Arrival Final 1

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 in question took off from runway 24 at the 4N1 Greenwood Lake airport in a Piper PA-24-250 Comanche. The departure roll was smooth, and it covered 289 meters, which is approximately 27 percent of the total runway length. During takeoff, the liftoff speed was reached at 70 knots.

After a successful takeoff, the flight continued on a climb trajectory, starting from an altitude of 1,656 feet above sea level and increasing to 1,858 feet above sea level, which is a gain of 201 feet in less than one minute. The aircraft covered a distance of less than one nautical mile during this time.

Once the enroute climb was completed, the aircraft leveled off into a cruise phase, starting from a point one mile south of West Milford, New Jersey. During this phase, which lasted for three minutes, the aircraft covered a distance of three nautical miles.

The final approach to runway 24 at 4N1 Greenwood Lake was carried out from the northeast, heading 208.0 degrees at an altitude of 312 feet above ground level and at a distance of one nautical mile from the threshold. The aircraft landed smoothly on the runway, with a touchdown speed of 44 knots, which was within the target range.

The landing distance was good at 349 meters, which represents 46 percent of the total runway length. The runway touchdown alignment was very good. Post-landing, during the taxiing phase, the aircraft deviated slightly from the centerline by 7.7 meters.

After landing, the aircraft taxied to the parking area from the runway in less than one minute, covering a short distance of less than one nautical mile. Over the course of the flight, the aircraft used 3 kilograms of fuel, and the total flight distance was 5 nautical miles, which took approximately six minutes to complete.

Landing Score 87.78 %
Landing Summary

The landing of the Piper PA-24-250 Comanche at 4N1 Greenwood Lake airfield was a successful event, with the aircraft scoring 87.8% in its performance review. The aircraft approached the runway from the northeast, aligning itself with the 208.0° heading as it descended to 312 feet above ground level and 1 nautical mile from the runway. The final approach to runway 24 was executed smoothly and efficiently.

Upon touching down on the runway, the aircraft displayed a satisfactory performance. The threshold height was good, and although the threshold speed of 61 knots was slightly below the target, it still allowed for a controlled touchdown. The touchdown distance of 349 meters was also commensurate with the runway's length, indicating a reasonable deceleration during the landing sequence. Moreover, the touchdown speed of 44 knots and the touchdown rate of -187 feet per minute were both within acceptable limits.

The alignment of the aircraft with the runway during touchdown was excellent, but the situation worsened during the rollout. Although the total landing distance of 483 meters was somewhat reduced compared to the available runway length, accounting for only 46% of the runway, the rollout alignment was slightly off-center by about 7.7 meters.

Weather conditions on the day of the landing were mild, with a temperature of 24°C and light winds blowing at 4 knots from a direction of 90°. The crosswind, tailwind, and headwind components were very minimal, which might have contributed to the relatively efficient touchdown and landing performance of the aircraft.
