in the passenger transport business.

Video On Demand, Internet Access, Satellite Telephony, Interactive Games and In Flight Telephony are the value-added services that airlines are adding to their regular offering of Music and Movies on passenger seats. However this has resulted in IFE systems becoming complex and more expensive to maintain.

Capabilities and Services:

The PIA Engineering Complex has a dedicated team of avionics engineers and technicians who are responsible for installations, modifications, and maintenance of the Matsushita/Panasonic MAS-2000E and MAS-3000 E/I systems. This team works in conjunction with the Base Maintenance teams to ensure that IFE installations and modifications are dealt with during major checks, along with the rest of the modifications, service bulletins and airworthiness directives due on an aircraft. As a result, a PIA Engineering customer gets a comprehensive and economical package deal, as well as a reduction in maintenance time, especially if all these activities were undertaken separately.

PIA Engineering undertakes full IFE checks and minor seat rectification during transit checks in conjunction with the Line Maintenance teams. Aircraft engineers and technicians can undertake full seat electronics box removals, installations and data loading in very short time spans, ensuring that all onboard passengers have an enjoyable flight. The team ensures that operators' transit and turn around checks do not exceed their time limitations. PIA Engineering also has the capability to undertake transit checks for the B-747-200/300, B-777, B-737, A-310 and A300B4 under CAA, Pakistan at its base in Karachi, which is a major regional hub.
