Leading Through

Quadrant Group comprises Quadrant Systems Limited (QSL), the UK operating company based in Burgess Hill, West Sussex; Quadrant Simulation Systems, Inc. (QSSI), the US operating company based in Orlando, Florida; Micro Nav Limited, the ATC simulator specialist operating in Bournemouth, Dorset; and Quest Flight Training Limited (Quest), based at RAF Waddington, Lincolnshire, UK.

QSL provides a comprehensive range of services that cover all of the core areas of flight simulation tailored to the specific needs of both civil and military customers in the UK and worldwide.

QSSI provides a comprehensive range of services that covers relocations, manufacturing services, visual systems updates and OEM support.

Micro Nav is a leading specialist company developing and supplying Air Traffic Control (ATC) and Air Defence simulators and training systems.

Quest is a 50/50 joint-venture with Rockwell Collins to deliver the Sentry Aircrew Training Service to the UK Ministry of Defence; the Service is delivered by Quadrant.

All Quadrant activities are performed under the auspices of our ISO 9001:2008 Approved Quality Standards which are regularly audited by LRQA (Lloyd's Register Quality Assurance).

Focus at all times is on delivering high quality solutions that meet customer requirements on time. The comprehensive range of products and services, covering all key areas, is tailored to suit individual needs for both Military and Civil customers worldwide.

Quadrant is an aviation simulation and training business founded in 1994 by current CEO, Jeff Sandiford and Chairman, David Coghlan. Jeff’s career prior to Quadrant included being managing director of two of the then largest flight simulation companies in the world, Rediffusion Simulation and Singer Link-Miles. David is an investor and chairman/director of a number of small-to-medium sized technology companies, public and private, including the chairmanship of Synectics plc.

The Company quickly built a reputation for offering a professional, quality service and in 2000 Quadrant won a prestigious, 25 year MoD contract valued at over £60m. Quest Flight Training (Quest) was set up as a special purpose vehicle on this project to provide the E-3D Sentry Aircrew Training Service (SATS) at RAF Waddington for the UK Ministry of Defence. This is a 50/50 joint venture with Rockwell Collins with Quest being operated by Quadrant.

The Company continued to grow and build on its reputation for quality, leading to Quadrant being selected by Merlin in 2003, to maintain and support 4 Tucano Simulators and 6 Tucano Cockpit Procedure Trainers at RAF Linton-on-Ouse. This programme has been running successfully and will potentially continue until 2020.

The next milestone for the Group was the start up in Orlando, Florida, a strategic move to establish a US presence which opened up opportunities with the US military and US based prime contractors. Quadrant Simulation Systems, Inc. (QSSI) has become a clear global leader for simulator relocations. Subsequently there has been growth in manufacturing services and visual systems support.

Another key event occurred in 2012 with the acquisition of Micro Nav Limited.  Unlike the other companies, where the main area of business is flight simulator based, Micro Nav introduces another core competency, that of ‘Air Traffic Control Simulation and Training’, in which it is a world leader.

The operating companies that now form the Group are: 

  • Quadrant Systems Ltd. – Burgess Hill, West Sussex, UK
  • Quest Flight Training Ltd. – RAF Waddington, Lincolnshire, UK
  • Quadrant Simulation Systems, Inc. – Orlando, Florida, USA

In July 1994 David Coghlan and Jeff Sandiford founded Quadrant Systems, which has now been in the Aviation Training & Simulation Business for 25 years.

Quadrant started with the acquisition of certain assets from Ceselsa of Spain (now INDRA) in their subsidiary ASDL based in Burgess Hill, West Sussex, UK. This included acquiring B727 and B747 Flight Simulators and taking on the Building Lease and 16 skilled Employees.

The Business developed over the early years with Simulator Dry Hire, Relocations, Updates and Manufacturing Services.  Today there are 4 Flight Simulators operational at Burgess Hill, 2 of which are used for both Dry and Wet Training and 2 of which are on Housing & Maintenance Contracts.

In 2000 Quadrant had a major breakthrough with the award by the UK Ministry of Defence  of the E-3D AWACS PFI aircrew training programme (together with our then partners Evans & Sutherland, now Collins Aerospace).  This is a £60M+ Contract running for 25-30 years. The Training Service, managed by Quadrant, was established at RAF Waddington, Lincolnshire, UK and has been successfully training RAF pilots and other aircrew for over 18 years.

Another key development in 2004 was the start up of Quadrant Simulation Systems, Inc. based in Orlando, Florida, USA.  This Company has progressed to become the undisputed global world leader in Flight Simulator Relocations today and has strong Manufacturing Services and Visual Support Programmes in its portfolio.

The acquisition of Micro Nav Limited based in Bournemouth, Dorset, UK in 2012 enabled Quadrant to diversify into the Air Traffic Control Simulation Business.  Micro Nav is a global leader in its market place with its BEST Product Line of Tower and Radar Simulators plus Air Battle Management Simulators.

Quadrant has also been developing its new INTERACT Simulated Air Traffic Control Environment (SATCE) Product designed to deliver the “missing link” in the Flight Simulator.  Several INTERACT systems have now been integrated with OEM and Customer Simulators for evaluation and the INTERACT Product is expected to play a key role in the future of the Company.

Quadrant has reached £25M in annual Revenues at the 25 year mark.  Charting a pathway through the past 25 years has not been easy as the margin for error in the Training & Simulation Business is quite small.

However plans have been pursued with determination and a strong belief in successful outcomes.

It seems appropriate to pause and reflect at this important milestone and the Board of Directors of Quadrant would very much like to record its thanks and appreciation of the contribution to the Company over the years from all its Stakeholders:-

  • ­          Shareholders who put their faith in the Company
  • ­          Customers who trust the Company with their Business
  • ­          Employees who make it all happen
  • ­          Suppliers and Advisors who support the Company

Events are being held at all locations within the Company to celebrate 25 years in Business.

Quadrant has strong Business Plans in place for the future in all areas of the Company and looks forward to the next stage of growth with confidence.
