A question about Boeing commercial jets?

Question

Boeing's products include:

737

747

767

777

787 (dreamliner)

I am aware that the 747 has 4 engines

What is the difference between 747's e.g. a 747 400 and a 747 100?

What are the difference between the aircrafts that have just twin engines?

And boeings that are out of production such as 727, 757 etc Do some airline companies still use these, do they still fly?

Thanks

Answer 1

Just retired out of an executive 727.

Answer 2

The differences between the 741 and the 744 include

1) powerplant

2) cockpit avionics

3) fuseloge

The 741also requires 3 people to fly it (ie Captain, First officer, and flight engineer) compared to the 2 people it takes the 744 to fly (ie Captain and First Officer)

Also the 741 is almost non existant in the commercial airline arena because of its age (it came out in the 1960's), but the 744 is still largely operated, though it is being fazed out by most airlines in favor of 777s , A340s and in the case of Lufthansa the 748.

As for the 727 and the 757 - they absolutely do still fly, not as many 727's  as there used to be though :( , but the 757 is still in its prime as an airliner.

Answer 3

any airplane, even if out of production can be used if they are properly operated and maintained. i believe that the Boeing/MD-83 is out of production but Alaska Airlines, and other airlines are still operating them.

the difference between a 747-100 and a 747-400 is length and sometimes width of the fuselage, the 747-100 has a shorter fuselage, compared to the 747-400, and holds less passengers.

for a twin engine aircraft, this applies as well... a Boeing 737 - 800 holds more passengers and is slightly longer than a Boeing 737-400.

Answer 4

The 747-400 for example the 400 is the series number the 100 being the first the 200 having new upgrades and thats wat the numbers are for simply to help designate what upgrades they've been fitted with ie new engines longer gear and some cases removal of passenger sections like 737-200 had weird little engines the 800 series however has wingtips and new engines and state of the art avionics suitet

Answer 5

The 747-100 is oldest serie in the 747 family (y1967),

while the 747-400 is the newest (y2007) taking benefit of 40 years of experience and technical growth: new engines, more capacity, greater fuel efficency, new avionics and 10 times the cost! (well blame on inflation ;-)

I have flown on a 757 (Delta Airlines) last february.

Aircraft usually have a "three steps" lifecycle:

Brand new - used by most prestigious airlines

Midlife - sold to and used by "cheaper" airlines

Old - sold to and used by 3rd world countries' airlines (no joke)

... so a lot of soon-to-be-dismissed aircraft end their life in Africa or South America... and that's a good reason to take into account when explaining the higher accident rates in those countries compared to US/Europe

Answer 7

youve got lots of answers!...but i think youlle find that the 747-200 was the classic jumbo and when the aircraft is manufactured to carry more people they add a section or slug to lengthen the aircraft...i believe the latest version is a 747-400 which is a lot longer than a 200...737 is a mini...757 is a bit bigger and very popular with holiday companies 767 is a wide bodied version and 777 is a long distance version...you will see the old 727's about but are generaly used in poorer countries or for freight...
