This flight was conducted using a Curtiss JN-4D aircraft, a biplane designed for training and recreational purposes. The flight began with an enroute climb from a starting point 1 mile west of Ploiesti, Romania, where the aircraft lifted off from an altitude of 767 feet above sea level. However, the climb was not significant, with the aircraft only maintaining the same altitude for the duration of the climb, which lasted for 1 minute and covered less than 1 nautical mile.

Following the climb, the aircraft entered an enroute level cruise phase, which started 1 mile west of Ploiesti and lasted for 69 minutes. During this period, the aircraft covered a distance of 48 nautical miles. The cruise phase was followed by an enroute descent, which began overhead Paulesti, Romania. The descent was from an altitude of 1,975 feet above sea level to 1,506 feet, a decrease of 469 feet in just 2 minutes, covering a distance of 2 nautical miles.

The aircraft then entered another enroute level cruise phase, which started 1 mile north-west of Ploiesti and lasted for 4 minutes. This phase covered a distance of 4 nautical miles. The final approach to runway 27 at LRPW Gheorghe Valentin Bibescu was made from the east, with the aircraft heading 277.0 degrees at an altitude of 328 feet above ground level and a distance of 1 nautical mile from the runway.

The landing on runway 27 was conducted with a runway length of 938 meters. The threshold height was good, but the threshold speed was excessively high at 63 knots. The touchdown distance was good at 355 meters, but the touchdown speed was excessively fast at 56 knots. The touchdown rate was fair at -296 feet per minute. The runway touchdown position was slightly misaligned by 4.0 meters from the centreline.

The local weather conditions during the flight were characterized by a temperature of 15 degrees Celsius, with a wind speed of 1 knot from 270 degrees. There was no crosswind, but a headwind of 1 knot was present. The total flight distance was 54 nautical miles, and the flight duration was 53 minutes. The aircraft used 29 kilograms of fuel during the flight.

Landing Score 70.58 %

Landing Summary

The Curtiss JN-4D aircraft successfully landed on runway 27 at LRPW Gheorghe Valentin Bibescu, but with some notable areas for improvement. The final approach was initiated from the east, heading 277.0° at 1 nautical mile and 328 feet above ground level (agl). The aircraft touched down on the runway, which has a length of 938 meters.

The threshold height was satisfactory, but the threshold speed was excessively high at 63 knots. This indicates that the pilot may have been able to slow down more efficiently before touchdown. The touchdown distance of 355 meters was good, suggesting that the pilot had sufficient control over the aircraft's descent. However, the touchdown speed of 56 knots was excessively fast, which may have put additional stress on the aircraft's landing gear.

The touchdown rate of -296 feet per minute (fpm) was fair, indicating that the pilot had some control over the aircraft's descent rate. However, the runway touchdown position was slightly misaligned by 4.0 meters from the centerline, which may have been due to a slight deviation in the pilot's approach path.

The local weather conditions at the time of the landing were relatively calm, with a temperature of 15°C and a wind speed of 1 knot from 270°. There was no crosswind, but a slight headwind of 1 knot was present. These conditions would have made the landing relatively straightforward, but the pilot's performance could still be improved upon. Overall, the landing was satisfactory, but there is room for improvement in terms of speed control and alignment.
