THE ADVANTAGES OF CONNECTING AIRPLANES IN FLIGHT WITH GROUND SYSTEMS

 

Traditionally, maintenance teams have had to wait for the airplane to land to gather enough informa­tion to begin their “parts and planning” to make repairs. Today, by integrating ground-based and airplane-based systems, information can be received and decisions made in real time.

For example, if a flight deck effect fault occurs in flight, the pilot enters the fault information into the Boeing ELB, which then automatically enters the fault code into the fault recording form (see fig. 2). The system is designed to allow the pilot to easily enter the initial fault; additional information can be added during a low workload phase of flight. As soon as the captain electronically signs the fault, the ELB transmits an accurate fault description to the ELB ground control system in the maintenance center and to any other airline organizations that need the information. (Because the fault is automatically correlated to the fault code, the deferral status is auto­mati­cally available.) Even though the airplane might still be several hours from landing, the airline can have people, parts, and equipment prepositioned and ready to make any needed repairs when the airplane arrives.

The flight crew uses the Boeing EFB to access the Boeing ELB. A touch screen and graphical user interface enable crews to enter information quickly and accurately. The ELB can minimize ground delays by providing flight crews with instant access to airplane status, deferred maintenance items, information on recurring faults (i.e., fault history), and other vital information.

This system offers operators a number of additional advantages, including:

Maintenance efficiency. The ELB system allows the pilot to choose faults from a codified list of fault descriptions without typing or writing. Due to flight crew workload, many times the standard fault code is not entered into the paper flight log. The automatic inclusion of standard faults and their fault codes will reduce the rate of NFF removals. The accurate and immediate data the ELB provides can reduce troubleshooting and improve communication throughout the enterprise, helping optimize the maintenance operation. Additionally, by providing a history of Fault Reports and Maintenance Actions, the Boeing ELB allows airlines to analyze fleet trends to proactively address system or component issues.

Operational efficiency. An ELB system can reduce downstream delays through fault forward­ing of pilot eLogbook reports, translating into a reduction of maintenance delays and missed air traffic control slots.

Reduction or elimination of paper documents. Boeing estimates that a Boeing EFB/ELB system can reduce labor costs associated with gathering and maintaining paper forms, as well as data entry costs associated with typing logbook entries into airline maintenance planning or history systems.
