  • Method and system for measuring system availability for in-flight entertainment systems
    Patent number: 6453267
    Abstract: A method and system of measuring availability of an in-flight entertainment system (“IFE”) on an aircraft. The method comprises designating a subsystem weight factor to each subsystem of said IFE, with the sum of all subsystem weight factors being equal to a predetermined number, selecting at least one element of the subsystem to measure its availability, designating a zonal weight factor for the at least one element based on a predetermined class to be serviced by the at least one element, assigning an element loss factor based on a level of service for at least one element, collecting performance information regarding the at least one element during a predetermined period of time, and measure the element's availability based on the subsystem weight factor, the zonal weight factor, the element loss factor and the level of service.
