Is this finally the end of bumpy flights? Boeing to trial a long-distance LASER that will spot pesky clear-air turbulence up to 10 miles away

  • Boeing will be trialing remote-sensing technology in 2018 on board a 777 
  • A lidar system will warn pilots of clear air turbulence, which has no visual clues
  • It's thought that the system would give crews about 60-seconds warning 

It's probably the most unpleasant part of aviation.

But turbulence may become a thing of the past thanks to new technology that promises to predict the type that lurks unseen - and steer planes around it.

That's according to Boeing, which will be trialing remote-sensing technology that can detect clear-air turbulence early next year.

New era in flying? Boeing will be trialing remote-sensing technology that can detect clear-air turbulence early next year

The concept, which they hope could be rolled-out across all commercial carriers, comes from a seven-tear collaboration with the Japan Aerospace Exploration Agency (JAXA) and has huge potential for travellers.

According to the Federal Aviation Administration, the number of turbulence-related injuries doubled in 2016, from 21 to 44.

But this could be slashed by lidar (light detection and ranging technology), which will work by emitting pulses of laser light from the plane's nose, scattering small dust and other particulates.

Observing the reflected light in segments, the pulse provides measurement of the wind speed at increments all along the direction of the laser.

It offers the potential to accurately measure winds as much as 17.5 kilometers (10.8 miles) in front of airplanes and provide pilots with sufficient time to take appropriate action to avoid wind shear and clear air turbulence, which often occurs at high altitude and does not have any visual cues, such as clouds.

HOW DO PILOTS DEAL WITH TURBULENCE? 

A serving airline captain reveals four methods for dealing with turbulence: 

1. Grin and bear it - the aircraft is more than capable of withstanding the loads associated with turbulence (although severe turbulence can be quite uncomfortable and best avoided for passenger comfort).

2. Try flying higher (if aircraft performance allows it) or lower (although this burns more fuel and might make things worse).

3. Fly at the aircraft turbulence penetration speed - generally a little slower than normal cruising speed

4. Turn to avoid the area of turbulence if it’s localised (such as near a thunderstorm).

These anomalies will trigger audio cues, which will be broadcast to pilots and cabin crew. Experts believe it would provide at least a 60-second heads-up.

However, a Dreamliner pilot told MailOnline that the technology wasn't much more than a toy.

He said: 'Sixty seconds notice? And then what do the pilots do?

'They can't climb or descend as staying level is what gives them separation from other aircraft. And "going round it" with a turn? Most turbulence areas are many miles long.

'It sounds like an interesting toy, but the end of turbulence... no way!'  

The lidar research will be conducted in 2018 as part of a collaboration with FedEx Express.

Over a six-week period more than 30 technologies, including lidar, will be tested on board a new FedEx-owned 777 freighter.  

'We're eager to continue working with JAXA so that we can both learn more about lidar technology,' said Boeing's Doug Christensen, who's overseeing the collaboration. 

When turbulence is at its most severe, it can stall an aircraft, by pushing it below its minimum speed, despite the engines being on full power.

When this is about to happen pilots receive an attention-getter called a 'stick shaker'.   

Speaking anonymously to MailOnline, an airline captain recounted an occasion when he received this warning while flying over north Africa in a 747.

He explained that he came out of the stall by pointing the plane downwards.

'You push the nose forward, keep the power on, let the aircraft accelerate. Aircraft like flying, they don't like falling out of the sky, and you've got to try pretty hard to make them do that,' he said. 

'So, just push the nose forward, accelerate the aeroplane, and we return to our assigned altitude.

'For two to three minutes it was exciting, it was proper flying, the autopilot wasn't coping very well with it, so you take the autopilot out with a little push button on the control column and you go back to basic flying skills that keep the aircraft safe. That's why we're there. 

'That's why there's always two of us on the flight deck and why we take the business of flight safety very seriously. And part of that is putting the seatbelt signs on.'

He added: 'Because we have a lot of people now who fly an awful lot, sometimes they're a bit casual about whether they should return to their seats and put their seatbelts on, and people think it's a bit of a drag, but there will be that one time in a hundred when it suddenly becomes really important to be in your seat.'  

REVEALED: HOW SITTING IN THE FLIGHT DECK CURED ONE MAN'S TURBULENCE FEAR

Our anonymous airline captain reveals how he cured one passenger's fear of flying by inviting him into the cockpit, pre-9/11, during turbulence.

'So, some years ago now, I did a flight back from Bucharest, and it was just one of those days when it was going to be bumpy the whole way. And we got about an hour into it and the purser came up to me and said "I know there's probably nothing you can do about it, but there's a gentleman sat in business and he's asked me to ask you please make it stop, because he can't take it any more".

'And I said we've tried different levels, we've tried going up, we've tried going down, it's just one of those days it's going to be like that. And this was pre-9/11, so we could get people in and out of the flight deck and I actually went back and saw him. And he was a really charming guy, but obviously absolutely terrified. Every time the aircraft bucked and weaved he tensed.

'So I said "why don't you come in? Come and sit with us. If you're going to be scared, you might as well be scared with us, rather than sat here on your own".

'And he told me this story... he was a business guy who had a furniture business. He built furniture in Bucharest, so once a month, he had to go to Bucharest. And for the week before, he'd be terrified, and for the week he was in Bucharest he knew he had to come back and then he'd live two weeks of normal life. And then he'd go back to another week of being terrified. It was just awful.

'So anyway, we kept him in. He was asking if it would fall, and we'd say "no". I took the autopilot out and said: "Look, it'll fly itself. It's just going to sit here. This is where it wants to be. It's at 35,000 feet doing mach 0.76. This is what a 737 wants to do. We're not flying it. It's just here. It's a happy aeroplane." 

'We kept him in for the approach and landing to Gatwick and showed him all the protocols, how we slow down, what we do, how we keep it safe, what we're looking at and so on.

'We got on the ground and he was nearly hysterical with happiness and I thought he was going to cry. He said: "You've have changed the way that I feel about this and I'm going to be better now."

'This was going back about 15 years and I still remember his face and I still remember that flight, the whole hour and a half we had with him in the flight deck and how buzzed he was afterwards. It had set his phobia free.

'And that's one of the real shames about why we can't have people in the flight deck anymore. For very good reason. It's a shame because it makes such a difference to people.

'It's a bit like aversion therapy. You need to have it pushed harder to cure it.'
