The Cumberbatch Trophy

Awarded for an outstanding contribution to aviation safety.

2025 awarded to:  Mark Greenfield FRAeS

647 - Mark Greenfield CumberbatchMark is recognised throughout the aviation industry as a masterful instructor in UPRT. His reputation is not only built on technical knowledge, but on his outstanding ability to teach. Mark has an instinctive understanding of how people learn under pressure, and his students consistently praise him for making complex flying concepts both accessible and memorable.

What makes Mark exceptional is his ability to translate high-risk, high-stress flying scenarios into simple, practical steps that pilots can understand, recall, and apply—particularly when it matters most. His approach is built on clarity, empathy, and repetition of good habits, helping pilots develop the confidence and muscle memory they need to safely recover from unexpected upsets.

Mark creates a calm, supportive learning environment that allows students to push their limits while feeling safe and in control. He’s widely described as not just an expert instructor, but someone who genuinely connects with his students. Whether teaching nervous cadets or seasoned airline pilots, Mark ensures each session is tailored to individual needs while maintaining the highest standards of safety and professionalism.

His journey to becoming one of the UK's foremost UPRT instructors began with RAF fast jet training. A medical condition paused his flying career, but ten years later, after regaining his Class One medical, Mark returned to aviation with renewed passion—this time with a mission to teach. He played a central role in shaping modern UPRT standards, representing the UK on the EASA Rule Making Group that led to the introduction of mandatory on-aircraft UPRT in 2019.

As the lead UPRT instructor at Ultimate High, Mark has worked with pilots at every level, from ab initio cadets to test pilots and airline training captains. He is especially skilled at guiding students through the critical psychological elements of UPRT—particularly the startle and surprise effects that can undermine decision-making during real-world upsets. His structured, intuitive teaching focuses on situational awareness, resilience, and timely, effective control inputs.

Under his leadership, Ultimate High has become a centre of instructional excellence in UPRT, trusted by major organisations including Rolls-Royce, Boeing, AirTanker, and the AAIB. Mark’s training isn’t just effective—it’s transformational, consistently leaving pilots better prepared and more confident.

Beyond the cockpit, Mark actively shares his knowledge across the aviation community. He regularly presents at major conferences such as EATS, speaks at safety seminars, and contributes thought-leadership articles to industry publications. His advice is sought by regulatory bodies including CASA (Australia) and the Kenyan CAA. Through webinars, livestreams, and public writing, Mark continues to improve how UPRT is understood and delivered across the industry.

Students and peers speak with admiration, describing him as “an exceptional instructor” who combines technical brilliance with real human connection. His training is frequently called “vital,” “practical,” and “inspiring.”

Mark has not only set a benchmark for instructional excellence in UPRT—he’s helped redefine what world-class flight instruction looks like. His impact on pilot safety, confidence, and skill is lasting and profound.  He is a very deserving recipient of the Cumberbatch Trophy.
