3 EQUIPMENT QUALIFICATION
3.1 TSO
The TXA201 triaxial accelerometer meets TSO-C124c requirements and is intended to
provide data to a flight data recorder (FDR) at a rate and accuracy that is compatible
with the FDR.
3.2 Application
The TXA201 is designed to provide accelerometer inputs for digital flight data recording
equipment.
3.3 Environmental
The accelerometer is environmentally qualified for aircraft applications per RTCA DO-
160G testing as shown in Table 3. The environmental qualification categories shown
support typical installations in Part 25 aircraft models.
