"I have worked with Helios on a number of occasions and value their knowledge of the latest developments in ATM R&D and GA impacts in particular. Helios produce quality deliverables on time and to budget, and bring impartiality and appreciation for the multiple air traffic issues impacting the GA community. I have always found Helios to be reliable when working together they have a range of expertise and in recent years they have developed a good understanding of GA across all it's activities."

"All Helios employees that participated on the project were excellent. Understood needs of the project and delivered consistently excellent results. Very satisfied with the work carried out and would definitely consider working with Helios again."

"The Helios team had an excellent understanding of the issues, provided high quality deliverables and respected the deadlines. The Helios project manager demonstrated professional calm, responsiveness and flexibility."

"Since the start of the project, Helios has been the overall coordinator for the supplier side. This has meant dealing with all of the complex project management related issues associated with a large international consortium attempting a novel, complex, technical development. We are very happy with the performance of the team."

"Helios has brought deep knowledge of the ATM industry and market and a broad understanding of the strategic issues which has enabled them to engage with the commercial aspects of our work. They have enhanced our offering to the MoD and have been good to work with."

"The project was managed well from start to finish. The requirements were fully explored and how these could be met was discussed openly with various options explored. Having set out what would be done and by when the work proceeded according to plan and was delivered on time. It met both our expectations and requirements and I would have no problem recommending them for future work."
