}Six endpoints covering the full lifecycle — from single-point analysis to fleet-wide carbon compliance.
Single operating-point analysis. Thrust, SFC, CO₂, NOx at any altitude × Mach × TET.
POST /v1/flight/emissions
Gate-to-gate trajectory integration. Multi-segment profiles, per-pax-km metrics.
POST /v1/mission/emissions
Annual fleet-level CO₂ and carbon cost. Mixed fleets, degradation-aware.
