Departure
Reduce climb power to bring speed back to 78 kt and hold it there.
What happened: Climb speed was 23 kt fast at 101 kt during the climb.
Watch for: Airspeed indicator: 78 kt in the climb
Arrival
Reduce power on final so the aircraft arrives at 62 kt over the threshold instead of carrying excess speed.
What happened: Crossing the threshold at 85 kt against a 62 kt target usually carries extra energy into the flare as a balloon, and the sink that returns afterward usually arrives hard at touchdown.
Watch for: Airspeed indicator: 62 kt at the threshold
Fast at the threshold, normal flare, and the runway seems to refuse the aircraft. The instinctive fix - pushing it on - causes the next one. A fast aircraft forced onto the runway touches nosewheel-first or nearly so. The tell is a touchdown that feels soft followed by a bounce that steepens. Pilots fix the bounce recovery; the cause was the 10 knots at the threshold.

The roll
Rotated late
The nose came up at 71 kt, 6 kt after the 65 kt rotate speed.
The pull started after the rotate speed had gone by. Bring the airspeed into the scan as it approaches the rotate speed, so the pull starts on the number rather than when you notice it has passed.
Liftoff and climb
Plan view the roll down the 6,086 ft runway.
Rolled from 174 ft in, never more than 3 ft off the centreline. Airborne 26 % 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 786 ft. The distance scale changes past the runway end.
Reached 35 ft with 3,936 ft of runway left; then climbing at 220 fpm on average to 786 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 dark stretch of the roll is the run with the nose up and the wheels still on, with its length and time under the runway. 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 dashed green line is the speed to rotate at for this aircraft at its weight, and the green dot is where the nose started to come up. The grey band is the run between the nose coming up and the wheels leaving the runway. 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.
The final from 4 nm.
Profile height against the 3° glideslope, with its 2° band in green.
High from 0.6 nm, where the final began, to the threshold (up to 320 ft over).
Your height above the runway against the distance still to go. The glideslope is the steady descent path to the aiming point, 1,000 ft past the threshold: 3° here, which is about 320 ft for every nautical mile out, crossing the threshold at about 50 ft. The row under the distances is the height it puts you at. Inside the green band your path is drawn green; outside it, amber.
Plan distance off the extended centreline, your left at the top, with the 1° band. Sideways distances are drawn 3× larger than distances along the final.
Joined 2,170 ft right of the centreline at 0.6 nm.
Looking down from above, flying left to right towards the runway: up the page is left of the centreline, down is right. Sideways distances are stretched so that small drifts show, so a line that looks wild here may be only a few tens of feet. The labels are how far off you were at each distance, amber when outside the band.
Speed against the approach speed. The green band runs from 5 kt slow to 31 kt fast at the 1,000 ft gate, closing to 19 at 500 ft and 10 at the threshold.
Fast from 0.6 nm, where the final began, to the threshold (up to +23 kt).
Your indicated airspeed down the final, against the approach speed for this aircraft at its landing weight. The band allows 5 kt slow and more on the fast side further out, closing as you get lower, because the speed is expected to come off on the way down. The figures are knots above (+) or below (−) the approach speed.
Over the threshold
The flare strayed well off the target profile
Crossing the threshold 23 kt above target, the flare took all the sink out 25 ft agl above the runway and the aircraft then dropped the rest of the way, 1,033 fpm of sink coming back. Touchdown was 2,401 ft past the threshold. Hold the attitude and let it settle rather than pushing - that excess speed is what turns a normal flare into a balloon, so the fix is on the approach, not in the flare.
Touchdown
Side view — the last 5,000 ft of the approach.
Crossed the threshold at 71 ft, 21 ft above the 50 ft target; began the flare at 29 ft; ballooned 6 ft from 23 ft. Touched down 2,401 ft in, 1,401 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.
From the flare the descent stopped and turned into a climb of 120 fpm before coming down at 920 fpm to touch. The nose went down 1.1° on the way down. Into the flare at 83 kt, 21 kt over the 62 kt approach speed, and 63 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 5 ft right of the centreline. No crosswind: nothing to correct for. Touched down with the nose 3° left of the track, 9.5° 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 2,401 ft past the threshold — beyond the full-score zone. The 2.18 G arrival is the firm side of smooth.
The stop — touchdown to taxi speed.
From 73 kt at touchdown to taxi speed (30 kt) in 1 s, an average deceleration of 4.88 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, a movement that lasted 4 minutes and covered less than 1 nm.
The aircraft commenced its departure roll on runway 36, achieving lift-off after a ground roll of 1,657 ft-27 % of the runway length-at a liftoff speed of 72 kt. Ambient conditions were 60 °F with a wind of 2 kt from 6°, giving a 2 kt headwind and no crosswind.
Following takeoff, the pilot entered a left-hand pattern for runway 36, flying a distance of less than 1 nm in 213 seconds.
The subsequent left-hand crosswind leg of the pattern covered less than 1 nm in 18 seconds.
The downwind turn was executed at a 45° angle to the runway, traversing 5 nm with a measured turn angle of 10.0°.
The downwind leg itself extended 1 nm and was completed in 37 seconds.
The aircraft then established a final approach to runway 18 from the north, aligning on a heading of 183.0° at 4 nm distance and descending to 1,102 ft above ground level.
At 1,077 ft agl the crew initiated a go-around on runway 18, climbing away before re-establishing a subsequent approach.
Subsequent to the missed approach, the Cessna landed on runway 18, whose length is 6,083 ft; the threshold height of 71 ft agl was above the intended target and the published threshold speed of 85 kt was noted as excessively high. Touchdown occurred 366 ft beyond the touchdown zone at a speed of 63 kt, with a heavy descent rate of minus 649 fpm, while runway alignment remained very good. Weather at the time was 69 °F with a wind of 3 kt from 230°, providing a 2 kt headwind and a 2 kt crosswind.
In total, the flight covered 12 nm, required 13 (units as given) and consumed 12 lb of fuel.
