FAA Policy Statement PS-AIR-25-27 Technical Criteria for Approving Oblique Seats

This policy statement communicates the Federal Aviation Administration (FAA) certification
policy on title 14, Code of Federal Regulations (14 CFR) 25.562 and 25.785, amendment 25-64
or later, for side-facing seats installed at angles greater than 18° up to and including 45° from the
centerline of the airplane as measured from the forward direction (oblique seats). This policy
addresses both the technical criteria for certifying oblique seat designs and the implementation of
those criteria. Current FAA research has only been conducted up to the 45° angle; therefore,
seats installed at more than a 45° angle are beyond the scope of this policy.
