What is a tail scoop on a plane?

A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. The function of the tailplane is to provide stability and control.

What comes out of the back of an airplane?

Those white streaks planes leave behind are actually artificial clouds. They’re called contrails, which is a shortened version of the phrase “condensation trail.” Airplane engines produce exhaust, just like car engines do. As hot exhaust gases escape from a plane, the water vapor in the fumes hits the air.

What is tail setting angle?

Determination of tailplane incidence (nll = no-lift line) Here ε is the ‘downwash angle’ i.e. the mean angle at the tailplane that the airflow is deflected through by the wing, and ηT is the ‘tailplane setting angle’ defined as the angle between the wing and tailplane no-lift lines.

What is an overhead crew rest on a Boeing 777?

In 2003, Boeing introduced overhead crew rests as an option on the 777. Located above the main cabin and connected via staircases, the forward flight crew rest contains two seats and two bunks, while the aft cabin crew rest features multiple bunks.

What does the Boeing 777 interior look like?

The original 777 interior, also known as the Boeing Signature Interior, features curved panels, larger overhead bins, and indirect lighting. Seating options range from four to six abreast in first class up to ten abreast in economy.

Why doesn’t the Boeing 777 have a sidestick controller?

In designing the 777 as its first fly-by-wire commercial aircraft, Boeing decided to retain conventional control yokes rather than change to sidestick controllers as used in many fly-by-wire fighter aircraft and in many Airbus airliners.

Why did Boeing choose the 777 twin-engine design?

By 1988, Boeing realized that the only answer was a new clean-sheet design, which became the 777 twin-jet. The company opted for the twin-engine configuration given past design successes, projected engine developments, and reduced-cost benefits. On December 8, 1989, Boeing began issuing offers to airlines for the 777.
