I congratulate the hon. Member for Arfon on securing this debate and appreciate his advocacy for his constituents. The Royal Air Force remains vital to national security, requiring rigorous training that includes essential low-level flying. Since 2012, there have been seven aircrew fatalities; efforts are made to ensure pilots are well-trained while recognising the impact of noise pollution. RAF Valley is a significant employer and contributor to Ynys Môn with £3.5 billion in investment for military training. The minister acknowledges increased complaints about low-flying in 2020, noting that 95% of night flying occurs before 10pm. Efforts are made to spread flight activities equitably across Wales, the Isle of Man, and Cumbria to minimise localised noise impact. The minister discusses safety improvements for Texan aircraft operating over water, highlighting that while automatic features for life preservers have been resolved, an automatic deployment feature remains under development. He commits to further investigation into spreading flights beyond north Wales and addressing public concerns through the MOD's low flying complaints unit. Noise levels from military aircraft are generally decreasing over time, but improvements may be limited by technical constraints.
