CVR flight data recorder SferiRec

for aircraft

Overview
The aviation sector requires precise information to determine causes of accidents and incidents, which may stem from human factors, communication breakdowns or unforeseen events. Cockpit voice recorders (CVRs) and data link recorders (DLRs) capture critical cockpit audio and data to support investigations, safety analysis and training.

Our solution
The SferiRec CVR by HENSOLDT is a combined cockpit voice recorder and data link recorder with a modular architecture. It stores CVR audio and DLR data on an integrated crash‑protected memory module (CPM) using solid‑state memory technology. At only 3 kg (6.61 lbs), the SferiRec CVR is among the lightest ED‑112A units available.

Features

• Certification: ED‑112A, EASA ETSO‑2C123c and ARINC 757
• Weight: 3 kg (6.61 lbs)
• Supply voltage: 28 VDC or 115 VAC (variable frequencies)
• Underwater locator beacon (ULB) provided as a separate line‑replaceable unit (LRU); universal mounting for different ULB types

Benefits

• Up to 45 hours cockpit voice recording (CVR)
• Up to 170 hours data link recording (30 hours at highest throughput)
• Field‑loadable software and easy read‑out without A/C power
• One of the lightest ED‑112A CVRs on the market, supporting weight‑sensitive installations
