The question
What happens to a slow-responding hauler arriving at a street-side pad as wind disturbance increases?
The flight
The campaign scored scheduled hauler landings at the Seventh Avenue pad across 200 fresh seeds. The vehicle response, loading and disturbance model were assumed. Of 2,000 requested arrivals, 1,714 were scheduled in the comparison; the held arrivals are reported separately in the research record.
What happened
Calm conditions produced no bad endings among the 1,714 scheduled landings. The 1 m/s disturbance package produced 10.04 bad endings per 100 landings. A stronger station-keeping setting reduced that to 1.69. Planning a slower final approach raised it to 21.2. At 2 m/s the pad stopped operating sufficiently for the registered dose comparison.
What we learned later
Amendment (2026-10-10, CRAFT cycle 34, provisional). The gap between the 1 m/s package and the 2 m/s stop was then measured on 200 fresh seeds: bad endings per 100 scheduled landings 9.85 at 1 m/s (this entry’s 10.04 replicated), 25.70 at 1.25 and 45.88 at 1.5, each step adding more than the last; the pad still operated at 1.5 m/s. The station-keeping setting kept its cut at every dose (1.39, 3.65 and 8.35). The approach-leg cost this entry could not measure was read at 1.5 m/s, where the leg had 82 first wall touches to lose: with the setting it had 15, lower on all 60 seeds that differed. The registered reading is that a cost was not shown, not that there is none; arrivals released from a hover at start-up, outside the score, did worse with it. Nothing was adopted.

What this does not establish
A bad ending here means a loss in the final approach or damage at a wall followed by removal. This is one simulated body, controller, site and wind combination. It is not a real aircraft wind limit. The proposed finding awaits the next CRAFT review.
The next question
The controller settings remain experimental. Separating steady wind, gusts and turbulence is an open next step.
