Its aerodynamic design, particularly its wing, makes the 747 quicker than other aircraft. To minimize drag and increase speed, the 747’s huge wings have a 37.5-degree high sweep angle. For the optimum flying characteristics, Boeing has optimized the design. Additionally, the fuselage has been modified to provide the commercial aircraft with the best conditions possible for effective flying behavior. So, the question of why we can’t often get the altitudes we want on shorter trips isn’t a mystery at all. The airspace in many parts of the country is so complex, that an arriving or departing flight a hundred or more miles away matters.

These recreational airplanes are less powerful and designed for shorter flights. Most Cessna 172s have a maximum altitude of 13,000 to 15,000 feet, which is much lower than the previously discussed models. These airplanes need to make sure that they stay within this range to be as safe as possible.

Additionally, flying at higher altitudes helps to avoid obstacles like mountains and weather disturbances. The 747’s ability to fly at higher altitudes is made possible by its powerful engines and aerodynamic design. The Boeing 747 can increase its velocity by using these jet streams because of its capacity to fly at high altitudes.
Payload
If a plane accidentally goes above its designated cruising altitude, the pilot will typically descend back to the correct altitude. This could be due to an autopilot or human error, or a temporary deviation for air traffic control instructions. The descent to the correct altitude ensures that the aircraft remains within the designated airspace and follows the necessary flight regulations. At higher altitudes, the air becomes thinner, which reduces drag and increases fuel efficiency.
How many passengers can be seated on a plane?
I have been flying the PMDG 737 for quite a while and thought that the FMC's would be similar. They are very much the same except in entering the cruise altitude. The higher value is perfect for piston engines and props, and the lower one for turbojets (think fighter aircraft engine).
Its fuselage is stretched by 18 feet (5.5 m) to 250 feet (76 m), making it the longest airliner until the 777X, which first flew in 2020. While keeping its basic structure and sweep, the wing is thicker and deeper, holding more fuel, and wider with raked wingtips. The final aircraft, a 747-8F, was delivered to Atlas Air on January 31, 2023. The 747 is a four-engined jet aircraft, initially powered by Pratt & Whitney JT9D turbofan engines, then General Electric CF6 and Rolls-Royce RB211 engines for the original variants. With a ten-abreast economy seating, it typically accommodates 366 passengers in three travel classes.
A Boeing 747 has a cross height of 35,105 ft, while the Embraer climbs 190 to 39,370 ft. At the bottom of this page, you will find an overview of the cruising altitudes of the most common aircraft at Schiphol. During takeoff and landing, a 747 flies at relatively lower altitudes compared to its cruising altitude. This is necessary to ensure proper acceleration during takeoff and a gradual descent for landing. The specific altitudes during takeoff and landing can vary depending on factors such as runway length, aircraft weight, and airport regulations. Aircraft wings can only produce so much lift, and the higher you go the thinner the air is, meaning the less lift a wing can generate.
Cruise to Italy and contemplate world-class art and architecture, timeless natural scenery and a food and wine scene against which all others are judged. Roam the lively streets of the Eternal City of Rome, and see the Colosseum in its massive, ancient glory. Check out the unmistakable Duomo ('dome') of Florence, and taste your way through the wineries of the nearby Chianti hills. Ride a gondola down the serpentine canals of Venice, see the brilliant gold mosaics of St Mark's Basilica, or hike volcanic Mount Vesuvius and refuel with a classic Neapolitan pizza in Naples.
To find out what altitude works on a short flight, all I can suggest is trial and error, or maybe ask the controller if the frequency quiets down so you can plan for the next time. We started filing FL250, a good altitude for the Beechcraft King Air 350i in terms of speed and fuel efficiency. But as we flew south into the busy arrival and departure corridors for O’Hare, we were sent down. I just bought the 747 and was setting up my first flight in the FMC.
Marked by its distinctively recognizable hump, this iconic airplane is a symbol of great engineering, innovation and often noted as an outstanding work of architecture. Aircraft are extremely fast – certainly faster than your car or bicycle. Of course, the aircraft, its weight, and the current atmospheric conditions are of importance.
When it comes to aviation, airplanes, and flight dispatching, a key consideration for the career is understanding what the ideal cruising altitude for airplanes is. Cruising altitude is the name given to the height that an aircraft will achieve for most of the flight or travel. This is the most constant altitude that most aircraft will experience, which is why they are deemed to be “cruising” when they reach this altitude. Cruising altitude is also the portion of a flight where aircraft are the most fuel-efficient because of the consistency in speed and engine use. What is cruising altitude, and how does it fit into different aircraft? Sheffield School of Aeronautics explores more in the following article.
You can see altitudes issued to other flights on flight planning services such as Fltplan.com. Those altitudes are accurate in that they were issued by center computer as an initial clearance. The historic 747, dubbed the ‘Queen of the Skies,’ revolutionized air travel as the world’s first twin-aisle airplane and enabled more people to fly farther, faster and more affordably than ever before.
Scroll down to see the number of seats in the most common planes at Schiphol. Cruise altitude may be assigned by ATC for separation (IFR especially, or in other controlled airspace -- since, in the US, these altitudes would be Class A and controlled airspace). For example, when you request a DUAT(S) briefing, it will usually give suggested ATC routing and also altitude assignments (along with what's most frequently used).
ECON speed will also be higher at higher altitudes because the density of the air is lower. The cruising altitude of an aircraft depends on its type, size, performance capabilities, and the specific flight conditions. Larger commercial aircraft like the 747 generally fly at higher cruising altitudes, while smaller regional aircraft may operate at lower altitudes. In exceptional circumstances, a 747 may need to fly above its designated cruising altitude. This could be due to air traffic control instructions, avoiding severe weather, or other factors affecting the safety and efficiency of the flight. However, such deviations from the designated cruising altitude are typically temporary and occur on a case-by-case basis.
This altitude allows the aircraft to operate at optimal performance, providing a smoother and more fuel-efficient flight experience for passengers. The cruising altitude is determined by a combination of factors, including air traffic control instructions, weather conditions, and the weight of the aircraft. Pilots determine the best cruising altitude based on several factors. They consider air traffic control instructions, weather conditions, aircraft weight, and performance data. By analyzing these factors, pilots can select the most optimal cruising altitude that ensures a safe and efficient flight for the passengers and crew.
