PMDG 777 FUEL PLANNER SKIN

Jet engine efficiency increases with velocity because the speed difference between the flight and the exhaust is lower. By increasing efficiency, a lower cruise-speed augments the range and reduces the environmental impact of aviation however, a higher cruise-speed allows more revenue passenger miles flown per day. Induced drag can be reduced by decreasing the size of the airframefuel and payload weight, and by increasing the wing aspect ratio or by using wingtip devices at the cost of increased structure weight.

The form drag is minimized by having the smallest frontal area and by streamlining the aircraft for a low drag coefficientwhile skin friction is proportional to the body's surface area and can be reduced by maximizing laminar flow. Parasitic drag is constituted by form drag and skin-friction dragand grows with the square of the speed in the drag equation. For powered aircraft, the optimum glide ratio has to be balanced with thrust efficiency. Aircraft efficiency is augmented by maximizing lift-to-drag ratiowhich is attained by minimizing parasitic drag and lift-generated induced dragthe two components of aerodynamic drag.ДЄs parasitic drag increases and induced drag decreases with speed, there is an optimum speed where the sum of both is minimal this is the best glide ratio. Boeing 777-300ER, Review, Description, Specification, and PriceДЄs lift and drag are functions of air speed, their relationships are major determinants of an aircraft's design efficiency. A subfield of fluid dynamicsaerodynamics studies the physics of a body moving through the air. The aircraft's maximum range is determined by the level of efficiency with which thrust can be applied to overcome the aerodynamic drag. A powered aircraft counters its weight through aerodynamic lift and counters its aerodynamic drag with thrust. It can be expressed in several ways, for example by the liters of fuel consumed per passenger per kilometer. Passengers 1-class.Fuel economy in aircraft is a measure of how much fuel an aircraft, or a fleet of aircraft of mixed types, needs to operate in relation to a service provided i. In addition, EFB includes the award-winning Jeppesen Airport Transfer Map application, which combines airport taxi charts with high fidelity, geographic references and appropriate navigation signals to show the flight crew right where they are at the airport surface.

This includes onboard performance tools that allow pilots to instantly calculate ideal speed and engine settings for aircraft, under any weather conditions, on any runway with any load. EFB provides technological advantages for safe, safe and efficient operations. Fuel burns are much lower by 21 to 22 percent lower per seat for a distance of When compared to A and A The new engine is considered to be the most powerful commercial jet engine in the world and currently holds the Guinness World Record for thrust.ДЇuel savings make it possible to offer lower prices to airline customers while minimizing environmental impacts. The Boeing ER has a mile-seat fee that is 18 to 20 percent lower than the A and A models.

And it uses the configuration of two classes and three classes, each of which can accommodate between and passengers. This aircraft has a cruising capacity of up to 7, nautical miles 14, km. The Boeing ER extends the capability range of the family, bringing the efficiency and reliability of twin engines to the long-term market. The first model of the ER was launched with ten aircraft orders from Air France, along with additional commitments on April 29, In JulyDubai-based Emirates agreed to buy 13 Boeing ER with four aircraft based on the company's order to be shipped during and the rest as an option to be sent from to Boeing combined several performance improvements for the ER version, developing its range and payload capabilities. The Boeing ER was launched in February by Boeing and GE Aircraft Engine at the request of customers requesting aircraft with extra flexibility to serve non-stop routes ordered by passengers.
