What is an ELOS finding?
An Equivalent Level of Safety finding allows a project to deviate from a specific 14 CFR requirement when the alternative is shown to provide equivalent safety. Project-specific — not a precedent for other applicants.
14 CFR sections deviation applies to
- § 21.21
- § 21.101
- § 25.1535
- § 33.201
