There is also turbulence caused by mountains or tall buildings that distort the wind flow in the sky or wake turbulence
caused by the airplane's wings, a reason why planes do not take off or land right before and after one another.
Developed within the framework of the Single European Sky ATM Research (SESAR), the 'Wake turbulence
separation optimisation' project involved installing so-called plate lines--which look like a series of walls lined up in the same direction of the runway-in the landing area, which are designed to accelerate wake turbulence
A report by civil aviation authority also found that there was an ATC inconsistency in advising the DA62 of the expected occurrence of hazards caused by wake turbulence

Spatial disorientation in IMC is as different from a moose stall as wake turbulence
is from sloppily flown S-turns on final.
These distances have been defined for the worst weather conditions, which are low wind speed and/or low turbulence intensities that can result in the longest-lasting wake turbulence
, to avoid the risks for a follower aircraft to encounter the wake turbulence
from the leader aircraft.
Caution wake turbulence
." I expected he'd use good judgment and pass behind the descending airliner.
Though even nine miles apart seems far enough to avoid any chance of collision, the minimum legal distances of ten miles and 1,000 feet are chosen not only because of the primary factor of a possible collision, but also the effects of secondary factors such as sudden changes in the weather conditions and wake turbulence
, the disturbance which forms as an aircraft passes through the air.
In a keynote speech at the conference in National Harbor, Md., on November 2, Department of Transportation (DOT) Secretary Anthony Foxx said the DOT estimates that NextGen has already produced nearly $2 billion in benefits through improvements such as recategorizing wake turbulence
separations and implementing satellite-based arrival and departure procedures.
The call sign "heavy" set off an immediate alarm in my head to be cautious about wake turbulence
. It appeared to me, although we did not speak to it directly in the cockpit, that my IP and Aircraft Commander were aware of the situation.
Speakers also gave presentations on the 'Wake Turbulence
Severity Classification Trial at Dubai', and 'Drones: their risk to aviation, the future and what the legislators are doing'.
One of the wake projects is called RECAT which is designed to recategorise the existing four wake turbulence
categories into six new wake categories.
