While there’s been uptick in news about supersonic aircraft this year, FAR Part 91.817 is seldom mentioned. That regulation prohibits operation of a civil aircraft over the Continental United States or at a U.S. airport when the aircraft is capable of true airspeeds greater than Mach 1, the speed of sound. The regulation also represents a significant impediment to introducing Americans to the time-saving benefits of supersonic travel.
Honeywell and NASA Create Sonic Boom Predictive Software
Key Takeaways:
- US regulation FAR Part 91.817 prohibits supersonic flight over land, significantly impeding the reintroduction of supersonic travel.
- Honeywell and NASA developed a new pilot interface that integrates predictive sonic boom software and display technology into the cockpit.
- This system helps pilots understand and alter course to prevent sonic booms from disturbing people on the ground, supporting NASA's efforts to potentially negate the need for 91.817.
