Read full description

Honeywell’s Forge Maintenance Advisor app is a tool for retrieving Fault History Database (FHDB) or Aircraft Condition Monitoring (ACM) files from the Honeywell Primus® Epic/Apex Integrated Avionics Suite when connected to the aircraft network via the Wireless Data Loader or Aspen Gateway. This app decodes FHDB files on the Honeywell Ground Server and enables the aircraft maintainer to view stored messages of FHDB files to derive meaningful insights about the health of the aircraft. Hon Forge Maintenance Advisor simplifies the way a maintainer uses FHDB data by providing a graphical and visual representation of messages and their occurrences. The app syncs the FHDB data between the iPad and Honeywell Ground Server (Maintenance Advisor web application) for seamless operation. Forge Maintenance Advisor has two interfaces as listed below: 1. iPad application – used by the aircraft line maintainer to view the decoded messages with the Forge Maintenance Advisor app. 2. Web application – decodes FHDB files and is used by the airline tech specialist to view the decoded messages on the web portal to derive meaningful insights on the fleet level health of aircrafts. This enables the user to plan/issue the maintenance activities for the aircraft/fleets.

Read full description

The Pratt and Whitney Digital Engine Services (DES) team developed the Data Collection and Transmission Unit (DCTU) application to communicate with the DCTU hardware on the PT6 E-Series™ engine using wireless connection to perform maintenance actions such as: – View/Change electronic engine control (EEC) and DCTU parameters – Retrieve Events, Exceedances & Faults (EEF) – Retrieve EEC diagnostics data via DCTU – Monitor health status on DCTU – Perform live data diagnostics on DCTU and EEC – Perform test transmission from DCTU to the ground station – Change engine modules by barcode scanning (or) through Manual entry – Change Line Replacement Units (LRUs) by barcode scanning (or) through Manual entry – Supports to do a BOV(Bleed of Valve) closing point check along with the Bluetooth pressure transducer – Allows user to generate locally stored file to enter data related to LRUs and Engine Modules while not connected to DCTU The DCTU hardware provides the capability for the operators to collect data in real-time, record the data to non-volatile memory, make connections to ground support equipment, either wired or wirelessly, and offload data to the ground support equipment.
