Departure
Lower the nose and add power to raise climb speed to 78 kt.
What happened: Climb speed was 66 kt against a target of 78 kt, running 12 kt slow through the climb.
Watch for: Airspeed indicator against the climb target of 78 kt.
Arrival
Bring the power back earlier on final so the speed settles to 62 kt well before the threshold, instead of carrying it in fast.
What happened: Crossed the threshold at 79 kt, 17 kt above the approach speed; approaches that carry that much extra energy over the threshold usually end up flat on touchdown as the nose stays down, and that combination usually lands firm or hard.
Watch for: Airspeed indicator: 62 kt at the threshold
High on final, the pilot dives to the aim point, converting altitude directly into airspeed, and arrives on-glideslope but 15 knots fast. The vertical profile looks fine; the speed trace does not. It is one of the reasons the stabilised-approach concept - configured, on speed, on path by a gate, commonly 1,000 ft in IMC and 500 ft in VMC - checks speed and path together, and why the tolerances airlines use are asymmetric, typically allowing more on the fast side than the slow, because slow kills faster than fast.

The roll
The nose wandered in the climb
From 35 ft to the end of the climb the nose moved between 1.5° and 16.9°, and the speed between 61 kt and 81 kt.
Once clear of the runway the nose moved through a wide range, and the speed moved with it. Set the climb attitude, hold it and trim, and give the speed a few seconds to settle before correcting it with a degree or two of pitch. Chasing the airspeed with large pitch changes makes it wander more.
Liftoff and climb
Plan view the roll down the 6,086 ft runway.
Rolled from 145 ft in, never more than 5 ft off the centreline. Airborne 23 % of the way down the runway, before the 75 % line.
The roll from above, with your left at the top. The line is where the wheels went, and "widest" is the furthest you drifted off the centreline. Lifting off before the amber 75 % line gets full marks for the roll length.
Side view from the start of the roll to the end of Climb 3 at 970 ft.
Reached 35 ft with 3,980 ft of runway left; then climbing at 810 fpm on average to 970 ft.
The takeoff from the side: the height above the runway against the distance along it. The numbers along the runway are the speeds reached at each point. Lifting off in the amber last quarter of the runway costs marks for the roll length. The shaded stretch is Climb 3, scored on its average speed against the target.
Speed and pitch from brake release to the end of the climb, against time.
Two traces from brake release: the airspeed on top, and below it the pitch, which is how far the nose is above the horizon. The figure at liftoff is the pitch then. The grey dashed line across the pitch is the attitude held from 35 ft to the end: a nose held steady is a climb speed that holds, and the airspeed trace sits directly above it to compare. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.
Over the threshold
The flare strayed well off the target profile
Pitch was -2.8° at touchdown, at or below this aircraft's ground attitude, so the nosewheel met the runway with the main wheels or before them. Touchdown was 2,292 ft past the threshold. Keep raising the nose through the flare so the main wheels touch first.
Touchdown
Rollout
Taxi in
Side view — the last 5,000 ft of the approach.
Crossed the threshold at 83 ft, 33 ft above the 50 ft target; began the flare late, at 11 ft. Touched down 2,292 ft in, 1,292 ft past the ideal 1,000 ft.
The last stretch of the approach and the touchdown, from the side. The height is stretched so that the last few feet show: 80 ft top to bottom, against 5,000 ft across. The dashed line is the ideal, 50 ft over the threshold and down 1,000 ft in. The flare ring is where you began raising the nose, and "descent slowed" is where the sink came off; the figures beside them are the sink rate, pitch and speed at that point.
Sink and pitch — through the flare, lined up with the side view.
The sink grew from 450 fpm at the flare to 680 fpm at touchdown. The nose went down 6.3° on the way down. Into the flare at 60 kt, on the 62 kt approach speed, and 59 kt at touchdown.
Lined up with the side view above, so a point on one sits under the same point of the other. On top, how fast you were coming down: 0 is level, and −600 is 600 ft a minute down. Below, the pitch. In a flare the nose comes up and the descent slows towards 0. The figure at the touchdown line is your touchdown rate.
Plan view — the first 5,000 ft of the 6,083 ft runway, to the same scale as the side view.
Touched down 15 ft right of the centreline, and stayed about there down the rollout, 20 ft right at the widest. No crosswind: nothing to correct for. Touched down with the nose 2° left of the track, 2.3° of bank.
Wind 006° at 2 kt · 2 kt tail · 0 kt across
The runway from above, with your left at the top. Touching down inside the green bracket scores full marks for the distance. The shaded part is the rollout, up to where it ended. The wind is the one recorded at the landing, split along the runway (headwind or tailwind) and across it. To hold the centreline in a crosswind the nose points a little into wind - the crab - and is straightened with rudder just before the wheels touch, often with the into-wind wing lowered to stop the drift. The sentence gives the nose against the direction you were actually moving as the wheels touched, and the steepest bank as they touched, the figure the touchdown's Bank tile marks. The rest of it is shown for reading, not marked.
Touched down 2,292 ft past the threshold — beyond the full-score zone. The 2.00 G arrival is the firm side of smooth.
The stop — touchdown to taxi speed.
From 70 kt at touchdown to taxi speed (30 kt) in 11 s, an average deceleration of 0.20 g.
Your ground speed from the moment the wheels touched until you were down to taxi speed, against the distance rolled. A steep line is hard braking, a shallow one a long, gentle roll. For scale, an airliner's lowest autobrake setting decelerates at about 0.15 g, a medium one about 0.3 g. Shown for reading; not marked.
The rest of the report
The Cessna 172 taxied from the parking area to runway 36 at KAAO Colonel James Jabara Airport in 4 minutes, covering less than 1 nm during the taxi-out.
During the departure roll on runway 36, the aircraft accelerated to a liftoff speed of 67 kt and became airborne after a ground roll of 1,558 ft, which represented 26 % of the available runway. Ambient conditions were 60 °F with a 2 kt wind from 060°, no cross-wind component and a 2 kt head-wind component.
The right-hand pattern entry commenced from runway 36, traversing less than 1 nm in 78 seconds, followed by a brief cross-wind segment of less than 1 nm in 8 seconds. The downwind turn covered 1 nm at an angle of 40.8° to the runway, after which the downwind leg proceeded for less than 1 nm in 5 seconds. The base-leg turn spanned 2 nm with a 152.4° angle to the runway, and the subsequent base leg extended 2 nm in 79 seconds. The final turn completed a 4 nm arc in 125 seconds, positioning the aircraft for the final approach.
Landing was executed on runway 18, whose length is 6,083 ft. The threshold height of 83 ft AGL and the prescribed threshold speed of 79 kt were noted as higher than expected. Touchdown occurred 433 ft beyond the designated touchdown zone at a speed of 59 kt, with a hard vertical rate of minus 468 fpm and a lateral deviation of 15 ft from the centreline. Weather at the time was 59 °F with a 2 kt wind from 060°, no cross-wind and a 2 kt tail-wind component.
The rollout covered a total landing distance of 2,581 ft, representing 42 % of the runway, and the aircraft maintained very good alignment throughout the deceleration phase.
After clearing the runway, the aircraft taxied back to the parking area in 2 minutes, traveling less than 1 nm during the taxi-in.
In summary, the flight encompassed 8 nm of distance, required 13 minutes of elapsed time, and consumed 7 lb of fuel.
