Defense Giant Highlights Complex Path to Safe Drone Delivery Integration

Major questions about airspace safety and integration challenges need to be addressed before drone delivery services can fully take off, according to insights from Northrop Grumman and other key industry players in a recent comprehensive report.

Complex Integration Challenges

Northrop Grumman’s director of airworthiness and airspace integration, Doug Davis, emphasizes that drone operators must work within established aviation frameworks:

“If you’re going to operate new aircraft, you need to operate them within the same framework of operational risk and requirements that apply to all aircraft operating in domestic airspace.”

Progress Despite Challenges

The industry has seen significant advancement in recent years. UPS and Matternet received FAA authorization for medical supply deliveries in March 2020, with UPS later expanding to commercial home deliveries in California. In another milestone, Wing Aviation secured the FAA’s first commercial drone delivery certification in 2020. Most recently, as of August 2023, UPS gained clearance for beyond visual line of sight (BVLOS) operations.

Technical Hurdles and Solutions

Urban environments present unique challenges through microclimates that can significantly impact drone operations.

“These microclimates can really challenge your situational awareness of current flight conditions, particularly if you’re operating the drone BVLOS,” explains NASA Ames’s Marcus Johnson.

RF interference poses another significant hurdle.

“For command and control, drone operators often use the same unlicensed frequency bands — 2.4 GHz and 5.8 GHz — used by residential or commercial Wi-Fi routers,” Johnson notes.

This shared frequency usage can lead to sudden communication losses in urban areas, creating potential safety risks.

FAA’s Collaborative Approach

The FAA has adopted a measured approach to integration, working closely with NASA on the Unmanned Aircraft System Traffic Management (UTM) system. Rather than mandating specific design requirements, they’re focusing on performance-based safety standards. This strategy is currently being tested through a North Texas consortium evaluating multiple drone services, though all package delivery drones still require airworthiness certificates.

Industry Response

UPS has taken a proactive role in building public confidence through various initiatives. Their public demonstrations span both urgent commercial and non-urgent residential deliveries. They’ve also partnered with GAVI and Zipline for medical deliveries in Africa, using these experiences to help shape U.S. drone policy development.

DroneXL’s Take

From a drone technology perspective, we’re seeing a careful balancing act between innovation and safety. The concerns raised by Northrop Grumman, coupled with the FAA’s methodical approach and industry advancements, suggest that while drone delivery is inevitable, its implementation will be gradual and safety-focused. The UTM testing in North Texas could provide crucial data for expanding these services nationwide.
