The boeing 747-200/300 what is the difference?

Question

The boeing 747-200/300 what is the difference?

Answer 1

Nothing. Just a wider 'hollow tube' full of people, sailing through the air.

Answer 2

The differences between the -300 and the -200 include a lengthened upper deck with two new emergency exit doors and an optional flight-crew rest area immediately aft of the flight deck. Compared to the -200, the upper deck is 23 feet 4 inches longer (7.11 m) than the -200.A new straight stairway to the upper deck instead of a spiral staircase is another difference between the -300 and earlier variants.[67] The staircase creates room below and above for more seats. With minor aerodynamic changes, Boeing increased the cruise speed of the -300 to Mach 0.85 from Mach 0.84. The -300 features the same takeoff weight.

Answer 3

747-200

The 747-200 has more powerful engines, higher takeoff weights (MTOW), and range than the -100. A few early -200s retained the three-window configuration of the -100 on the upper deck, but most were built with a 10-window configuration on each side.[118]

Several versions in addition to the -200 were produced. The 747-200B is an improved version of the 747-200, with increased fuel capacity and more powerful engines; it first entered service in February 1971.[119] The -200B aircraft has a full load range of about 6,857 nmi (12,700 km). The 747-200F is the freighter version of the -200 model. It could be fitted with or without a side cargo door.[119] It has a capacity of 105 tons (95.3 tonnes) and an MTOW of up to 833,000 lb (378,000 kg). It entered first service in 1972 with Lufthansa.[120] The 747-200C Convertible is a version that can be converted between a passenger and a freighter or used in mixed configurations.[67] The seats are removable, and the model has a nose cargo door.[119] The -200C could be fitted with an optional side cargo door on the main deck.[121]

The 747-200M is a combination version that has a side cargo door on the main deck and can carry freight in the rear section of the main deck. A removable partition on the main deck separates the cargo area at the rear from the passengers at the front. This model can carry up to 238 passengers in a 3-class configuration if cargo is carried on the main deck. The model is also known as the 747-200 Combi.[119] As on the -100, a stretched upper deck (SUD) modification was later offered. A total of 10 converted 747-200s were operated by KLM.[119] UTA French Airlines also had two of these aircraft converted.[122][123]

A total of 393 of the -200 versions had been built when production ended in 1991.[124] Of these, 225 were 747-200s, 73 were 747-200F, 13 were 747-200C, 78 were 747-200M, and 4 were military.[125]

Many 747-200s are still in operation, although most large carriers have retired them from their fleets and sold them to smaller operators. Large carriers have speeded up fleet retirement following the September 11th attacks, scrapping some or turning others into freighters.[citation needed]

747-300

The differences between the -300 and the -200 include a lengthened upper deck with two new emergency exit doors and an optional flight-crew rest area immediately aft of the flight deck. Compared to the -200, the upper deck is 23 feet 4 inches longer (7.11 m) than the -200.[126] A new straight stairway to the upper deck instead of a spiral staircase is another difference between the -300 and earlier variants.[67] The staircase creates room below and above for more seats. With minor aerodynamic changes, Boeing increased the cruise speed of the -300 to Mach 0.85 from Mach 0.84 on the -100/-200.[126] The -300 features the same takeoff weight. Two of the three engine choices from the -200 were unchanged in the -300, but the General Electric CF6-80C2B1 was offered instead of the CF6-50E2 offered on the -200.[67]

The 747-300 name, which was proposed for a variant that was never launched, was revived for this new version, which was introduced in 1980. Swissair ordered the first 747-300 on 11 June 1980.[127] The 747-300 first flew on 5 October 1982. Swissair was the first customer to accept delivery on 23 March 1983.[31]

In addition to the passenger version, other versions were available. The 747-300M has cargo capacity in the rear portion of the main deck similar to the -200M, but with the stretched upper deck it can carry more passengers.[128] The 747-300SR is a short range version to meet the need for a high-capacity domestic model. Japan Airlines operated such aircraft with more than 600 seats on the Okinawa–Tokyo route and elsewhere. Boeing never launched a newly built freighter version of the 747-300, but it modified used passenger -300 models into freighters starting in 2000.[129]

A total of 81 aircraft were ordered, 56 for passenger use, 21 -300M and 4 -300SR versions.[130] The 747-300 was soon superseded by the launch of the more advanced 747-400 in 1985, just two years after the -300 entered service.[131] The last 747-300 was delivered in September 1990 to Sabena.[67][132]

Today, most -300 aircraft are still active, despite a significant loss of interest in the series amongst large carriers who have since sold them to other smaller airlines. A few of these aircraft have surprisingly been converted to cargo operations, though none of any -300s have been delivered new as freighters. Carriers still using these aircraft include Japan Airlines, Qantas, Pakistan International Airlines, Air India and Saudi Arabian Airlines.

Answer 4

bigger upper deck

Answer 5

Significant differences are as follows:

(a) The differences between the 747-300 and the 747-200 include a slightly more lengthy upper deck.

(b) A straight stairway to the upper deck instead of a spiral staircase is another difference between the 747-300 and earlier variants.

(c) Boeing 747-300 cruise speed is Mach 0.85 as compared to Mach 0.84 on the 747-200.

However, the 747-300 features the same takeoff weight as compared to 747-200.
