The Hughes XF-11 aircraft began its taxiing process from the parking area to the runway, taking approximately 2 minutes to cover less than 1 nautical mile. This marked the start of its departure from San Diego International Airport, where it took off from runway 27. The takeoff distance covered 43% of the runway, amounting to 2,987 feet. The aircraft lifted off at a speed of 170 knots.
The local weather conditions at the time of takeoff were characterized by a temperature of 71 degrees Fahrenheit and a wind speed of 10 knots from a direction of 260 degrees. This resulted in a crosswind of 4 knots and a headwind of 9 knots. The aircraft then began its enroute climb, starting from an altitude of 1,028 feet above sea level and ascending to 98 feet above sea level, an increase of 930 feet in just 2 minutes. This climb covered a distance of 3 nautical miles.
After completing its climb, the Hughes XF-11 aircraft prepared for landing at North Island Naval Air Station-Halsey Field, where it touched down on runway 29. The runway had a length of 7,502 feet, and the threshold height at 58 feet above ground level was slightly above the target. The threshold speed was good at 133 knots, and the touchdown distance was also satisfactory at 976 feet. The touchdown speed was 106 knots, which was within the acceptable range.
However, the touchdown rate was heavy at -612 feet per minute, indicating a steeper descent than intended. The runway touchdown position was slightly misaligned from the centerline by 17 feet. The local weather conditions at the time of landing were characterized by a temperature of 68 degrees Fahrenheit and a wind speed of 10 knots from a direction of 259 degrees, resulting in a crosswind of 7 knots and a headwind of 7 knots.
The total landing distance covered 32% of the runway, amounting to 2,391 feet. The runway rollout alignment was very good, indicating that the aircraft maintained its stability and control during the landing process. The total flight distance was 5 nautical miles, and the flight duration was 4 minutes. The aircraft used a total of 148 pounds of fuel during the flight.

The Hughes XF-11 aircraft successfully landed on runway 29 at KNZY North Island Naval Air Station-Halsey Field, showcasing a commendable performance. The aircraft's touchdown distance of 976 feet was within acceptable limits, indicating a well-executed approach. The touchdown speed of 106 knots was also satisfactory, demonstrating the pilot's ability to control the aircraft's descent.
However, the touchdown rate of -612 feet per minute was slightly heavy, suggesting that the pilot may have applied a bit too much braking or reverse thrust upon touchdown. This could be a minor concern, but it did not appear to have any significant impact on the overall landing performance.
The runway touchdown position was slightly misaligned by 17 feet from the centerline, which may require some adjustments to the pilot's approach and landing technique. Nevertheless, the runway rollout alignment was very good, indicating that the pilot was able to maintain control of the aircraft during the rollout phase.
The local weather conditions were favorable, with a temperature of 68°F and a moderate headwind of 7 knots. The wind direction was from 259°, which was not directly perpendicular to the runway, but the crosswind component was relatively low at 7 knots. Overall, the landing performance of the Hughes XF-11 aircraft was satisfactory, with some minor areas for improvement.
