A Miami-bound Scandinavian Airways flight was compelled to return to Europe on Thursday (November 14) after experiencing excessive turbulence over Greenland.
The aircraft took off from Stockholm, Sweden, at midday on Thursday and was scheduled to land in Miami at 5.45 pm native time. Carrying 254 passengers, the plane landed after 11 pm in Copenhagen, Denmark, after over 10 hours within the air.

Based on CNN, no extreme accidents have been reported amongst passengers or crew on flight SK957. In an official assertion, the airline mentioned that passengers have been met by a “particular help workforce” upon arrival in Copenhagen the place they have been “assisted with rebooking”.
Based on the airline, the choice to return to Europe was based mostly on the Miami Worldwide Airport missing enough services to conduct an inspection on the trigger. Notably, incidents of extreme turbulence are additionally turning into more and more frequent on account of local weather change. Right here is why turbulence occurs and passengers ought to be mindful when confronted with such a state of affairs.
What occurs when an plane encounters turbulence?
As a naked idea, turbulence means disruption of airflow over the wings of an aeroplane, which causes it to enter an irregular vertical movement. There are at the least seven totally different sorts of turbulence that an plane can face:
WIND SHEAR: Happens when there’s a sudden change in wind path, whether or not vertically or horizontally. Sometimes happens near thunderstorms, jet streams, and so on.; tough for pilots as tailwinds instantly change to headwinds or vice versa.
FRONTAL: Created within the frontal zone when heat air is lifted by a sloping frontal floor and friction between opposing air lots. Most palpable when heat air is moist; depth will increase with thunderstorms. Mostly near thunderstorms.
CONVECTIVE: When land floor temperature rises, the air above the bottom heats up and rises, creating air pockets round it. Convection currents trigger difficulties throughout strategy as they have an inclination to have an effect on the speed of descent.
WAKE: Kinds behind an plane when it flies by air-creating wingtip vortices. These might be harmful for small plane following larger ones, which are inclined to disrupt the airflow extra strongly of their wake.
MECHANICAL: This sort of turbulence happens when tall strong objects comparable to mountains or highrise constructions disrupt the traditional airflow, inflicting the air for planes to fly by to change into soiled.
CLEAR AIR: Happens when an plane crosses from one air mass to a different, which has a distinct path. Clear air turbulence might additionally occur when an plane strikes out of a jet stream. Clear air turbulence is principally brought on by wind or jet streams.
MOUNTAIN WAVE: Probably the most extreme; these are oscillations that kind on the downwind aspect of mountains when robust winds circulate in direction of mountains in a perpendicular vogue. Plane monitoring perpendicularly throughout, or downwind of a mountain, might expertise a sudden lack of altitude adopted by a sudden discount in airspeed.
Are all turbulence incidents harmful?
It relies on the character and depth of the turbulence. Plane face some type of turbulence regularly, and pilots are skilled to take care of these disturbances.
Nevertheless, there have been a number of cases of turbulence bringing down fashionable jetliners. However in these instances, whereas intense turbulence has been the principle explanation for an accident, a number of different contributory components — comparable to lack of correct coaching, poor dissemination of weather- or wind-related data — have contributed to the accident.
What should passengers do when an plane encounters turbulence?
Based on the US Federal Aviation Administration (FAA), “passengers can easiley stop accidents from surprising turbulence by protecting their seat belt buckled always”.
It suggests passengers hearken to directions from flight eattendants; take note of the protection briefing at the start of the flight; put on a seat belt always; use an permitted youngster security seat or gadget if a toddler is below two; and cling to carry-on restrictions.
How can airways keep away from turbulence?
The FAA recommends that carriers enhance dispatch procedures by protecting communication channels open full-time; embrace turbulence in climate briefings; promote real-time data sharing between pilot and dispatcher; reinforce the provider’s turbulence avoidance coverage by dispatcher coaching; think about rerouting utilizing atmospheric modelling, and information shows; and use all relevant climate information.
It additionally suggests utilizing working procedures and coaching to stop turbulence accidents, emphasising the significance of flight attendant’s private security, selling communication and coordination, and gathering information and reviewing the air provider’s historical past of turbulence encounters and accidents.
That is an up to date model of an explainer revealed in 2021.
