MyEngine vs DCTU

Overview Williams International - MyEngine - Information File Transfer This application facilitates the transfer of Engine Information (e-info) files from an Aircraft to Williams International. The MyEngine application has 2 Connection Modes, Aircraft and WI. In Aircraft Connection Mode the flight files on the Aircraft are acquired by the iPad. In WI Connection Mode, the e-info files are uploaded to Williams International. Acquiring Aircraft Files In order to acquire Aircraft flight files, change to Aircraft Connection Mode. Use the [ Make a Connection ], [ Connect to Aircraft ] or [ Connect to Internet ] button on the home page to access the iPad Settings (Wi-Fi) and select the appropriate Aircraft network. Once the Aircraft Wi-Fi setting is selected, return to the MyEngine home page and verify Aircraft availability via the [ Wi-Fi ] display. Aircraft file acquisition will begin automatically. Aircraft files can be re-acquired, or a cancelled acquisition can be restarted, by using the [ Retry Transfer ] button. Notifications will provide file acquisition progress or error messages. Transferring Files to Williams International After Aircraft flight files have been acquired, transfer to Williams International is available. Change to WI Connection Mode (via Internet) by using the [ Connect to Internet ] or [ Make a Connection ] button on the home page to access the iPad Settings (Wi-Fi) and select the appropriate Internet network. Once the Williams Connect (Internet) Wi-Fi setting is selected, return to the MyEngine home page and verify availability via the [ Wi-Fi ] display. File transfer to Williams International will begin automatically. Files can be re-sent, or a cancelled transfer can be restarted, by using the [ Retry Transfer ] button. Notifications will provide file transfer progress or error messages.

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.
