The Lockheed L-188 Electra is an American turboprop airliner that was first flown in 1957. It was the first large turboprop airliner built in the United States. The Electra has had a long and varied history, serving as a passenger aircraft, cargo plane, and aerial firefighter. With a maximum takeoff weight of 116,000 lbs, the Electra's fuel burn rate is estimated to be around 5000 lbs during the first hour of flight and 4000 lbs for each subsequent hour. However, some sources suggest a slightly lower fuel burn rate of 3000 to 4000 lbs per hour. The Electra's fuel capacity has varied across different versions, with the long-range version capable of holding 6,940 US gallons of fuel.

The Lockheed L-188 Electra burns 5000 lbs of fuel in the first hour
The Lockheed L-188 Electra is an American-built turboprop airliner that first flew in 1957. It was the first large turboprop airliner built in the United States and is known for its high power-to-weight ratio, large propellers, and short wings.
The fuel consumption of the Lockheed L-188 Electra depends on various factors, including the aircraft's weight, the number of engines, and the flight phase (climb or cruise). According to sources, the Electra burns approximately 5,000 lbs of fuel during the first hour of flight, with fuel consumption decreasing by about 200 lbs for each subsequent hour. This estimate is supported by a pilot who flew the Electra for around eight years and recalled that it burned 5,000 lbs of fuel in the first hour and 4,000 lbs in each following hour.
Another source mentions that the Electra burns approximately 3,000 to 4,000 lbs of fuel per hour during the cruise phase, with an average total fuel burn of 5,000 lbs in the first hour. The variation in fuel consumption may be due to different flight conditions, payloads, or aircraft configurations.
It's worth noting that the Lockheed L-188 Electra has different variants with varying fuel capacities. The Model 188A has a fuel capacity of 5,450 US gallons (20,600 L), while the longer-range 188C can hold 1,000 US gallons (3,800 L) more fuel.

It burns 4000 lbs of fuel in each subsequent hour
The Lockheed L-188 Electra is a large turboprop airliner built by Lockheed. It was first flown in 1957 and was the first large turboprop airliner built in the United States.
The Electra has a high power-to-weight ratio, huge propellers, very short wings, large Fowler flaps, and a four-engined design. These features give it airfield performance capabilities that even today's jet transport aircraft may struggle to match, particularly on short runways and high-altitude airfields.
The fuel consumption of the Electra depends on its weight and the phase of flight. During the climb, the Electra uses 100 lbs of fuel per minute. During cruise flight, the Electra burns 5000 lbs of fuel per hour for the first hour with a maximum takeoff weight of 116000 lbs. In subsequent hours, the fuel burn decreases by approximately 200 lbs per hour.
Based on this information, if the Electra burns 5000 lbs of fuel in the first hour, it will burn 4000 lbs of fuel in each subsequent hour. This means that, at a constant rate of fuel burn of 4000 lbs per hour, the Electra can fly for a further three hours after the first hour, for a total endurance of four hours.
The Electra's fuel burn rate and endurance are important considerations for its operators, as they impact the aircraft's range and operational capabilities.

The Electra's fuel burn decreases by 200 lbs per hour
The Lockheed L-188 Electra is a large turboprop airliner with a high power-to-weight ratio, huge propellers, and very short wings. It was the first aircraft of its kind to be built in the United States, first flown in 1957.
The Electra has a fuel burn of 5,000 lbs for the first hour and 4,000 lbs for each hour after that, according to one source. Another source states that the fuel burn starts at 5,000 lbs per hour and decreases by 200 lbs per hour thereafter, with an endurance of up to 9 hours. This means that the fuel burn for the second hour is 4,800 lbs, for the third hour it is 4,600 lbs, and so on.
The Electra's fuel burn is affected by its weight. The maximum takeoff weight of the Electra is 116,000 lbs, and the maximum payload is generally considered to be 32,000 lbs. The aircraft can also carry nearly 40,000 lbs of cargo.
The fuel burn of the Electra is also influenced by the type of mission it is used for. For example, the Argentine Navy modified several Electra airframes for maritime patrol, and these aircraft had a higher fuel capacity than the civilian version.
Overall, the Electra's fuel burn decreasing by 200 lbs per hour allows for efficient long-duration flights, with the ability to carry significant payloads.

The Electra has a fuel capacity of 6,940 US gallons
The Lockheed L-188 Electra is a large turboprop airliner with a fuel capacity of 6,940 US gallons (26,300 litres). It is powered by four wing-mounted Allison 501-D13 turboprops, giving it a high power-to-weight ratio. The Electra's fuel capacity allows for a long range, and it has been used for various roles, including cargo transport, aerial firefighting, and passenger flights.
The fuel burn rate of the Lockheed L-188 Electra varies depending on the phase of flight and the weight of the aircraft. During climb, the aircraft can burn approximately 100 pounds of fuel per minute. In cruise, with a maximum take-off weight of 116,000 pounds, the fuel burn starts at 5,000 pounds per hour and decreases by approximately 200 pounds for each subsequent hour of flight.
With a typical load, the fuel burn is 5,000 pounds for the first hour and 4,000 pounds for each additional hour. This allows the aircraft to carry a substantial payload, with a maximum payload of around 32,000 pounds. The Electra's fuel capacity and burn rate give it an endurance of up to 9 hours, depending on weight and flight conditions.
The Electra's fuel efficiency and range have contributed to its versatility and longevity. Despite being first flown in 1957, some Electras are still in use today, serving in cargo, firefighting, and other specialised roles.

The Electra is a turboprop airliner with a four-engined design
The Lockheed L-188 Electra is an American turboprop airliner with a four-engined design. It was first flown in 1957 and was the first large turboprop airliner built in the United States. The Electra has a high power-to-weight ratio, huge propellers, and very short wings, resulting in exceptional airfield performance capabilities, particularly on short runways and high-altitude airfields.
The Electra's four-engined design sets it apart from other aircraft and contributes to its impressive performance. Each engine plays a crucial role in providing the necessary thrust and power to propel the aircraft forward.
The fuel consumption of the Lockheed Electra varies depending on the phase of flight and the weight of the aircraft. During the climb phase, the Electra can burn approximately 100 pounds of fuel per minute. This translates to a fuel burn rate of around 6000 pounds per hour during the initial climb.
Once the aircraft reaches its cruising altitude, the fuel burn rate decreases. With a maximum take-off weight of 116,000 pounds, the Electra's fuel burn starts at 5000 pounds per hour during the cruise and decreases by approximately 200 pounds for each subsequent flying hour. This means that during the second hour of cruise, the fuel burn would be around 4800 pounds per hour, and during the third hour, it would be approximately 4600 pounds per hour, and so on.
The fuel consumption figures can also be affected by other factors such as the payload and the operating weight of the aircraft. The maximum payload of the Electra is generally considered to be around 32,000 pounds. By balancing the payload and fuel load, the aircraft can achieve a normal cruise endurance of up to seven hours.
