What went well

Touched down at -71 fpm — a soft arrival
Touchdown 478 m in — inside the full-score zone
Straight touchdown — 3.45 m off the centreline, no bounce

What held you back

Departure Climb 3 — climb speed 94 kt against 69 kt at 41 %, −1.97 points
Arrival Approach — 500 ft gate 86 %, −0.95 points
Arrival Landing — Threshold speed at 45 kt was well below target, take care not to stall at 58 %, −0.73 points

Next time

Departure

Reduce climb power to bring speed back to 69 kt and hold it there.

What happened: Climb speed was 25 kt fast at 94 kt during the climb.

Watch for: Airspeed indicator: 69 kt in the climb

See Departure Climb 3

Arrival

Add power on short final to hold 61 kt at the threshold rather than letting speed decay.

What happened: You crossed the threshold at 45 kt against a target of 61 kt, below reference speed.

Watch for: Airspeed indicator, hold 61 kt down to the threshold.

See Arrival Landing

Speed at this height is usually bought with gradient. It's rarely dangerous and it's often just an early acceleration, but with flaps still out you may be heading towards the flap limit and a flat fast climb puts you at the acceleration altitude with the cleaning-up still to do.

Flight narrative

The Cessila 152 taxied onto runway 31 at FJDG Diego Garcia Naval Support Facility and commenced the departure roll. The aircraft lifted off after a take-off run of 785 m, representing 21 % of the runway, at a liftoff speed of 61 kt. Ambient conditions were 16 °C with a wind of 1 kt from 270°, giving a 1 kt head-wind component and a 1 kt cross-wind.

Level cruise began overhead the airport and was maintained for 7 minutes, during which the airplane covered 9 nm at cruise altitude.

During the final descent the aircraft reduced altitude from 430 ft agl to 41 ft agl in 147 seconds, meeting the stabilisation-gate criteria. At this stage the weather was 15 °C with a wind of 1 kt from 270°, providing a 1 kt tail-wind component and a 1 kt cross-wind.

The final approach was executed to runway 13. The descent profile and approach alignment were maintained as described, preparing the aircraft for touchdown.

Touchdown occurred on runway 13, whose length is 3 660 m. The threshold speed was 45 kt, well below the target, and the aircraft touched down at 39 kt after traveling 478 m. The vertical speed at touchdown was minus 71 fpm and the touchdown point was 3.7 m off the centreline. The total landing roll measured 922 m, equivalent to 25 % of the runway, and the rollout alignment was judged very good.

Runway rollout proceeded without deviation, confirming the very good alignment noted at touchdown.

The aircraft taxied from the runway to the parking area in 8 minutes, covering less than 1 nm.

In total the flight covered 14 nm, required 14 minutes of flight time, and consumed 0 kg of fuel.
