‘Without fail I would book Clear Sky every time for training.  I have used Clear Sky for several fuel farm and de-icing auditing training courses and the courses are delivered in such a way they are Informal and easy to learn.  Steve has great skill keeping students engaged throughout, and both Steve and Paul are completely knowledgeable and experienced in their field.  Fun, easy to learn, informative and relaxed training!!’

I have been working with Steve since 2014. We were looking for DAQCP inspector at that time, and Steve was exactly the one we needed.

It is a pity that we did not have the chance to use Steve knowledge for 100% (IFQP, Part 145 and etc.) but only in DAQCP. However, I am 100% sure that other areas are also well managed and controlled by him without fail, like he does it in DAQCP. He makes it easy and smooth!

I am very grateful to Steve for his irrefutable experience and skills and all the knowledge and experience he shared with me during our cooperation, which has helped me to achieve certain qualifications and expertise. Steve is always involved in our discussions related to the winter season or de-icing ops issues. And his contribution is obvious.


Air Astana intends to continue working with Steve Crawley, who is ready to share his solid years of experience in de-icing ops and thus helping Air Astana to improve the flight safety programme.

Steve was part of the technical working Group in the Lufthansa-Fuel-Group. It was not only a pleasure working with him but he was always a partner one could rely on. Excellent technical expertise and very focussed when it comes to details. His support very much helped to improve the standards not only within the Lufthansa Group but also when actively pushing the discussions on Industry meetings (IATA)

I have worked, as overall launch project manager, with Steve on a number of projects around route development to complex stations in Africa, the Sub-continent and the Middle East. Steve has efficiently supported every route launch in his responsibility for securing our fuel and de-icing operations and audits over the last five years. I certainly recommend Steve for his ability to support delivery projects.

No job too big" would be how I would describe Steve. No matter what I threw at Steve he carried it out with enthusiasm and energy whether it was in his day to day role or something completely new and outside his comfort zone. He approaches everything a professional attitude and a personable demeanour.

I have worked with Steve over a number of years in various situations and always found him to be knowledgeable of the subject in hand having ensured the details he provided were accurate and valid. His experience within the fuel and De-icing auditing environment has provided excellent guidance in my decision making on how the organisation should approach either subject, both technically and financially.
