On March 5, 1966, BOAC Flight 911 from Tokyo to Hong Kong, a Boeing 707, broke up in CAT, with the loss of all persons (124) on board after experiencing severe lee-wave turbulence just downwind of Mount Fuji, Japan. The sequence of failure started with the vertical stabilizer getting ripped off.
WHAT IS TURBULENCE? Turbulence or pockets of disturbed air can have many causes, most obviously the unstable weather patterns that trigger storms, according to an industry briefing by planemaker ...
Clear-air turbulence experienced during airplane flight, as well as poor astronomical seeing (the blurring of images seen through the atmosphere). Most of the terrestrial atmospheric circulation . The oceanic and atmospheric mixed layers and intense oceanic currents.
The purpose is to ensure that turbulence or gusts will not result in the airplane flying below V REF at any point on the approach. [30] Also known as V FLY. V BE: Best endurance speed – the speed that gives the greatest airborne time for fuel consumed. [citation needed] V BG
Wake turbulence is especially hazardous in the region behind an aircraft in the takeoff or landing phases of flight. During take-off and landing, an aircraft operates at a high angle of attack. This flight attitude maximizes the formation of strong vortices. In the vicinity of an airport, there can be multiple aircraft, all operating at low ...
Most don't have any issues at all, but in certain cases, the atmosphere can cause issues with turbulence when flying near or through storms." While such severe cases are rare, the potential for ...
Forces of flight on a powered aircraft in unaccelerated level flight. Understanding the motion of air around an object (often called a flow field) enables the calculation of forces and moments acting on the object. In many aerodynamics problems, the forces of interest are the fundamental forces of flight: lift, drag, thrust, and weight. Of ...
A photo shows the inside of an Air Canada jet during a flight from Vancouver to Singapore after it encountered turbulence on Oct. 11, 2023, sending passengers' food and drinks flying around the cabin.
