What went well

Straight touchdown — 1.2 ft off the centreline, no bounce
1.06 G at touchdown — inside band
Airborne in 1,050 ft — 21 % of the runway

What held you back

Enroute Descent — overspeed warning, then stall warning; speed limits at 0 %, g force 0.27 to 4.45 g at 0 %, −2.90 points
Arrival Touchdown — Touchdown VSI was -445 fpm. at 12 %, bank angle up to 6.3 ° at 46 %, −2.57 points
Arrival Final 2 — speed limits at 0 %, −2.53 points
Arrival Landing — Flare profile at 39 %, −1.36 points

Top opportunity

Work on the flare

Arrival Landing

Arrive slow and the sink rate at the threshold is already above schedule, the flare is short because there is no energy to extend it, and the touchdown is hard in a way that feels exactly like a late flare. Diagnosing a slow arrival as a late flare is the catastrophic misread: you respond by flaring earlier, which bleeds more speed, which makes the next one worse. The tiebreaker is threshold speed against VRef, not feel. Never diagnose a flare without it.

Flight narrative

The Curtiss JN-4D taxied to runway 33 at KPNE Northeast Philadelphia Airport and commenced the departure roll, covering a takeoff distance of 1,050 ft (21 % of the runway) before lifting off at 49 kt. Ambient conditions were 60 °F with a wind of 2 kt from 269°, including a 1 kt cross-wind component and a 1 kt head-wind component.

After liftoff the aircraft entered the climb phase overhead KPNE, ascending from 505 ft asl to 1,210 ft asl - a gain of 704 ft - in 2 minutes while traversing 2 nm.

The first cruise segment began 1 nm west of Bensalem, Pennsylvania, and persisted for 2 minutes, during which the aircraft covered 2 nm at level flight.

A descent commenced overhead Eddington, Pennsylvania, lowering the altitude from 1,503 ft asl to 971 ft asl - a loss of 532 ft - in 2 minutes and spanning 2 nm.

The next cruise interval started over Croydon, Pennsylvania, lasting 26 minutes and encompassing 29 nm of level flight.

Subsequent descent activity began 3 nm west of Lakewood, New Jersey, reducing altitude from 3,637 ft asl to 3,039 ft asl - a decrease of 598 ft - in 2 minutes while covering 2 nm.

A brief cruise followed 1 nm west of Lakewood, lasting 2 minutes and adding another 2 nm to the flight path.

The aircraft then descended from a point 1 nm north-east of Lakewood, dropping from 3,258 ft asl to 1,005 ft asl - a loss of 2,253 ft - in 2 minutes over a distance of 1 nm.

A longer cruise segment originated again 1 nm north-east of Lakewood, extending for 36 minutes and covering 40 nm at constant altitude.

The final descent started overhead Edgemere, New York, where altitude fell from 2,061 ft asl to 498 ft asl - a reduction of 1,563 ft - in 2 minutes across 2 nm.

The aircraft entered the final approach to runway 31L at KJFK John F. Kennedy International Airport from the south-east, on a heading of 300.0°, positioned 2 nm out and 484 ft agl.

Landing was executed on runway 31L, whose length is 11,234 ft. The threshold height was good and the threshold speed was slightly above the target at 43 kt. Touchdown occurred 1,278 ft down the runway at a speed of 40 kt, with a hard touchdown rate of minus 445 fpm, and the aircraft aligned perfectly with the centreline. Local weather at the time was 59 °F with a wind of 2 kt from 270°, including a 1 kt cross-wind and a 1 kt head-wind component.

In total the flight covered 83 nm, required 76 minutes of elapsed time, and consumed 64 lb of fuel.

Landing Summary

The Curtiss JN-4D entered the final approach to runway 31L at KJFK from the southeast, tracking a heading of 300.0° at 2 NM and 484 ft AGL. Local conditions were 59 °F with a wind of 2 kt from 270°, including a 1-kt crosswind component and a 1-kt headwind component.

At the threshold the aircraft encountered a good threshold height and the runway length was 11,234 ft. The threshold speed was slightly above target at 43 kt.

Touchdown occurred 1,278 ft down the runway, a distance described as good. Touchdown speed was 40 kt, noted as a little fast, and the touchdown rate was hard at minus 445 fpm. Runway touchdown alignment was perfect.

With a final score of 83.8 %, the landing was solid overall; focus on reducing the threshold and touchdown speeds to their targets and refining the flare to achieve a softer touchdown rate while maintaining the excellent alignment.
