LINCOLN, NEB. — Duncan Aviation is pleased to offer its Pilatus PC-12 customers the new Archangel Attitude & Heading Reference System (AHRS), which is designed specifically to replace the obsolete LITEF LCR-92/93 AHRS. As Pilatus owner/operators know, the LCR-92/93 delivered dependable service for decades. However, as these units age, support has become limited, repair costs are rising, and turnaround times are increasing, necessitating longer downtimes, while the available upgrade paths can require significant investment.

Duncan Aviation supported Archangel’s certification efforts as it worked through the installation and integration of the new system. The FAA recently approved the Archangel AHRS, and Duncan Aviation can install it in all of its main MRO facilities and all of its Satellite avionics shops. Because of the straightforward nature of the installation and its use of existing architecture, our techs can even come to your hangar to install this new AHRS. Duncan Aviation can complete most installations in less than a week, making fairly quick return-to-service.

“It’s been a pleasure working with Duncan Aviation during the development of this certification project and the initial installation at the Duncan Aviation Dallas Satellite facility. They have been thorough and professional, and we’ve relied on their avionics and engineering expertise as we developed the Supplemental Type Certificate (STC) for our new Attitude & Heading Reference System (AHRS),” said VP of Business Development at Archangel Systems Aria Bahawdory. “We are confident that our new AHRS will provide Pilatus owner/operators with a practical, dependable, affordable system to replace their obsolete inertial sensing systems.”

The Archangel Systems’ solid-state AHRS unit replaces the LITEF LCR-92/93 with current-generation inertial sensing technology that preserves compatibility with the aircraft’s existing avionics architecture. The upgrade incorporates Archangel’s AHR75 and AHR150A inertial sensing systems, magnetic sensing units, and digital-to-analog converters, and it includes a dedicated installation kit with adapter harnesses and mounting hardware.

Even more practical, the new Archangel adapter plates fit the existing LCR-92/93 mounting locations, while adapter harnesses allow the new system to connect to the existing aircraft wiring without requiring any modifications to the original wiring, which avoids extensive and expensive structural modifications to the flight deck or aircraft. This fully certified new system weighs roughly the same as the LCR-92/93, requires no periodic maintenance, and provide comparable accuracy as demonstrated during extensive flight testing. The components are TSO-approved and incorporate Level A software. The AHR150A also incorporates a Reduced Vertical Separation Minimum (RVSM) capable air data system that supports potential future avionics upgrades.

Paul Cremer

My name is Paul Cremer, and this marks my 42nd year working within the business and general aviation industry. Over this time, I’ve had the privilege of overseeing a diverse array of sector activities, ranging from aircraft charter and management to air ambulance services, ground operations, air traffic control, airport management, technology implementation, and the outsourcing services I currently manage.

In my role focused on delivering advisory, technology, and outsourcing services to aviation customers, I handle a wide spectrum of responsibilities. This includes overseeing International Trip Support, Operations Control Centre Services (OCC), Continuing Airworthiness Management Service (CAMO), Airworthiness Reviews, ARC Services, Aircraft Delivery and Re-delivery Support Services, Maintenance Coordination Services including AOG, Tech Ops (Maintenance Control Centre), and managing myairops software products. As the Head of Aviation Delivery, I lead the customer-facing delivery of Technology & Outsourcing products and services for the market, drawing upon a wealth of knowledge, expertise, and industry connections within Gama Aviation’s Technology and Outsourcing Strategic Business Unit.

My journey into Business and General Aviation began during my teenage years while still in school. I was fortunate enough to be welcomed into the industry, starting at a flying club, and later working at the Air Traffic Services Unit at Blackbushe Airport. There, I maintained the ATC Movement Logs in the Control Tower during weekends, solidifying my passion for aviation. Upon completing my schooling, I seized opportunities at Fairoaks Airport, where I began as Ground Crew while pursuing my Aerodrome Flight Information Service Officer’s license. Advancements in my career led me to the role of Air Traffic Services Manager.

Since joining Gama Aviation in 1996, I’ve held various positions, including Operations Manager (Post Holder), Operations & Commercial Manager, Commercial Manager, Operations Delivery Manager, Head of Business Aviation Delivery, and currently, Head of Aviation Delivery. This role encompasses Gama Aviation Group’s Gama Aviation, myairops, and FlyerTech companies.

In 2023, I was honoured to be invited to serve as the Chair of the Operations Working Group for the British Business & General Aviation Association. This opportunity allows me to contribute to industry initiatives within BBGA’s membership of nearly 200 industry companies, focusing on challenges such as regulatory compliance, Air Services Agreements, technological advancements, workforce development, operational matters, and sustainability.

Marc Bailey

Marc Bailey has spent his career in aviation and has worked in most areas of our industry with scheduled airlines, MRO’s, military contract support and latterly with associations, government, and its agencies.

Marc currently represents your position in Europe (even post Brexit) – as President of ECOGAS (European Council of General Aviation Support) which maintains a voice with EASA. All the major member states are represented on the ECOGAS board. With EASA restructuring its meetings with industry, ECOGAS is now well positioned to represent our position in all areas following industry partnerships with the European Continued Airworthiness Group and with the Association for Remotely Piloted Aviation Services (ARPAS). 

Marc is chair of the UKASF (United Kingdom Airworthiness Strategic Forum) as part of an initiative to develop Aviation Services across all aviation activities.  The UKASF pulls together airlines, MROs, Rotary, Drones, and commercial GA bodies to work with CAA and DfT. The objective is for industry to take the lead to drive strategic issues to benefit all parties. We are well positioned after six years to continue our good work for industry. With the re-established role of Chief Surveyor in the CAA we have a good focal point to undertake this work with the regulator including regular discussions and a full industry day with the CAA each year.

Marc chairs the CAA Finance and Services Forum, which allows industry in the UK to discuss the financial plans for the CAA and look closely at the services being delivered to industry. This is a new and valuable new platform for all parties.

Marc has formed an alliance with, ARPAS, AOPA, BHA and BBGA so that we can strengthen our voice under a joint ‘GA 4 Biz’ banner. This alliance is working to do everything possible to represent the industry’s business interests with UK government and to help realise the Government’s desire to make UK General Aviation a Global Leader in a post Brexit environment. 

The next Generation initiatives with industry and government have continued to develop with the retention platform now evolving into the “Aviation Skills Recruitment Platform” .  The platform now not only offers a vehicle for those offering and seeking posts in aviation, it also provides pathways with its TalentView portion seeking to provide pathways for new entrants into our sector. 

The recruitment platform is being further developed to include training opportunities across a wide range of providers, from government agencies through academic bodies. Getting our next generation activities right in the UK over the next couple of years is our single most important issue which we in aviation must grab with both hands. Moving into 2026 we are seeking to further develop the pathways to enter aviation, and this effort is being supported with development of multimedia platforms with the organisation Metaverse. This multimedia approach is being developed so that it is more relatable to the next generation of people wishing to join aviation in a myriad of roles.

In the role of President (honorary) Marc can support the BBGA in many aspects and continue to ensure that we retain the right connections across industry, with regulators in the UK, regulators in the EU and wherever possible help hold government and its departments to account using normal channels, and where necessary utilise All Party-Political Groups for aviation.
