Discusses the requirements for refuelling civil airliners, particularly under pressure refuelling. Analyses the problems that can arise and demonstrates how advancing technology has changed the appearance and efficiency of many components, particularly with reference to the control panel. Describes in detail the workings of a typical system; aspects of control of fuel quantity in refuelling; refuel control panels; and fuel gauges, with particular reference to the Boeing 777.

Compares the features of the 1995 Boeing 777 with its predecessors, highlighting the increased use of digital technology. Emphasizes the much improved reliability of the on‐board maintenance system and describes the sophisticated built‐in fault reporting and test capabilities.

Reports on a recent review of service experience relating to health and usage monitoring of rotorcraft transmission systems. Describes trials of integrated HUMS on military helicopters and an operator's experience using EuroHUMS on Super Puma helicopters. Informs on the vibration monitoring role of integrated HUMS. Notes the values of usage monitoring as distinct from health monitoring.

Summarizes the RAF's need to keep aircraft in service for longer. Provides details of present anti‐corrosion methods employed and explains the RAF's involvement in design and manufacture of the aircraft, as this is where problems begin. Discusses the various forms of training in corrosion provided to those in the RAF, before examining corrosion prevention. Finally, discusses various non‐destructive tests used.

Looks at how Avro International Aerospace deals with the production of aircraft. Examines facilities and production at its Woodford, Manchester‐based site, as well as its potential. States that Avro bases its business activities around three key processes: customer, product and supply. Concludes that it is the attention given to these by all departments in the organization which underline Avro's successful sales position worldwide.

Describes the future air navigation system known as the Communication, Navigation and Surveillance/Air Traffic Management System, which is to be used throughout the world to organize better the increasing volume of air traffic. Details, in particular, automatic dependent surveillance, the facility used to optimize flight paths; and the Aeronautical Telecommunications Network.

Shows how the technology developed for military Head Up Displays is now adopted for civil aircraft. Marconi Electronics with the HUD 2020 has used the ability to present information to the pilot within the forward field of view to enhance the civil pilot’s awareness in high workload situations. This enables precise control of speed and attitude to be obtained down to touchdown.

Explains the development of an ultrasonic fuel gauging system by Smiths Industries in response to Boeing’s desire for a system which offers greater reliability. Looks at components and considerations and discusses current developments.

Typical passive and active vibration reduction systems are dealt with, particular emphasis being on the Westland active control of structural response system fitted to all versions of the EH101. In addition, the extensive experience acquired during the evolution of vibration health monitoring on North Sea helicopters is outlined.

Explains the fuel system of the Boeing 777‐200 aircraft. Looks at the system’s features, the fuel feed, the fuel jettison and the flight deck displays in terms of the fuel system.
