Is Pfft Rude?
PFFT is “An Expression Of Dismissal”. The interjection PFFT (pronounced “pufft”) is used to dismiss something that someone has said or typed. When used as a direct response to a statement by another person, PFFT can often be considered quite rude.
What does Pffffft mean?
It’s an onomatapoeic exclamation or interjection. It’s also eye dialect (a literary device that spells out sounds or respells normal words as a visual cue or special effect). “Pfft” is used to signify sarcasm or disagreement.

What does GSE stand for in aviation?
GSE’s main purpose is to support the safe operations of the aircraft after landing and before taking off again. Ground Support Equipment usually involves a variety of aircraft mobility, ground power operations, and cargo and passenger loading operations.

What is a GPU in aviation?
Description. A Ground Power Unit (GPU) can be either a fixed or mobile unit which can be connected to the electrical system of an aircraft while on the ground to provide either 120V AC or 28V DC power. Ground power units usually consist of a generator powered by a diesel engine but may found in other configurations.
How much does AK loader cost?
The Emerson K loader, model A/S 32H5A, aircraft cargo loader and Condec K loader have a service deck min/ max height of 37.5″- 156″ and a max load weight of 25,000 lbs. Pricing starts at $48,000.
What do winglets do?
Winglets reduce wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplane’s wing and that on the lower surface. High pressure on the lower surface creates a natural airflow that makes its way to the wingtip and curls upward around it.
Why do 777 not have winglets?
Why does the 777 not have winglets? One reason that the 777 does not feature such wingtip extensions is the operational limits these would place on the aircraft. The 777-200LR and -300ER variants of the aircraft have a wingspan of 64.8 meters. This only just falls below the upper limit for the ICAO’s aerodrome code E.
How much do winglets cost?
Winglets cost anywhere from $500,000 for a 737 to more than $2 million for bigger planes. But the payoff can be rapid. Southwest Airlines estimates that it saves 54 million gallons of fuel every year thanks to equipping 93 percent of its fleet of 737s with winglets.
Do winglets increase lift?
Winglets increase an aircraft’s operating efficiency by reducing what is called induced drag at the tips of the wings. The effect of these vortices is increased drag and reduced lift that results in less flight efficiency and higher fuel costs.
Who invented winglets?
William E. Somerville
What is the difference between winglet and sharklet?
To the naked eye, the difference between sharklets and winglets is in name only. Their purpose is to cut down on fuel—between 3.5 to seven per cent—by reducing aerodynamic drag, which they do by literally slashing through the air. Whether they’re called sharklets or winglets, those wing tips are no small matter.
Why are planes wings curved?
Airplanes’ wings are curved on top and flatter on the bottom. That shape makes air flow over the top faster than under the bottom. As a result, less air pressure is on top of the wing. This lower pressure makes the wing, and the airplane it’s attached to, move up.
What are the 4 Forces of Flight?
It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.
What is a winglet in Wings of Fire?
(The winglets are not to be confused with Winglets, which are short e-books in Wings of Fire.) Jade Mountain Academy is an intertribal school located within Jade Mountain and was founded by the dragonets of destiny after the War of SandWing Succession.
How do delta wings work?
At low speeds, a delta wing requires a high angle of attack to maintain lift. As the angle of attack increases, the leading edge of the wing generates a vortex which energises the flow on the upper surface of the wing, delaying flow separation, and giving the delta a very high stall angle.
What is the most efficient wing shape?
elliptical wing
Why are elliptical wings better?
“…the real advantage of the elliptical wing turned out to be its low induced drag at very high altitudes, such altitudes not having been considered during the design, but realised during the war, helping to keep Spitfire in the front line during rapid development under Joe Smith.
Are delta wings more maneuverable?
Low wing loading permits higher maneuverability. At a high angle of attack, the leading edge creates strong vortices that allow a delta wing to maintain lift at very high angle, which is advantageous in combat. The high sweep angle reduces aerodynamic drag in supersonic flight.
Why are Wings swept?
Swept wings, however, are designed to reduce turbulence by slowing down the air as it moves across the surface of the wings. As previously mentioned, swept wings are longer than straight wings. Therefore, air moves more slowly across them, which reduces the amount of turbulence the airplane encounters.
What is canard delta wing?
A canard is an aeronautical arrangement wherein a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft. The term “canard” may be used to describe the aircraft itself, the wing configuration, or the foreplane.
What are the advantages of swept wings?
In transonic flight, a swept wing allows a higher Critical Mach Number than a straight wing of similar Chord and Camber. This results in the principal advantage of wing sweep which is to delay the onset of wave drag. A swept wing is optimised for high speed flight.
What causes spanwise flow?
Well, spanwise flow happens because air behaves like a liquid and will take the path of least resistance. In this case it’s along the swept leading edge it tends to move as that offers less resistance than going over the wing to some degree (very simply explained – there’s more to it).
