SkyGrid, Wisk Aero Propose New Class of Flight Rules to Enable Automated AAM Operations

Why It Matters

AFR promises higher‑density, safer eVTOL operations while reducing air‑traffic‑controller workload, a critical step toward viable commercial UAM services. Its adoption could unlock new revenue streams and reshape urban transportation ecosystems.

Key Takeaways

• AFR complements VFR/IFR with certified automation
• Introduces Class X low‑altitude airspace for UAM
• Enables high‑density eVTOL flights under 4,000 ft
• Reduces controller workload via automated conflict management
• Calls for regulator and ANSP collaboration to validate standards

Pulse Analysis

The rapid maturation of electric vertical take‑off and landing (eVTOL) aircraft has pushed urban air mobility (UAM) from prototype to imminent commercial service. Yet the existing human‑centric air traffic management model, built around Visual Flight Rules (VFR) and Instrument Flight Rules (IFR), cannot sustain the flight tempos envisioned for city‑wide networks. Congestion in low‑altitude corridors, overlapping with Class B, C, and D airspace, threatens safety and limits scalability. Recognizing this bottleneck, SkyGrid and Wisk Aero released a white paper that outlines a systematic shift toward automated flight governance.

The core of the proposal is Automated Flight Rules (AFR), a certified‑automation layer that augments, rather than replaces, traditional VFR/IFR. AFR leverages real‑time data exchange, predictive conflict detection, and pre‑flight demand‑capacity balancing to manage traffic density without constant human controller intervention. A new Class X airspace designation isolates UAM operations below 4,000 feet AGL, providing a dedicated envelope for eVTOLs. By embedding decision‑making algorithms directly into aircraft avionics, AFR promises higher throughput, reduced separation minima, and a measurable drop in controller workload.

Adoption of AFR could accelerate the timeline for commercial UAM launches, offering operators a clear regulatory pathway and investors a more predictable revenue model. Regulators, air navigation service providers, and manufacturers must collaborate to certify the automation stack, define data‑sharing standards, and conduct live‑flight validations. If successful, the framework may become a global template, enabling cities worldwide to integrate autonomous aerial taxis into their transportation ecosystems. The white paper therefore not only presents a technical solution but also signals a strategic pivot toward data‑driven, high‑density urban air mobility.
