Rationale

The ASTM F3548-21 standard on UTM USS Interoperability has been tested and demonstrated globally and has been identified in the U-space guidance material as a possible means of compliance. This revision of the standard will update the standard to address gaps identified through demonstrations and mapping to the U-space regulation and to meet other anticipated needs. Key topics for the revision will include: • Increased flexibility in allowing conflicts between operational intents when permitted by regulations • Priority and preemption • Negotiation • Related fairness concepts
