What is the AvGas consumption for a climb to 12,000 feet for an aircraft weighing 3,700 lb at sea level?

To determine the AvGas consumption during a climb to 12,000 feet, it's important to consider the aircraft’s weight, the climb rate, and fuel consumption rates generally associated with that altitude and aircraft performance.

In this case, if the aircraft weighs 3,700 pounds at sea level and is climbing to 12,000 feet, we can use typical fuel consumption rates for similar aircraft in a climb phase. While the specific fuel consumption can vary based on the engine type and conditions, general approximations can be used for estimation.

Assuming the aircraft has a reasonable fuel burn rate during climb—which for many light general aviation aircraft is around 10 to 15 gallons per hour—the estimate of 10 gallons for a climb to 12,000 feet becomes a reasonable choice. This fits within the expected fuel consumption during a typical climb operation, which can be around 1 gallon per 1,000 feet climbed in some cases but can vary based on many operational factors.

Therefore, identifying 10 gallons as the likely consumption appears sound based on common fuel burn patterns in climb scenarios for similarly weighted aircraft.
