Arrival Final 2

Preparing for a stable approach will give you time to decide on whether to attempt the landing or going around. Too much altitude with a high sink rate will result in carrying too much speed onto the runway. Configuring flaps and the gear late also won't help the speed decay.

Flight narrative

The flight began with a departure roll from runway 24 at 4N1 Greenwood Lake. The aircraft, a Cessna C152, accelerated down the runway and lifted off at a speed of 58 kt, covering a distance of 58 m, which was 5% of the runway length. The local weather conditions at the time of takeoff were characterized by a temperature of 14 °C and a wind speed of 2 kt from a direction of 320 °, resulting in a negligible crosswind and headwind.

As the aircraft climbed away from the airport, it began its enroute climb, which started overhead West Milford, New Jersey. The climb was initiated from an altitude of 1,208 ft above sea level and continued to an altitude of 1,700 ft, an increase of 491 ft, in just 1 minute. During this time, the aircraft covered a distance of 1 nm. Following the climb, the aircraft entered a level cruise phase, which lasted for 2 minutes and covered a distance of 2 nm. This phase was initiated 1 mile southeast of West Milford.

The enroute descent phase began 1 mile east of 4N1 Greenwood Lake, West Milford, and involved a descent from an altitude of 2,124 ft above sea level to 1,350 ft, a decrease of 774 ft, in 2 minutes. The aircraft covered a distance of 1 nm during this phase. The final approach to runway 24 at 4N1 Greenwood Lake was initiated from the north-east, with the aircraft heading 228.0 ° at an altitude of 550 ft above ground level and a distance of 1 nm from the runway threshold.

The landing was made on runway 24, which had a length of 1,053 m. The threshold height was good, but the threshold speed was excessively high at 73 kt. The touchdown distance was good at 360 m, but the touchdown speed of 55 kt was fast. The touchdown rate was good at -160 fpm. However, the runway touchdown position was slightly misaligned from the centreline by 3.8 m. The local weather conditions at the time of landing were the same as those at the time of takeoff, with a temperature of 14 °C and a wind speed of 2 kt from a direction of 320 °, resulting in a negligible crosswind and headwind.

In summary, the flight was a short one, covering a total distance of 6 nm in 5 minutes, and using 1 kg of fuel. The aircraft performed well throughout the flight, with a good climb and descent profile, and a smooth landing. However, there were some minor issues with the threshold speed and touchdown speed, which were slightly higher than desired.

Landing report
Landing on runway 24 at 4N1 Greenwood Lake in the Cessna 152
Landing Score 91.77 %
Landing Summary

The Cessna C152 aircraft successfully landed at 4N1 Greenwood Lake, achieving a score of 91.8%. The final approach was conducted from the north-east, heading 228.0° at 1 nautical mile and 550 feet above ground level (agl). The aircraft's approach to the runway was precise, with a good threshold height, indicating that the pilot maintained a suitable altitude before touching down.

However, there were some areas for improvement during the landing. The threshold speed was excessively high at 73 knots, which is above the recommended speed for a safe landing. This could have been due to the pilot's experience or the aircraft's performance characteristics. Despite this, the touchdown distance was good at 360 meters, indicating that the pilot maintained control of the aircraft during the landing.

The touchdown speed of 55 knots was also faster than recommended, which could have put additional stress on the aircraft's landing gear and potentially affected the overall safety of the landing. On the other hand, the touchdown rate of -160 feet per minute (fpm) was good, indicating that the pilot managed to slow the aircraft down quickly and smoothly after touchdown.

The runway touchdown position was slightly misaligned by 3.8 meters from the centreline, which could have been due to a slight deviation in the pilot's approach or a minor issue with the aircraft's navigation system. However, this did not appear to have any significant impact on the safety of the landing.

The local weather conditions at the time of the landing were relatively calm, with a temperature of 14°C and a wind speed of 2 knots from 320°. This meant that there was a slight crosswind component, but it was not strong enough to significantly affect the landing. Overall, the pilot demonstrated good skills and control during the landing, but there were some areas for improvement that could be addressed in future flights.
