1. AICA’s Federal Register Comment on FAA Enabling Supersonic Overland Flight
August 17, 2026 – AICA’s public comment was submitted via Docket No. FAA-2026-6935. The AICA comment includes:
Core Question
- Does the FAA’s proposed interim framework provide enough evidence to authorize civil supersonic overland flight of unspecified scope and duration?
Key Findings
- The proposed 0.11 psf overpressure ceiling does not, by itself, describe noise, vibration, annoyance, repeated exposure, or community effects.
- The proposal does not evaluate all pressure disturbances or acoustic signals that may reach the Earth’s surface.
- The proposal does not provide sound metrics, numerical sound levels, vibration measures, or vibration values for the depicted boom categories and pathways.
- The proposed framework does not specify flight frequency, routes, affected areas, operating hours, monitoring requirements, evaluation milestones, or an expiration or renewal process.
Key Visuals
- Figure 1: What Reaches the Earth’s Surface?
- Figure 2: Continuous Primary-Boom Generation and Additional Arrivals During One Supersonic Flight
- Figure 3: What the Four Categories and Pathways Mean
- Figure 4: What the Proposal Describes and Does Not Quantify
Recommendations
AICA recommends that FAA establish a single national interim framework for this emerging technology, with common operating boundaries, monitoring and reporting of actual operations, scheduled evaluation milestones, and an expiration or renewal process.
