Flight Score
Departure
Ease the nose up sooner to lift off at 35 kt instead of letting speed build on the ground.
What happened: The aircraft lifted off at 48 kt, 13 kt above the target liftoff speed.
Watch for: Airspeed indicator: 35 kt at liftoff
See Departure Roll
Arrival
Raise the nose more slowly in the flare and stop as soon as the sink is checked; if it balloons, hold the attitude.
What happened: The flare ballooned, with 161 fpm of sink returning after the arrest; a balloon like this usually carries through to a firm touchdown, as it did here at 285 fpm.
Watch for: The runway ahead: the aircraft still sinking gently towards it through the flare, never rising.
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.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: seven checks where the approach path is 300 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out. These checks are the approach's score.
At the 300 ft gate: no landing flap set and centreline 6.3° off, against a 1° limit.
The approach, gate by gate
three-point landing
Side view — the last 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 11,234 ft runway, to the same scale as the side view.
The 61 ft touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Curtiss JN-4D taxied to runway 33 at KPNE Northeast Philadelphia Airport and commenced the departure roll, achieving a takeoff distance of 1,111 ft (22 % of the runway) and lifting off at 48 kt. Ambient conditions were a temperature of 60 °F, wind 2 kt from 270°, with a 1 kt cross-wind component and a 1 kt head-wind component.
After departure, the aircraft entered a level cruise segment that began overhead KPNE and continued for 23 minutes, covering a distance of 26 nm.
The first descent phase started when the aircraft passed overhead Princeton Meadows, New Jersey, descending from 2,107 ft asl to 1,585 ft asl - a loss of 522 ft - over a period of 2 minutes while traveling 2 nm.
Subsequently, a second level cruise commenced approximately 1 mile north of Cranbury, New Jersey, lasting 32 minutes and encompassing 38 nm of flight.
The next descent began over Broad Channel, New York, with the aircraft dropping from 1,390 ft asl to 195 ft asl, a reduction of 1,194 ft in 2 minutes and covering 3 nm.
For the final approach to runway 31L at KJFK John F. Kennedy International Airport, the aircraft descended from 269 ft agl to 18 ft agl in 65 seconds and was recorded as having scored on the stabilisation gates.
Landing on runway 31L was completed with a runway length of 11,234 ft; the threshold speed was 41 kt, touchdown distance measured 51 ft, touchdown speed was 40 kt, and the vertical speed at touchdown was minus 268 fpm. Runway touchdown alignment was very good, and local weather reported a temperature of 59 °F, wind 2 kt from 270°, with a 1 kt cross-wind and a 1 kt head-wind component. The total landing distance recorded was 440 ft (4 % of the runway), and rollout alignment was very good.
During rollout the aircraft traveled the 440 ft landing distance while maintaining excellent alignment with the runway centreline.
In total, the flight covered 70 nm, required 61 minutes of elapsed time, and consumed 54 lb of fuel.
The Curtiss JN-4D completed its final approach to runway 31L at KJFK, descending from 269 ft agl to 18 ft agl in 65 seconds and receiving a score on the stabilisation gates.
At threshold the aircraft maintained a good height and a good threshold speed of 41 kt. Touchdown distance was good at 51 ft, while touchdown speed of 40 kt was noted as a little fast. The touchdown rate was fair at minus 268 fpm and runway touchdown alignment was very good; ambient conditions were 59 °F with a 2-kt wind from 270°, including a 1-kt crosswind and a 1-kt headwind.
Touchdown occurred 51 ft beyond the threshold at a speed of 40 kt, a descent rate of minus 268 fpm, and with very good alignment to the runway centreline.
Rollout covered a total landing distance of 440 ft, representing 4 % of the 11,234-ft runway, and runway rollout alignment remained very good.
To refine the already strong performance, the pilot should aim to reduce touchdown speed slightly toward the target VREF and adjust the flare to achieve a gentler descent rate, which will further improve touchdown quality while preserving the excellent alignment already demonstrated.
