Special Conditions + ELOS findings

Certification-time deviations: SCs add requirements where the design is novel; ELOS allows alternative compliance. Most modern types have both.

  • SC 25-874-SC Special Conditions: Universal Avionics; Electronic System Security Protection From Unauthorized External Access
  • ELOS ODA-ADC-0202-SE-1 Equivalent Level of Safety (ELOS) Finding for Flight Test Requirements for Effects on Pilot Compartment View on installation of the SpaceX Starlink Aviation System
  • ELOS ADC-0202-25.251 Equivalent Level of Safety (ELOS) Finding for Vibration and Buffeting Requirements for the SpaceX Starlink Aviation System
  • ELOS ODA-GED-P342-25.251(b) Equivalent Level of Safety (ELOS) Finding for Vibration/Buffeting Compliance Criteria, Large Antenna Installation
  • ELOS ODA-2585-01-F-1 Vibration/Buffeting Compliance Criteria, Intelsat ESA Outside of Aircraft (OAE) System Antennas
  • ELOS AT11542IB-T-25.1397 Equivalent Level of Safety (ELOS) Finding for LED Position Lights (Alternate Color Definition) Compliance Criteria, LED Navigation Lights System Installation
  • ELOS AT11542IB-T-25.1389(b)(3) Equivalent Level of Safety (ELOS) Finding for LED Position Lights (Overlapping Intensity) Compliance Criteria, LED Navigation Lights System Installation
