Be on speed by the gate
Next time
Adjust power to bring the approach speed onto 146 kt and hold it through the gates.
What happened: The approach speed deviated from the target through the stabilisation gates. This kind of deviation usually carries through to an unstable threshold crossing.
Watch for: Watch the airspeed indicator against 146 kt.
Preparing for a stable approach will give you time to decide on whether to attempt the landing or going around. Too much altitude with a high sink rate will result in carrying too much speed onto the runway. Configuring flaps and the gear late also won't help the speed decay.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway. They are the approach's score: the checks passed out of the checks that ran.
At the 1,000 ft gate: sink rate 1,880 fpm, more than the glideslope needed and speed 68 kt FAST on the reference speed of 146 kt.
At the 500 ft gate: speed 43 kt FAST on the reference speed of 146 kt.
The approach, gate by gate
Side view — the last 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 9,395 ft runway, to the same scale as the side view.
The 1,256 ft touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 737 MAX 8 taxied from the parking area to runway 22L at KORD, Chicago O'Hare International Airport in 11 minutes while covering 3 nm.
During the departure roll on runway 22L, the aircraft used 5,996 ft of runway, representing 74 % of the available length, and lifted off at 165 kt; ambient conditions were a temperature of 76 °F, wind 3 kt from 190°, with a 2 kt crosswind component and a 3 kt headwind.
Climb commenced approximately 1 mile southeast of Bensenville, Illinois, with the airplane accelerating from 1,656 ft asl to 34,001 ft asl, an altitude gain of 32,345 ft achieved in 18 minutes while traversing 119 nm.
The first cruise segment began overhead Monticello, Illinois, and persisted for 75 minutes, during which the aircraft covered 589 nm at level flight.
Descent phase one started 11 nm northeast of 4XS5 Scrappin Valley Airport, Wiergate, Texas, descending from 33,554 ft asl to 17,264 ft asl, a loss of 16,290 ft in 7 minutes over a distance of 51 nm.
A brief cruise interval followed one mile northeast of 98XS LZ Phantom Heliport, Jamestown, Texas, lasting 2 minutes and adding 9 nm to the flight path.
The second descent began 3 nm west of Wildwood, Texas, with the aircraft dropping from 16,564 ft asl to 1,589 ft asl, a decrease of 14,975 ft completed in 10 minutes across 53 nm.
Final approach to runway 26L at KIAH, George Bush Intercontinental Houston Airport, was executed from the east on a heading of 270.0°, intercepting the glide path at 4 nm and 1,461 ft agl.
Touchdown occurred on runway 26L, whose total length is 9,395 ft; the threshold speed was 150 kt, touchdown distance measured 1,260 ft, touchdown speed was 142 kt, and the vertical speed at touchdown was -235 fpm, with runway alignment described as perfect. Weather at the time was 86 °F, wind 2 kt from 150°, a 2 kt crosswind and a 1 kt tailwind.
The rollout covered a total landing distance of 4,162 ft, representing 44 % of the runway, and the aircraft maintained perfect alignment throughout the deceleration phase.
After exiting the runway, the airplane taxied to the parking area in 3 minutes, traveling less than 1 nm.
In total, the flight covered 832 nm, lasted 126 minutes, and consumed 10,118 lbs of fuel.
The Boeing 737 MAX 8 conducted the final approach to runway 26L at KIAH, heading 270.0 ° from the east, at 4 nm and 1,461 ft AGL, with local temperature 86 °F, wind 2 kt from 150 °, a 2 kt crosswind component and a 1 kt tailwind component.
At threshold the height was good and the threshold speed was good at 150 kt.
Touchdown occurred 1,260 ft down the runway, a distance rated good, with a touchdown speed of 142 kt described as a little fast, a touchdown rate fair at minus 235 fpm, and runway touchdown alignment perfect.
The total landing distance was 4,162 ft, representing 44 % of the 9,395 ft runway, and rollout alignment was perfect.
To refine the already high 99.7 % score, reduce the touchdown speed toward the 150 kt threshold speed and aim for a slightly shallower descent rate to improve the fair rate rating.
