Spain's AESA Issues First SAIL III Drone Cargo Permit — CATUAV Cleared for BVLOS Flights Over Populated Areas

Spain's aviation safety authority, the Agencia Estatal de Seguridad Aérea (AESA), issued the country's first-ever SAIL III drone cargo authorization on June 30, approving operator CATUAV to fly Swiss manufacturer RigiTech's Eiger 3 drone on beyond visual line of sight (BVLOS) non-hazardous cargo transport and delivery missions over populated areas.

CATUAV and RigiTech Eiger 3 Secure Historic Authorization

The operator behind Spain's milestone is CATUAV — a Spanish firm specializing in unmanned aerial systems (UAS) research, development, and engineering services. The aircraft is the Eiger 3, RigiTech's latest delivery drone, developed by the Lausanne-area Swiss company.

RigiTech has built up years of European flight operations experience and recently partnered with Volatus Aerospace to expand its medical drone delivery footprint. The Spanish authorization is therefore an extension of a deliberate strategy rather than a first attempt. For CATUAV, the permit converts engineering and R&D capability into a commercially operable, repeatable cargo service — not a one-off demonstration flight.

The Eiger platform is a fixed-wing vertical take-off and landing (VTOL) aircraft capable of transitioning from vertical lift to winged cruise flight, and it comes standard with an emergency parachute recovery system. As DroneXL reported in June when Drone Nerds added the Eiger to its U.S. product portfolio, the aircraft carries a maximum payload of 6.6 lb (3 kg), has a maximum range of 62 miles (100 km), and a maximum endurance of 59 minutes.

The parachute is far from a cosmetic specification. Under European regulations, conducting cargo flights over towns requires demonstrating that an uncontrolled descent will not pose a ground risk — and a recovery system is one of the key mitigating measures that makes the risk calculation work.

SAIL III Unlocks Routine Cargo Flights Over Urban Areas

As reported by Seguridad Aerea, SAIL stands for Specific Assurance and Integrity Level — the core risk classification framework within the SORA (Specific Operations Risk Assessment) methodology established under EU Regulation 2019/947. Levels run from I to VI; the higher the number, the greater the operational risk and the more rigorous the burden of proof placed on operators across design verification, crew training, and maintenance procedures.

SAIL III is the threshold at which drone operations cross from "demonstration flights" into "logistics services," covering medium-risk missions such as BVLOS flight over populated areas — precisely the kind of operations required to serve real customers in a cargo network. This authorization covers only non-hazardous goods, the standard first step in cargo permitting; hazardous materials fall under a separate, more stringent regulatory category.

AESA has moved quickly within the European regulatory framework. When the European Union Aviation Safety Agency (EASA) put the updated SORA 2.5 methodology into practice, AESA was the first national authority to publish a country-specific scheme for agricultural spraying operations. Permanent authorization for urban cargo delivery took considerably longer, and CATUAV is the operator that ultimately crossed the finish line.

Europe Advances Through Paperwork; the U.S. Scales Through Contracts

In the same week that Spain authorized its first cargo operator, Wonder and Zipline announced plans to launch drone meal delivery to more than 100 locations across Texas starting January 2027. Zipline alone has logged over 135 million miles of autonomous commercial flight and completed 2.5 million deliveries. Spain — the EU's fourth-largest economy — has just approved its first commercial cargo drone.

America's rapid expansion has a powerful policy engine behind it. As DroneXL reported last year, Zipline's national BVLOS rollout followed an executive order issued in June 2025 directing the FAA to normalize beyond-visual-line-of-sight operations — and the flight gates have been opening steadily since.

Brussels has not been idle, but its energy is directed elsewhere. Just days before the AESA announcement, DroneXL reported that EASA had proposed lowering the drone registration threshold to 100 grams — a rule affecting millions of recreational users. Europe's enthusiasm for regulating the lower end of the airspace is strong; commercial-grade airspace, where the business cases actually live, is moving forward one authorization at a time.

The contrast stings, but it demands context. A SAIL III authorization is not a pilot project — it is a replicable regulatory template. SORA is consistent across EASA member states, meaning the safety case CATUAV has built in Spain strengthens the argument for the next operator in the next country. Europe is slower off the mark but faster toward standardization.

The question is whether standardization can arrive before markets lose patience. European operators are watching U.S. cargo networks sign contracts with retailers and food platforms while their own application files sit in review queues for years.

DroneXL Editorial Perspective

To be clear: one authorization for one aircraft type held by one operator does not constitute a delivery industry. It is one permit. What makes this permit significant is that Spain now has a concrete example of what a SAIL III cargo authorization looks like — and concrete examples are how sluggish regulators are nudged to move faster.

There is a detail worth more attention: the Eiger earned its urban authorization in part because it carries an emergency parachute, because European regulations refuse to allow an uncontrolled aircraft to fall over crowds. That same week, DroneXL reported on a New York Police Department Skydio X10 crashing and catching fire feet away from World Cup crowds in Brooklyn — no parachute, no grounding afterward. One system internalizes the cost of failure before takeoff; the other apologizes after impact.

Whether CATUAV's template will produce a second or third Spanish authorization this year remains an open question rather than a prediction. AESA has published no timeline, and Spain's track record on drone approvals counsels patience.

This author's view: a parachute on a drone is never wasted weight, even knowing that market share goes to the fastest movers. That said, credit is due to AESA for taking this landmark first step.
