Boeing

Take-off speeds for the Boeing 737 range between 130 kts and 160 kts

Landings speeds for the Boeing 737 range between 110 kts and 170 kts.

You can get a used Boeing 727 for around £5 million depending on it's condition and the seller.

747-400 can hold up to 524 with a business/economy configuration.

The landing speed for a Boeing 737 typically ranges from about 130 to 150 knots, depending on the specific model, weight, and environmental conditions. Factors such as flap settings and runway conditions can also influence the exact landing speed. Pilots calculate the appropriate landing speed for each approach to ensure safe and efficient landings.

Joseph Sutter is the father of the Boeing 747

Jet A, Jet A1, Jet A50, JP 4, JP 5, JP 8, Jet B, RT and TS-1. All are kerosene based fuels.

There are many different types of 747. The average landing speed would be 150 knots for a 747.

It can be anywhere from about 120 to 180 knots depending on gross weight

It depends what type. The Boeing 777-200 holds 305 passengers and the Boeing 777-300ER can hold 365 passengers.

747

This can vary within different aircrafts within both different and the same airlines, some airlines can carry up to 452 passengers on their 747's and only 344 on another one of their aircrafts.

it depends on what type of aircraft your flying, the runway length, and the weather. here are two common aircraft flap settings for standard takeoff use: Boeing 737: set flaps to 5 cessna 172: set flaps to 10 these are two common flap settings for the Boeing 737 and cessna 172. remember, different aircraft have differnet flap settings based on weather and runway length.

Around 41,000 feet.

About one minute from brake release to lift off at maximum take off weight.

About 160-190 miles per hour.

in a nut shell, not too knowledgable on the system but:

it consists of the following

1 x forward outflow valve mainly for cooling of the E&E bay and doesnt do much with pressurization it just creeps open and allows for air to exit and to circulate and cool down the avionics

2 x negative pressure relief which are simply doors that require maybe .1 PSI to open, they protect the cabin incase outside pressure is more than inside pressure (diving through the ceiling i think they call this)

1 x outflow valve this is the main controller of the pressurization system. It is whats connected to the rate controller. The rate controller is set by the pilot and he chooses what alt he wants the cabin at and how fast he wants to get there. This rate controller senses the pressure inside the cabin and tells the outflow valve whether to open more allowing air to escape allowing pressure to decrease or to close the outflow valve and keep the air in, allowing pressure to increase. This is the only real ventilation you get in the aircraft. Yes those nozzles above your seat are baggage compartment "fresh" air not real, new air. To finish things off the air in the first place comes from bleed air source which are your engines. Air is taken from 2 compressor sections on the engine itself and is bled into cabin after going to filters, ducts, and i believe cooling systems as well. The outflow valve it self is opened by the power of vaccuum and is closed by the spring inside.

2 x safety relief valves which are there to act as another negative pressure relief, they open slightly above max differential pressure maybe 8.7 psi vs. outflow opening at 8.5 psi this is to allow the outflow valve to do its other job and open at max diff before the safety valve does. its last job is to dump all pressure as per pilot wants, or landing

1 x aft outflow valve which is mainly for the dumping of pressure in emergency. the landing gear squat switch also opens this valve upon landing to depressurize. its at the back of the plane in order to be able to suck air from the front and anywhere forward of the main aft section of aircraft where there could be a smell or smoke ect

thats all i got. hope it helps!

It depends on the type and how the airline aranges the seats. Typically 467 seats.
747-400 ER 416 seats 23 first class 80 business class 313 economy class

What they might do is continue on to 8x8 or maybe 8x7, although it really is unknown. Some also speculate that they will skip 797, and move striaght on to 808. This is because 8 is what Boeing is using to denote new planes (787, 747-8). Or they might just get rid of the XyX naming system entirely. This is a possiblity mainly because it was the Boeing 787 Dreamliner. Not just the 787

There are several different models of the 747 produced.

Their maximum rage varies from 5,000 to 8,000 nautical miles.

The Boeing 747's cabin width is 20 feet (6.1 m) that is enough to have three seats, and aisle, four seats, and after another aisle is has another three, its a thick plane.

The MD-80 is not made by Boeing, it is made by McDonnell Douglas. Different variants of the MD-80 can hold different amounts of fuel. The lowest being the MD-87 at 5840 gallons, the highest being the MD-83 at 7000 gallons.
