DC-7 size and dimensions

The DC-7 is 34.21 m (112.2 ft) long, has a wingspan of 38.86 m and stands 9.65 m tall. That makes it the #1 longest of 26 piston & light aircraft in our database — longer than 96% of them. With 152.1 m² of wing, the wing loading at maximum weight is about 426 kg/m².

DC-7 weight and fuel

The maximum take-off weight is 64,864 kg (143,000 lb) and it may land at up to 49,000 kg — 76% of take-off weight, so after a short flight it has to burn off fuel before landing at full weight. Among piston & light aircraft it ranks #1 of 16 by weight. The tanks hold 29,620 litres (7,825 US gallons), about 23.7 tonnes of jet fuel.

DC-7 speed and range

It cruises at about 557 km/h (301 knots), faster than 96% of piston & light aircraft. Its range of 9,069 km (4,897 nm) is enough to fly non-stop from Dubai to Beijing (7,900 km) — about 16.3 hours at cruise speed. On final approach it flies at around 110 knots (204 km/h). Its ceiling is 21,700 ft (6,614 m).
