Part 450 Streamlined Launch and Reentry Requirements (2020)
The FAA consolidated seven separate launch and reentry rule sets into a single performance-based framework at 14 CFR part 450. One license would cover a vehicle family across multiple sites, replacing a system where operators sought approvals piece by piece.
Operators gained a single licensing path, but the flight-safety-limit language at 450.108(c)(4) proved ambiguous.
Applicants and the agency spent years arguing over how to calculate conditional expected casualties, producing repeated application exchanges.
The November proposals amend exactly that paragraph, rewording it so operators combine abort and off-trajectory outcomes into one calculation.
