What You'll Learn
The PA28R 200 Arrow II fuel capacity is 77 USG
The PA28R 200 Arrow II has a total fuel capacity of 77 US gallons (USG). This is an important detail to note for pilots, as it directly impacts the plane's range and performance.
The fuel capacity of an aircraft is the maximum amount of fuel that can be safely carried on board. It is essential to know the fuel capacity and the rate at which the aircraft burns fuel to plan refuelling stops and ensure the plane has sufficient range to reach its destination.
The PA28R 200 Arrow II burns fuel at different rates depending on the power setting. According to the Piper Arrow II information manual, at 75% power, the fuel burn rate is 10.15 gallons per hour (gph), while at 65% power, it burns 9.16 gph, and at 55% power, the burn rate is 8.0 gph. These values are approximate and assume proper mixture control.
It's worth noting that the usable fuel capacity may be slightly less than the total capacity due to fuel that cannot be accessed or used by the aircraft's systems. In the case of the PA28R Arrow III, for example, the total fuel capacity is 77 USG, but 5 USG are listed as unusable, leaving a usable capacity of 72 USG. This information can typically be found in the pilot's operating handbook or flight manual, though it may also be placarded near the filler caps.

5 USG of fuel in the PA28R 200 is unusable
The PA28R 200 aircraft has a total fuel capacity of 77 US gallons, with 5 US gallons considered unusable. This means that only 72 US gallons of fuel in the aircraft can be utilized during flight.
It is important to distinguish between the total fuel capacity of an aircraft and the amount of fuel that is usable. The unusable fuel amount may vary between different models and versions of the PA28 aircraft. For example, some pilots and owners of the PA28-160 model have reported a usable fuel figure of 48 US gallons, while others have suggested that the FAA-approved usable fuel amount after practical tests is 49.6 US gallons.
The discrepancy in the usable fuel amount can be attributed to various factors, including the aircraft's weight and balance, as well as the method used to measure the usable fuel. For instance, the usable fuel quantity may differ when the aircraft is sitting on the apron (on the ground) compared to when it is in flight at variable attitudes.
Additionally, proper fuel management practices, such as regularly checking fuel tanks and leaning the mixture on long trips, can impact the usable fuel amount. Some pilots recommend flying with full tanks if airfield performance and mass and balance allow, as this can provide a longer endurance of approximately 4.5 hours.
Furthermore, fuel burn rates can vary between different airframes of the PA28, ranging from 8.5 to 10 US gallons per hour. Thus, it is essential to consider the specific characteristics and performance of the PA28R 200 aircraft when determining the impact of 5 US gallons of unusable fuel.

The Piper Arrow II manual provides fuel burn rates
According to a user on PPRuNe Forums, they typically cruise at 65% power and reckon "on just under 10 US gallons or 38 litres per hour". At 75% power, they note that while more fuel is burned, there isn't a significant increase in airspeed.
Regarding the fuel capacity of the PA28R-201, one source mentions the PA28R Arrow III, which has a total fuel capacity of 77 US gallons (USG), with 5 unusable. For the PA28R Arrow II, the capacity is 14 imperial gallons per side and 21 imperial gallons to full, resulting in a difference of 7 imperial gallons per side or approximately 63 litres. However, another source mentions a best range of 695 NM and a fuel burn rate of 11.6 GPH, without specifying the power percentage.

The PA28R 200 burns 10 USG per hour at 65% power
The PA28R 200 Arrow II is a powerful aircraft with a fuel capacity of 77 US gallons or 63 litres in total. This includes 5 gallons that are typically deemed unusable.
When it comes to fuel burn, the PA28R 200 has impressive efficiency. According to the Piper Arrow II information manual, at 65% power, the aircraft burns approximately 9.16 US gallons per hour. In practice, pilots often report a slightly higher fuel burn of just under 10 US gallons or 38 litres per hour when cruising at 65% power. This small discrepancy between the manual and real-world experience is worth noting for pilots planning their fuel needs.
Cruising at 65% power is a common practice for pilots of the PA28R 200. This setting strikes a balance between fuel efficiency and performance, allowing pilots to maintain a good airspeed without burning through fuel too quickly. At this setting, the aircraft can cover significant distances while still having a respectable endurance.
It is important to note that fuel burn rates can be influenced by various factors, including altitude, temperature, and headwinds or tailwinds. Additionally, proper leaning techniques are essential to achieving optimal fuel efficiency. By leaning the mixture correctly, pilots can ensure that the engine is running at its most efficient state, extracting the maximum energy from each gallon of fuel burned.
In conclusion, the PA28R 200's fuel burn of 10 US gallons per hour at 65% power showcases its efficiency and performance capabilities. This information is crucial for pilots when planning their fuel requirements, especially considering the small difference in burn rates between cruising at 65% and 75% power. Understanding these nuances can significantly impact the overall range and endurance of the aircraft during flight operations.

At 75% power, the burn rate is 10.15 gallons per hour
The PA28R 200 Arrow II, fitted with an IO-360-CIC engine, has a fuel capacity of 77 US gallons, with 5 gallons being unusable. At 75% power, the burn rate is 10.15 gallons per hour. This burn rate is an important factor to consider when planning flights, as it directly impacts the aircraft's range and endurance.
To elaborate, the PA28R 200's fuel burn rate at 75% power provides insight into its fuel efficiency at this particular power setting. A burn rate of 10.15 gallons per hour means that, at 75% power, the aircraft consumes fuel at a rate of 10.15 gallons for every hour of flight. This information is crucial for pilots and flight planners, as it helps determine the aircraft's range, or how far it can fly before needing to refuel. By dividing the total usable fuel capacity by the burn rate at 75% power, we can estimate the aircraft's maximum range at this power setting.
Additionally, the burn rate impacts the aircraft's endurance, which is the amount of time it can remain airborne before needing to refuel. At 75% power, the PA28R 200's endurance is inversely proportional to the burn rate. In other words, a higher burn rate results in a shorter endurance, assuming all other factors remain constant. Therefore, understanding the burn rate at different power settings allows pilots to make informed decisions about power settings, fuel usage, and the overall endurance of the aircraft during flight.
It is worth noting that the burn rate provided assumes proper leaning of the fuel mixture. Leaning the mixture involves adjusting the air-fuel ratio to ensure efficient combustion, and incorrect leaning can lead to higher fuel consumption. Additionally, environmental factors such as temperature, pressure altitude, and headwinds can also impact the actual fuel burn rate during a flight. Therefore, the provided burn rate of 10.15 gallons per hour at 75% power serves as an estimate or average value, and the actual fuel usage may vary depending on various factors and flight conditions encountered.
In summary, the PA28R 200 Arrow II's fuel burn rate of 10.15 gallons per hour at 75% power is a critical piece of information for flight planning and performance calculations. It influences the aircraft's range and endurance, providing pilots and operators with valuable data to make informed decisions regarding fuel usage, flight routes, and overall flight efficiency. Understanding the relationship between power settings and fuel burn rates is essential for optimizing the aircraft's performance and ensuring safe and efficient operations.
