Allied Signal UFDR 980-4100

If you plan to manage and take control of your FDR compliance program (download, readout, and calibration), you will benefit from the use of our diverse family of FDR support products. Our reliable interface solutions are designed for “ease-of-use” and require minimum training.  

Downloading your FDR on wing reduces spares costs and minimizes damage to your unit during shipping. Using our FDR download unit (DOWNLOAD process), Flight Data Analysis software (READOUT process), and ARINC 717 DSDU (CALIBRATION process), you can easily satisfy your local regulatory requirements for surveillance of FDR data. In addition, by using our products to troubleshoot and monitor exceedances in your fleet, you will quickly receive a return on your investment.

The first step in FDR maintenance is extracting the FDR stored data in order to perform the necessary FDR READOUT. The data – binary file – is then converted to engineering units and graphical format using READOUT software. After reviewing the FDR data and identifying parameters which fall outside of mandated range, resolution, and accuracy limits, CALIBRATION may be required in order to legally return the aircraft to service. This 3 part process is essential for the continued airworthiness of your Flight Data Recorder System (FDRS).
