What You'll Learn
A Boeing 737-800 burns 3,200 litres of jet fuel per hour
A Boeing 737-800 aircraft burns 3,200 litres of jet fuel per hour, or 5,500-6,600 pounds, according to one source. This makes it a relatively fuel-efficient aircraft, especially when compared to larger planes such as the Boeing 747-400, which burns around 10-11 tons (22,000-24,000 pounds) of jet fuel per hour.
The 737-800 is the most common variant of the 737NG (Next Generation) family. It is used by airlines such as Ryanair, which operates routes across Europe, the Middle East, and North Africa.
Fuel consumption rates for commercial jet airliners vary depending on the type of aircraft and the duration of the flight. For example, shorter flights using a 737-800 will burn less fuel per hour than a longer flight. Other factors that can affect fuel consumption include altitude, winds, and routing.
In addition to traditional jet fuel, the 737-800 can also be powered by a blend of algae-derived biofuel and jet fuel, as demonstrated on a United Airlines flight from Houston to Chicago in 2011. This blend helps to reduce the aircraft's carbon footprint.

Fuel usage depends on aircraft type and flight duration
Fuel usage depends on several factors, including aircraft type and flight duration. A Boeing 747-400, for instance, burns approximately 10-11 tons (22,000-24,000 pounds) of jet fuel per hour. In contrast, a shorter flight using a Boeing 737-800, which is the most common variant of the 737NG (Next Generation) family, consumes about 2.5-3 tons (5,500-6,600 pounds) of fuel per hour.
The fuel efficiency of an aircraft is influenced by various factors, such as the aircraft's weight, altitude, winds, and routing. A heavier aircraft requires more fuel to generate the necessary lift and thrust for takeoff and cruise. Additionally, flying at higher altitudes can result in lower air density, impacting fuel consumption.
Wind conditions can significantly affect fuel efficiency. Strong headwinds can increase fuel consumption as the aircraft needs more power to maintain speed and altitude. On the other hand, tailwinds can reduce fuel consumption by decreasing the time required to reach the destination.
The chosen route can also impact fuel usage. A more direct route may be preferable to reduce flight time and fuel consumption. However, in certain cases, such as taking advantage of strong jet streams during winter, a less direct route might be more fuel-efficient despite the longer distance.
Different aircraft types also have varying fuel capacities and consumption rates. For example, the Airbus A320 typically burns around 2.5 tons of fuel per hour, while the Boeing 777 consumes about 7-8 tons per hour. The Airbus A380, a large aircraft, has a maximum fuel capacity of 500,000 pounds, showcasing the variation in fuel requirements across different models.

A 737 burns 6,000 pounds of fuel per hour
A 737 aircraft burns through a significant amount of fuel during ground and flight operations. While on the ground, various factors influence fuel consumption, and it is challenging to provide an exact figure for the hourly fuel burn. However, we can examine the overall fuel usage and average burn rate to gain insights.
The 737-800 variant, commonly used by airlines such as Ryanair, is a notable example. This aircraft burns approximately 850 US gallons (3,200 liters) of jet fuel per hour. When considering a shorter flight, the fuel burn rate is approximately 2.5-3 tons (5,500-6,600 pounds) per hour. This aligns with the perspective of a pilot who shared their experience, stating that their mental calculation for the 737 is around 6,000 pounds per hour (PPH).
This burn rate of 6,000 pounds per hour translates to approximately 1490 gallons per hour. It is worth noting that factors like altitude, winds, and routing can impact fuel consumption. However, efficient routing is typically considered by dispatch to optimize fuel usage.
The fuel burn rate of 6,000 pounds per hour provides a reasonable estimate for the 737's fuel usage on the ground and during shorter flights. It is important to acknowledge that fuel consumption can vary based on specific flight conditions and aircraft variants within the 737 family. Nevertheless, this burn rate offers a practical perspective on the aircraft's fuel efficiency and operational considerations.

A 737 uses 2.5-3 tons of fuel per hour
The amount of fuel burned by a 737 on the ground depends on several factors, including the variant of the aircraft, the weight of the aircraft, the duration of ground operations, and the specific operating procedures of the airline and airport.
The Boeing 737-800, the most common variant of the 737NG (Next Generation) family, burns approximately 850 US gallons (3,200 liters) of jet fuel per hour. This translates to about 2.5-3 tons (5,500-6,600 pounds) of fuel per hour. However, the actual fuel consumption can vary depending on various factors, such as the weight of the aircraft, the altitude, winds, and routing.
During ground operations, the engines of a 737 may be running for activities such as taxiing, pre-flight checks, or auxiliary power unit (APU) operations. The fuel consumption during these ground operations can vary depending on the duration and the specific procedures followed by the airline and airport.
It's important to note that fuel consumption rates can also be affected by factors such as aircraft maintenance, engine efficiency, and operating conditions. Airlines and aircraft operators may employ various strategies to optimize fuel efficiency, including routing optimizations and the use of fuel-efficient procedures.
In summary, a 737 typically consumes approximately 2.5-3 tons of fuel per hour, but the actual fuel usage on the ground can vary depending on various factors related to the specific aircraft, operating procedures, and environmental conditions.

Fuel burn rate can be calculated by measuring fuel burnt and converting to per hour
The fuel burn rate of an aircraft can be calculated by measuring the fuel burnt during different stages of a flight and converting it to a per-hour burn rate. This can be done by measuring the fuel used from start-up to take-off, climb to altitude, gliding back to landing, and then calculating the average fuel burn per hour.
For example, a Boeing 737-800 burns 850 US gallons (3,200 litres) of jet fuel per hour. On a flight from BWI to LAS, a 737 burned about 30,000 pounds of fuel in just under five hours, averaging about 6,000 pounds per hour (PPH). This burn rate can be influenced by factors such as altitude, winds, and routing, but dispatch typically aims for the most efficient route.
In comparison, smaller propeller planes like the Cessna 172 and 182 burn less fuel, at 8 gallons and 12 gallons per hour, respectively, while flying at lower speeds of 105 mph and 120 mph.
Additionally, the fuel burn rate can vary depending on the stage of the flight. For instance, a 777 FO long-haul flight may require about 4,400 pounds per hour during take-off and 1,800-1,900 pounds per hour during cruise, with an average flight fuel load of 10,000-12,000 pounds of fuel.
By measuring the fuel burnt during specific flight segments and calculating the average burn rate per hour, pilots and operators can gain insights into fuel efficiency and make informed decisions about routing and fuel load for subsequent flights.
