Integrated standby instrument system

Source: Wikipedia, the free encyclopedia.

An integrated standby instrument system (ISIS) is an electronic aircraft instrument. It is intended to serve as backup in case of a failure of the standard

airliners to helicopters and smaller general aviation
aircraft. While it is common for new-built aircraft to be outfitted with ISIS, numerous operators have opted to have their fleets retrofitted with such apparatus as well.

Details

An ISIS is designed to combine the functions of separate equivalent mechanical instruments that had previously been included as backup in such cockpits, including

battery unit), as well as harnessing embedded sensors for its readings wherever possible.[1][2] When all onboard instrumentation is performing normally, the readings indicated by an ISIS are identical to that of the primary flight display.[3] Advantages presented by ISIS over traditional systems include improved safety, greater ease of operation, and reduced operating costs.[4]

A number of aircraft have been produced with relatively sophisticated integrated standby systems which may include additional functions. For example, the

GE Aviation, Smiths Group, and Meggitt, have also marketed ranges of standby instrumentation using both standalone and ISIS-compliance principles.[11][12][13]

Several companies have produced

Airbus Group.[14] In addition to such technology being adopted upon new-build aircraft, several operators have opted to retrofit their existing aircraft fleets with current generation ISIS, such as UPS's Airbus A300 freighters.[15] Along these lines, Rockwell Collins developed a retrofit package for the Boeing 757 and Boeing 767 that incorporates ISIS.[16] During the 2010s, the cost of performing such cockpit display retrofits reportedly dropped substantially.[17]
