The endurance of a Cessna depends on the specific model and its fuel tank configuration, but for the ubiquitous Cessna 172 Skyhawk, the standard flight time is approximately 4 to 5 hours without refueling. This assumes a standard fuel capacity of 53 gallons (56 for newer models) and a typical burn rate of about 8 to 10 gallons per hour at 75% power. In terms of distance, this translates to roughly 500 to 650 nautical miles (about 575 to 750 miles) depending on the wind conditions. However, pilots are legally required to land with at least 30 minutes of "reserve" fuel (45 minutes at night), which practically reduces the safe range to about 4 hours. Some specialized "long-range" variants with auxiliary tanks can fly for over 6 hours. Interestingly, the world record for Cessna endurance was set in 1958 by a Cessna 172 that stayed airborne for 64 days, 22 hours, and 19 minutes; however, this was achieved by refueling from a moving truck on a runway, proving that while the pilot's stamina has limits, the airframe itself is remarkably durable.
