SkyLog-25A
25-Hour CVR Designed for Legacy Recorder Replacement
SkyLog-25A takes a different approach, focusing on the practical challenges of replacing legacy cockpit voice recorders.
Its design allows operators to simplify the upgrade process by retaining existing cockpit control panels and cockpit area microphones in applicable installations, helping minimize aircraft modification and installation work.
A configuration-module approach also allows one recorder part number to support multiple aircraft types, making SkyLog-25A particularly well suited for operators managing mixed fleets.
SkyLog-25A is a strong fit for operators seeking:
- 25-hour cockpit voice recording
- A streamlined legacy CVR replacement
- Minimal aircraft modification
- Simplified installation
- Retention of existing cockpit control panels and microphones where applicable
- A common recorder solution across multiple aircraft types
- Reduced spare inventory and maintenance complexity
- A practical upgrade path for existing aircraft
- No crew training as the SkyLog-25A behaves like the legacy recorder that was removed
