Advanced Flight Data & Cockpit Voice Recorder

SkyLog-25 CVFDR

The flight recorder (SkyLog-25 series) product line meets all EUROCAE ED-112A requirements for all aircraft classes in CVFDR or standalone FDR or CVR requirements, including 25-hour cockpit audio and datalink/CPDLC.

Standard digital recording interfaces include:

ARINC717 (auto rate detection up to 2,048 wps)
ARINC429 (4 channels, automatic rate)
ARINC825 (single channel)
RS422/485 (single channel)
10/100 Ethernet (3 ports) (e.g. for video recording)

No specialist GSE tools are required for download with an internal web server and standard modular ethernet jack able to connect to a standard portable computer. A restricted-access custom aircraft interface cable can be used to support download of CVR audio data without need for removal from the aircraft and subsequent recertification. A standard Internal TPM 2.0 security chip also enhances cyber security when connected to other ethernet based aircraft systems.

The unit incorporates dual redundant 28VDC power inputs as well as internal Recorder Independent Power Supply (RIPS) as standard to support 10-minute backup.
