While a 747 can technically fly at various altitudes, it is usually restricted to a specific range. This range is determined by factors such as air traffic control instructions, weight of the aircraft, and weather conditions. The 747 is designed to operate most efficiently at higher altitudes, typically ranging from 35,000 to 45,000 feet. Airlines may have their own performance tables, choosing a custom balance of efficiency and speed.
ITALY CRUISES
Most airlines like to reach this high cruising altitude because of the costs that they will save on fuel, which is obviously a huge draw for airlines that are looking to save money. This high cruising altitude also means that there could be smooth communication between air traffic controllers and pilots because of how far apart the other aircraft will be at such altitudes. In fact, most aircraft that are in the same area stay around 1,000 feet away from each other so that they do not collide.
Speed
When it comes to performance, with a jet you want to fly as high as possible. The only reason not to do so is total distance; on a short hop there is not enough flying time to climb all the way up. The aircraft designer will use something like that to calculate typical values, which will be included in the aircraft's operating handbook. The larger planes, such as the Boeing 747, 777, 787 and the Airbus A330 and A380, have much more seats than the smaller Embraer 190, Boeing 737 and Airbus A320. The A380 can transport most passengers (516 seats), followed by the Boeing 747 and 777 (408 seats).
Design
Even if you stick to 'mainstream' Italian destinations, you can still spice up your time in Italy. Ride a vaporetto (a local form of taxi boat) from Venice to the colourful island of Burano, or take a westward train ride from the port city of La Spezia to the lush coast of Cinque Terre. These are great alternatives to going south and east to Florence or Pisa. What is showing up in the LEGS page is the "predicted best place" to initiate your step climb - It's saying you can climb, not saying you must (and deftinatley not saying you will). Modern planning systems can take into account weather factors such as winds aloft and turbulence to pick the most efficient route. He is passionate about antique airplanes and has restored many of the Wright brothers' planes, including the 1918 Curtiss Jenny and the 1903 Wright Flyer.
Does the cruising altitude affect the speed of a 747?

The Airbus A380 can reach speeds of more than 1,000 kilometres per hour! Now the Boeing 787 Dreamliner (907 km/h) and Boeing 777 (905 km/h) aren’t that fast, but still three times faster than a Formula 1 racing car. See below the speeds of the most common aircraft on Schiphol. Unless you use the Mode Control Panel MCP to select 34000ft on the autopilot, and then go to the VNAV/CRZ page and insert 34000ft into the cruise altitude and excecute. And you wouldn't do that without an ATC clearance even with it annotated in the flightplan.
How many passengers can be seated on a plane?
He is also a pilot and mechanic who has worked for Capital Airlines, Bendix Corporation, and American Airlines. The other day we were going to Louisville Muhammad Ali International Airport (SDF) and Fltplan.com suggested FL260 for cruise. I never expected it to work, but since it was a slightly different route, we decided to try. As we were stepped up to FL190 there was a break on the frequency and I asked the controller if he thought FL260 was really going to work for us. On December 6, 2022, the final 'Queen of the Skies' ever to be built rolled out of Boeing's Everett factory, ending its historic 54-year production run.

To yield more precise results, both formulas will be longer, but these are the major factors for optimum lift coefficient. In addition to being long and thin, the wing’s high aspect ratio increases lift and lowers fuel consumption. Plus, the wing comes with a supercritical airfoil, decreasing drag at high speeds by delaying the introduction of shock waves and having a downward slope at the trailing edge. But what about that shorter trip—a couple hundred miles or so—especially if you’re flying near large metropolitan areas? Knowing what cruise altitude works on those routes is a mystery. In an average month like September, 746 aircraft will arrive at Schiphol and an almost equal number leaves again.
Airliner proposal
As the aircraft consumes fuel, its weight decreases and the optimum altitude for fuel economy increases. For traffic control reasons it is usually necessary for an aircraft to stay at a cleared flight level. On long-haul flights, the pilot may ask air traffic control to climb from one flight level to a higher one, in a manoeuvre known as a step climb. The altitudes are based on the aircraft, its weight, and the current atmospheric conditions. This is the sweet spot where plane fly as fast as possible, but burn the least amount of fuel.

Each individual airplane will have a different “sweet spot” that translates to the most efficient ride for them. Obviously, not every flight on a 747 will be operated under this very specific condition, but when the atmospheric conditions and weather allow for it, every pilot should aim for this height. This is because a heavier aircraft should fly faster to generate the required lift at the most efficient lift coefficient.
The pressurization system ensures that passengers experience a similar level of comfort and oxygen as they would at lower altitudes. Back to RTE, Activate, check altitude in LEGS pages and see cruise altitude is set at FL390 not FL330. Back to PERF INIT and double check that CRZ ALT is at FL330. The altitude you request somewhat depends on aircraft performance, I would imagine, but obviously any ATC clearance must be adhered to unless amended. Hopefully one of the commercial pilots can fill in more of the blanks, though. The most recent design and materials are included in the GEnx to enhance performance, lower maintenance costs, and consume less fuel.
Most commercial airplane manufacturers have different models of airplanes that are each used for different purposes because of the characteristics that each has. Closely related to the 747, a 737 jet has a very similar cruising altitude. The maximum cruising altitude for the new generation of 737 planes is 41,000 feet. At this altitude, 737 jets can still have great fuel efficiency and safety standards thanks to avoiding powerful winds and bad weather.
This renowned Boeing commercial airplane not only represents the peak of commercial aviation engineering but also enthralls us with its breathtaking speed as it easily travels great distances. Consider aircraft weight, forecast air temperature, winds, and any expected turbulence levels, and you can find the answer in your airplane documents. Or better yet, any of several performance calculation services can nail the answer for your specific airplane. The first Boeing Freighter took to the skies on February 8, 2010. The airplane followed a route over Western Washington, where it underwent tests for basic handling qualities and engine performance.
The Intercontinental began its flight test program March 20, 2011, taking off from Paine Field in Everett, WA. It landed four hours and 25 minutes later at Boeing Field in Renton. On Jan. 22, 1970, the first 747 entered service on Pan Am Airlines’ New York–London route.
However thinner air creates less drag, so the higher an aircraft flies the less fuel it uses for the same amount of time. Now you know the cruise, landing, and takeoff speed of a 747. The plane soars through the air at extraordinary speeds thanks to a combination of strong engines, clever utilization of jet streams, and aerodynamic brilliance.
On May 1, 2012, the first 747-8i departed Paine Field in Everett, WA bound for Frankfurt, Germany after being delivered to Lufthansa. The Boeing Dreamlifter takes off for its first flight, on September 9, 2006. Boeing has studied a number of 747 variants that have not gone beyond the concept stage.
