11 terms found

Autothrottle

Aviation technology

Automatic thrust-control system. Erroneous EPR values caused it to limit thrust while speed decreased until the stall.

CVR

Flight recorders

Cockpit voice recorder. The AH5017 CVR was damaged and contained no usable data.

Official case page Final report

Engine anti-icing

Aviation technology

System intended to prevent ice accumulation in engine air inlets. The report states that these systems were not activated while crossing the cloud area.

Sources:

Official case page Final report

Engine Pt2 pressure sensors

Aviation technology

Sensors measuring total pressure at each engine inlet. According to the final report, they were probably obstructed by ice crystals, producing erroneous EPR values. This was not a Pitot-probe obstruction.

Official case page Final report

EPR (Engine Pressure Ratio)

Aviation technology

Pressure ratio used to set and monitor thrust. Probable obstruction of the Pt2 sensors produced erroneous EPR values and the autothrottle limited thrust.

FDR

Flight recorders

Flight-parameter recorder. The AH5017 FDR was usable and helped reconstruct the technical sequence.
