Regulatory compliance

Certified to FAA TSO-C123a/b standards and hold EASA ETSO approvals. They meet EUROCAE ED-56A and ED-112 performance requirements, align with ARINC 757 characteristics, and are manufactured under established aerospace quality management systems, providing recognised compliance and technical credibility.

Fleet compatibility

Designed for broad fleet applicability and, when paired with approved installations, can fit many general aviation and transport platforms thanks to Supplemental Type Certificates for specific aircraft. They’re compatible with Acron Aviation CVRs and widely used in retrofit environments, with installers confirming suitability case-by-case against aircraft type certificates and STC data during certification planning.

Operators planning a retrofit or new installation can work with an authorised Acron Aviation avionics dealer to confirm aircraft compatibility and coordinate certification under the relevant STC.

CVRCU solutions

Available in multiple configurations to support varying cockpit layouts, installation requirements, and operational needs, ensuring flexible integration across diverse aircraft platforms and mission profiles.

S161

The S161 variant is designed for aircraft operators seeking a reliable, proven control interface for cockpit voice recorders, especially in retrofit programmes or fleets with mixed legacy and modern CVRs. It’s ideal for commercial, regional, and business aviation operators who prioritise dependable performance and regulatory compliance.

The S161 provides essential control functions including test, erase, and audio monitoring, enabling crews to verify CVR operation and maintain compliance with FAA and EASA standards. Its interface with an external cockpit area microphone ensures high-quality audio capture while supporting legacy aircraft systems.

Built to ARINC 757 form-factor standards, the S161 simplifies installation and integration, minimising downtime during upgrades or retrofits. Its proven design balances operational efficiency with long-term reliability, offering operators a trusted solution for voice recording management.

Key features

• CVR test and erase controls - simple pushbutton operation for system verification and bulk erasure.
• Audio monitor output - headphone interface for real-time audio monitoring.
• External microphone interface - compatible with remote cockpit area microphones. 
• ARINC 757 form-factor compliance - supports standard installation architectures.
• FAA TSO and EUROCAE compliance - meets international regulatory requirements.

The S161 is commonly installed on civil and business aircraft, including regional jets like the Embraer Legacy 600/650, with installation validated through STC or certified retrofit procedures.

S162

Designed for operators who want an integrated microphone CVR control solution that streamlines installation and reduces external wiring requirements. It’s well-suited for civil, business, and retrofit aircraft where simplicity and proven compatibility with legacy systems are priorities.

Combines core cockpit voice recorder control functions - such as test, erase, and audio monitoring - with a built‑in electret condenser microphone, eliminating the need for a separate external microphone. Its compliance with FAA TSO and EUROCAE/ED standards and ARINC form‑factor makes it dependable and easy to integrate with Acron Aviation and legacy CVRs.

Key features

• Built‑in microphone - integrated electret condenser mic simplifies installation and improves audio quality.
• CVR test & erase controls - intuitive front‑panel switches for operation verification and bulk erase functions.
• Audio monitor jack - headset interface for real‑time audio checks.
• ARINC 757 form‑factor - standard panel footprint for easier retrofit projects.
• FAA & EUROCAE compliance - meets relevant regulatory and environmental standards.

The S162 is used across a range of aircraft types that require a built-in microphone CVR control interface, including platforms from Bombardier, Embraer, Honda Aircraft, and Textron Aviation, with suitability verified through installation planning and certification processes.

S261

Designed for operators who need the core functionality of a Cockpit Voice Recorder Control Unit in a reduced‑height, slim form factor. It’s ideal for retrofit programs, space‑constrained panels, and fleets that prioritize established ARINC‑compliant integration with legacy and contemporary recorders.

The S261 delivers the same dependable CVR control capabilities as the S161 - test, erase, and audio monitoring - while occupying less panel space. It supports standard external cockpit area microphones and interfaces seamlessly with Acron Aviation and legacy CVRs, maintaining regulatory compliance and familiar operation for crews and maintainers. Its slim design simplifies installation where height constraints are a factor.

Key features

• Reduced‑height form factor - slimline footprint eases installation in limited panel space.
• CVR test & erase controls - intuitive switches for system checks and memory clearing.
• Audio monitor output - headset jack for real‑time verification.
• External microphone interface - designed for remote cockpit area microphones.
• ARINC 757 form‑factor compliance - supports standard aircraft installation protocols.

Used across civil and business aircraft installations where a compact CVR control interface is required, the S261 is suitable for retrofit STCs and panel upgrades, meeting operational needs without sacrificing proven integration and performance.
