SENTRY Smallest. Simplest. Retrofit-ready. An ED-112A certified CVR, FDR or CVFDR built to go into the aircraft you already have, without asking for structure, wiring or panel space you do not have to give. Legacy recorders are getting harder to source, harder to support and harder to keep compliant. SENTRY replaces them in the same location, using an adapter tray where the bay was sized for a larger unit, so a recorder change stays a recorder change instead of becoming a structural modification. The smallest and lightest by design Fits the fleet you actually operate An FPGA-based architecture in a titanium enclosure, under 5 lb. Reduced footprint and low mass support direct replacement of legacy recorders without introducing new aircraft constraints. Ethernet, ARINC 717 and 429 with auto-detection, RS422/485, analog and discrete inputs, rotor speed and four audio channels. Where aircraft outputs do not match, an FDS MAU formats the data upstream. Modernized memory protection Optional integrated RIPS A patent-pending memory protection system designed to stay reliable under extreme conditions, without depending on aging components or proprietary legacy designs. Up to 10 minutes of recording continuity after power loss, which is usually where the most useful part of an event sits. The United States, Canada and Mexico now require 25-hour cockpit voice recording, and the requirement continues to spread. Most fleets will meet it during scheduled maintenance rather than through a dedicated program, which makes recorder envelope and wiring impact the deciding factors. SENTRY25 keeps the SENTRY enclosure, interfaces and ED-112A certification basis. A service bulletin upgrade is available to current and new SENTRY customers. Orders are being accepted now, certification is scheduled for completion in October 2026, and shipments begin January 2027. CONFIGURATIONS 2-hour and 25-hour CVR and CVFDR, and FDR. CERTIFICATION ED-112A certified, DO-160G qualified. Installation approvals are published in the Flight Data Systems STC library. LIFECYCLE Works with HHMPI and Flight Data Systems readout services, so the recorder, the download tool and the compliance report come from one source.
