LOWER DECK - 3 59 PASS.-4 45 PASS -5 73 PASS INCLUDES 9 IN LOUNGE The 747 can carry up to 363 passengers in an all-economy class layout as shown here at 34in seat pitch. Corresponding figures for the -4 and -5 are 311 passengers and 433 passengers respectively. The figures on the diagram represent the seats in each section of the cabin. Built-in stairs connect the decks; the flight deck leads off the top cabin In an all-freight layout the 747-3 can carry a grand total of 34 I25in x 88in pallets. Pallets for the lower decks could be square- loaded but on the top deck where they are placed side-by-side they would be tapered because of the fuselage curvature UPPER DECK 747-3 13 PALLETS 747-4 B PALLETS 747-5 Q PALLETS 747- 3 02 PALLETS 747-4 tH PALLETS 747-5 02 PALLETS 747-3 0 PALLETS 747-4 B PALLETS 747-5 B PALLETS factor on a 2,000-mile stage with a common revenue rate of 5.1 cents per mile would be 96 passengers, or 30.9 per cent (747-4), 100 passengers, or 27.6 per cent (747-3), and 108 passengers, or 24.8 per cent (747-5). Estimated selling prices of the 747 variants are: $15.8 million (£5.65 million) 747-3; $15.1 million (£5.4 million) 747-4; $16.6 million (£5.94 million) 747-5; $16.3 million (£5.82 million) 747-3C; $15.6 million (£5.57 million) 747-4C; $17.1 million (£6.1 million) 747-5C. The 707- 320B, incidentally, costs S7.25 million (£2.6 million). The twin-deck interior, with a third level right at the bottom for baggage, is capable of many combinations of passenger and mixed-traffic layout. The lower deck in particular offers good use of volume for pallets loaded squarely. With a change of fuselage section called for, it is interesting to note that Boeing have not chosen to propose larger sizes of freight pallet. All the interior drawings reproduced show the standard 125m x 88in pallet. In the case of the largest 747, the -5. the upper deck volume 01 i,500cu ft would accommodate 24 125in x 88in pallets, while the further 4,200cu ft on the forward lower deck would take nine pallets and five more pallets would go into the 2,200cu ft aft lower deck. The lower pit volume of 3,7OOcu ft would bring the total freight volume to no less than 21,600cu ft to give an average structural-limited maximum loading volume of 9.171b per cu ft The 747-5 in an all-freight version would have an operating empty weight of 261,4001b while the design zero-fuel weight would be 459,4001b, bringing the. maximum payload to 198,0001b.
