Hillier will take up his new role from 1 August when he replaces Dame Deirdre Hutton who has held the position for the past 11 years.

Transport secretary Grant Shapps selected Hillier, who was head of the RAF from 2016 to 2019, for the CAA position following an open competition.

Grant Shapps said: “This is an extremely challenging time for the aviation industry, unlike anything we have faced, so the need for an inspiring and experienced leader is vital.

“I’m confident he will excel addressing the challenges presented by Covid-19. I am also excited to work with him and support the CAA’s new vision once the industry is back on its feet.”

One of Hillier’s main tasks will be preparing the CAA to take over the UK’s aviation safety responsibilities from the European Aviation Safety Agency (Easa) following Brexit.

“I am delighted to have been given the opportunity to help lead the CAA through the enormous challenges which lie ahead,” added Hillier.

Hutton called her 11 years at the CAA “an extraordinary period starting with the closure of pan-European airspace due to the Icelandic volcano and ending with the current challenges of Covid-19”.

“The organisation has changed immeasurably, and I am proud of the way we have revolutionised our approach to safety regulation, launched a world leading innovation hub and put consumers at the heart of what we do,” she added.
