How to read this site
Locust software output
Generated by the current Cambridge scenario engine from declared assumptions.
Commercial or pilot target
A design choice, price, milestone or acceptance threshold to agree with partners.
Evidence still required
Requires customer data, hardware tests, flight trials, approvals or independent review.
Current modeled result
Useful for choosing what to test.
The headless sweep compares aircraft classes, fleet sizes, demand, tariffs and staffing assumptions. It is a screening tool for narrowing hardware and commercial experiments.
Zipline P2-class aggregate under assisted automation, with the Cambridge Airport FRZ (flown with permission) and Census 2021 population in the routing. The access tariff converted 67.8% of synthetic orders at a £5.03 mean quote; the balanced tariff converted 42.7% at £6.89. The capacity-protective tariff returned £1.00.
Twenty-four Zipline P2-class aircraft, two attempted orders per minute, balanced tariff, 900-second runs and two deterministic seeds.
200 random pickup-to-dropoff routes for a Zipline P2-class aircraft, graded with SORA 2.5 Table 2 against Census 2021 residential density: 194 had an intrinsic GRC of 7 (SAIL VI), 2 crossed areas above 50,000 residents per km2 and fall outside the specific category, and 198 pass through the Cambridge Airport FRZ. Operator mitigations are not included.
A public Flight Review log (1da40610, a quadrotor on PX4 v1.15.4) was replayed through the twin with the vehicle's own speed and acceleration limits. The outbound leg at a steady 10 m/s matched within 2.8 m horizontally and 1% on flight time. The return leg changed speed mid-mission, which PX4 does not log, and missed by 20% on speed. Energy was not compared because the airframe mass is unknown. This is a public log. No Locust flight has taken place.
No Locust flight data, merchant basket dataset, measured noise, approved supervision ratio or customer willingness-to-pay study exists yet.
