Speel’s Fligh data Acquisition Units (FDAU) come in different form factors and capabilities to accommodate various customers needs.  All FDAUs are specifically designed to suitably connect to SPEEL’s FDRs.

The FDAU acquires analog and discrete signals from various transducers onboard the aircraft as well as digital data from aircraft databus (ARINC-429, MIL-STD-1553). These input signals are converted by the FDAU into a digital data stream that it transmitted continuously to SPEEL’s Crash-protected solid-state recorders.
