18 minutes
closes a runway.

Every commercial airport in the Gulf has moved from "monitoring" to "ready to close" in the last three years. RADI is being designed as the sensing + response layer that keeps a runway open, safely, when a drone appears.

§ 01— The threat here

Four ways a drone
grounds an airport.

01
— INADVERTENT INCURSION

Hobbyist, wrong day.

The majority of runway closures. Innocent — but the airport still shuts. Design intent: rapid ID, rapid mitigation, rapid re-open.

HARAS · CLASSIFICATION ACCURACY
02
— DELIBERATE DISRUPTION

A rented drone. A grudge.

The Gatwick-2018 problem. A hostile actor with a €2 000 drone and a plan. Design intent: pinpoint the operator via RF-DF, cued to airport police in real time.

RASAD · RF-DF BEARING
03
— FUEL-FARM ATTACK

The tanks next to the runway.

The airport fuel farm is the second-highest-value target after the runway itself. Design intent: continuous sensor coverage plus first-response soft-kill.

SAMT · DIRECTIONAL SOFT-KILL
04
— SWARMED APPROACH

Ten drones. One decision.

Coordinated multi-drone incursions saturating a legacy single-sensor system. Design intent: fused tracks scale linearly with N, cued kinetic layer scales with them.

SAQR · N-VS-N ENGAGEMENT
§ 02— The RADI answer

A recommended stack
for civil aviation.

§ 03— Operational context

Design intent
for tower operations.

— ICAO & GCAA COMPLIANCE

Zero interference with civil air.

SAMT emissions being designed for narrow steered beams within a controlled envelope — no wide-area GNSS jamming, no ILS disruption. All emissions require GCAA-authorised operator ROE.

— TOWER INTEGRATION

The controller already knows.

HARAS is being designed to output ICAO-compatible track messages, integrable with tower ops as an additional overlay, not a parallel system.

— RAPID RE-OPEN

Runway closed to runway cleared.

Design intent: sub-30-second confirmation of "all-clear" after mitigation, with cryptographically signed audit for insurance and regulatory review.
