Pattern Crosswind

Each lap slightly wider and higher than the last, because you're unconsciously using the previous lap as your reference instead of the runway and the numbers. Invisible lap to lap, unmistakable across ten. This is the failure that only measurement catches, because your memory of lap three is gone by lap eight.

Flight narrative

The aircraft taxied from the parking area to runway 31 at FJDG Diego Garcia Naval Support Facility in 1 minute, covering less than 1 nm during the outbound movement.

During the departure roll on runway 31, the Cessna 152 accelerated through a takeoff distance of 616 m, representing 17 % of the available runway, and lifted off at 72 kt. Ambient conditions were 16 °C with a wind of 1 kt from 270°, providing a 1 kt headwind and a 1 kt crosswind component.

The left-hand pattern entry commenced from runway 31, traversing a distance of less than 1 nm in 214 seconds as the aircraft positioned itself for the inbound circuit.

Subsequently, the aircraft entered the left-hand crosswind segment of the pattern, again covering less than 1 nm, this time in 19 seconds.

The downwind turn was executed over a measured distance of 3 nm, with the aircraft establishing a 45-degree angle to the runway and a heading change of 6.8°.

The downwind leg proceeded for less than 1 nm and was completed in 23 seconds, maintaining the circuit alignment prior to final approach.

On final approach to runway 13, the aircraft descended from 634 ft agl to 31 ft agl in 134 seconds, satisfying the stabilisation gate criteria.

Touchdown occurred on runway 13, whose length is 3 660 m. The threshold height was satisfactory and the threshold speed of 46 kt was well below the target. The aircraft landed 351 m from the threshold at a speed of 42 kt, with a smooth touchdown rate of minus 150 fpm. The touchdown point was offset 8.3 m from the centreline. Local weather at the time was 15 °C with a wind of 1 kt from 270°, resulting in a 1 kt crosswind and a 1 kt tailwind component.

The total landing roll measured 687 m, equivalent to 19 % of the runway, and the rollout alignment was slightly off centreline by 8.9 m.

After landing, the aircraft taxied back to the parking area in 2 minutes, covering less than 1 nm during the inbound taxi.

In summary, the flight covered a total distance of 7 nm, required 12 minutes of elapsed time, and consumed 2 kg of fuel.

Landing Score 89.12 %
Landing Summary

The Cessna 152 approached runway 13 at FJDG Diego Garcia Naval Support Facility descending from 634 ft agl to 31 ft agl over 134 seconds and was scored on the stabilisation gates.

During the threshold and flare the aircraft maintained a good threshold height; the threshold speed was 46 kt, noted as well below the target and a reminder to avoid stall risk.

Touchdown occurred 351 m down the runway at a speed of 42 kt with a smooth vertical rate of minus 150 fpm, while the touchdown point was offset 8.3 m from the centreline.

The total landing distance was 687 m, representing 19 % of the 3 660 m runway, and the rollout alignment was slightly off centreline by 8.9 m.

Refine lateral tracking to keep touchdown and rollout positions closer to the centreline, and adjust the approach speed to meet the target value while preserving the safety margin.
