These 12 errors by Shoreham Airshow pilot Andy Hill show he was cognitively impaired, expert says

Aviation safety expert Dr Stephen Jarvis told the Old Bailey today that Hill made up to 12 errors in just 23 seconds.

When asked what caused these errors, Mr Jarvis said the only explanation that satisfies him was that Hill suffered a form of cognitive impairment.

Hill, 54, of Standon Road, Buntingford, is standing trial charged with 11 counts of manslaughter by gross negligence. He denies the offices.

He was flying a vintage Hawker Hunter jet at the airshow in 2015 when it crashed onto the A27, leading to the deaths of 11 men.

This morning the trial heard from another expert who said there was 'no indication' that Hill had lost consciousness during the flight, despite his claim to a paramedic.

'Cascade of errors' towards the end of Andy Hill's display

Dr Jarvis said the was a 'cascade of errors' towards the end of Hill's flight in the Hunter.

He added: "At that part of the flight errors start to be made and quite a lot of them."

Dr Jarvis says Hill's decision to cut the RPM of the aircraft was 'odd'.

"It is the last thing you would expect a pilot to do at this point."

Up to 12 errors made in quick succession, expert says

Dr Jarvis told the court: "What we have got here is a whole set of errors all moving towards the tragedy.

"I would say it is definitely seven or eight, possibly rising to 12, all in a 22-23 second period.

"[It] is more remarkable to make that many errors in that short space of time."

Looking at Dr Jarvis' witness statement, defence barrister Karim Khalil QC read out the list of 12 errors he believes Andy Hill made:

1. "Power reduction after point X [in the flight]

2. "Continuing to turn beyond that inbound track

3. "Failure to notice or act upon the low airspeed

4. "Pitch oscillations

5. "Entering the manoeuvre too early, away from the crowd

6. "Inappropriate pull up [into the loop]
