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
