The dangerous seating position you should always avoid on a flight in case of turbulence

: “Dispersing your weight between your pelvis and feet can take the pressure off your back and make it easier to stay upright for longer.

He added: ";If you happen to already be standing when turbulence hits, immediately sit down on the floor where you are and hold onto a nearby armrest."

Kyle Koukol, a commercial pilot, has also advised nervous flyers to take a seat in the middle of the plane near the wings to be closer to the centre of gravity.

It comes after another expert revealed the best seats to pick if you want to increase your chances of sleeping.

Gabby Beckford, the founder of travel site Packs Light, told HuffPost: “No one likes the middle seat for obvious reasons, and the window allows me to entertain myself and a better opportunity to sleep.”

When sitting by the window, you are less likely to be disturbed by other passengers getting up to use a toilet.

You can also use the window as a support to lean on when space is already tight in the planes.

Passengers have also been encouraged to carry out a number of pre-flight checks to ensure you can find the best seat on a flight.

Last month, a Singapore Airlines flight from London hit extreme turbulence.

There were multiple injures onboard flight SQ321 to Singapore, and the death of a 73-year-old British granddad.

Shocking pictures taken onboard showed people slumped in chairs with smashed noses and bloody faces, with ceilings ripped apart and dents in overhead lockers where bodies had slammed into them.

Unfinished meals were seen strewn across the galley kitchen of the plane, along with kettles, rubbish, and bottles of wine.

Geoff Kitchen, 73, died of a heart attack after the Boeing jet plunged 7,000ft in just six minutes sparking mid-air panic.

Andrew Davies told BBC Radio 5 Live there was "very little warning", adding "the seatbelt sign came on, I put on my seatbelt straight away then the plane just dropped".

He said: "Lesson is - wear a seatbelt at all times. Anyone who is injured was not wearing a seatbelt. People who kept them on (including me) are not (as far as I could tell)."

Mr Davies added the plane "suddenly dropped" with "very little warning".

He said: "The thing I remember the most is seeing objects and things flying through the air.

"I was covered in coffee. It was incredibly severe turbulence.

"During the few seconds of the plane dropping there was an awful screaming and what sounded like a thud."

Mr Davies added that when the seat belt sign came on, he followed the instruction, and "at that very moment, the plane suddenly dropped".
