Why does the 757 produce so much wake turbulence?

Due to the wing design of the 757, it can produce strong wingtip vortices. This is what causes wake turbulence for other aircraft when landing or taking off. In some cases, it can be stronger from the 757 than larger widebodies like the 767 or even the 747.

The heavier the aircraft is and the slower it is moving, the stronger the vortices. That means that heavy aircraft such as a the Boeing 747 — and of course the Airbus A380, which is even bigger and heavier — are most prone to generating this kind of effect.

Due to the fact that most of the wake turbulence (vortices) of an aircraft in flight is due to the air's interaction with the wing, the 757 essentially using a heavy aircraft's wing (767) causes it to have an unusual amount of wake turbulence compared to its size.

However, the vortex strength from an aircraft increases proportionately to an increase in operating weight or a decrease in aircraft speed. Since the turbulence from a “dirty” aircraft configuration hastens wake decay, the greatest vortex strength occurs when the generating aircraft is HEAVY, CLEAN, and SLOW.

Why does 757 have bad wake turbulence? While tests on the 757 are under way, those in the industry speculate that the aircraft's unique wing design may be the biggest reason it produces so much more turbulence than other planes its size.

On Monday 3 March 1997 at 1014 hours, privately owned and operated Cessna 185 encountered wake turbulence from previous departing aircraft, the pilot lost control of the aircraft at a height from which recovery was not possible and the aircraft descended to the ground.

A: The 757 is one of my favorite airplanes. The lines are beautiful, and the performance is unmatched by other airliners. It has a higher thrust-to-weight ratio, resulting in spectacular climb performance.

MORE DETAILS

With its new wing and high thrust engines, the 757 could cruise at a higher altitude than the advanced 727-200, allowing greater fuel savings and use of higher airways. The 757's four-wheel main landing gear units allowed operations on runways previously closed to commercial planes of its size.

He said the power and thrust was the best of any commercial airliner in its class and pilots liked the performance and quick response from the engines (AA had Rolls-Royce) and that was fun to fly. He said though his copilot had to immediately retract flaps on his command as the “757 will overfly the flaps on takeoff”.

Which Plane Handles Turbulence Best? The bigger the plane, the better! Any plane can experience turbulence, but larger planes weigh more and don't feel the impact of wind changes as much as a smaller plane. Specifically, the Airbus A380 handles turbulence very well!

MORE DETAILS

While no aircraft can avoid turbulence, passengers may feel less turbulence in widebody aircrafts, as they're larger and heavier airplanes.

The best plane for turbulence: Boeing 787-9 The original image has been cropped. This plane boasts on of the largest wing loading in commercial planes: 670 kg/m2. For comparison, the wings can take 60% per square meter than those of an Embraer ERJ-145. Just by this value, you can expect a smoother ride on the 787.

AVOID THE AREA BELOW AND BEHIND THE WAKE GENERATING AIRCRAFT, ESPECIALLY AT LOW ALTITUDE WHERE EVEN A MOMENTARY WAKE ENCOUNTER COULD BE CATASTROPHIC. A common scenario for a wake encounter is in terminal airspace after accepting clearance for a visual approach behind landing traffic.

Airplanes are built very sturdily. In fact, there's a lot of countermeasures built into the engineering of an airplane much like a car has different things to make a smooth ride on a bumpy road, airplanes have so many parts to it that's built into the aircraft to be able to deal with and safely handle the turbulence.

Severe turbulence can cause a plane to drop so suddenly that pilots temporarily lose control. But, again, that's not enough to crash the plane. That's not to say it's never happened.

easyJet did not have a fleet strategy to include the 757. Indeed, it would not have had a 757 flying for it at all were it not for a brief spell of crew shortages. According to conversations on the Aviation Forum, easyJet wet leased all four of its 757s to operate flights over the busy summer season that year.

Range: The 757 had the range to fly transatlantic from the northeastern coast of the US and Canada to Western Europe, and not much more, but often that was just enough. Today there are many more routes possible in Europe since the end of the Cold War, which a 757 wouldn't be able to do, but the 787 can.

At the 65-hour minimum guarantee, a Boeing 757 first officer starts out making at least $55,000 per year and by year 10 will be making more than $120,000 per year, not including per diem. By comparison, a captain at Delta in the same airplane starts at $206 per hour year one, and by year 10 makes $222 per hour.

Wake turbulence from a large enough aircraft will cause the one following to flip and possibly crash into the ground.

Wingtip vortices make up the primary and most dangerous component of wake turbulence. 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.
