# CifpRestrictiveAirspace

Defines the boundaries and attributes of restrictive airspace areas (MOAs, Restricted, Prohibited, Warning, Alert, and Military Operations areas) as defined in ARINC 424 Section UR records

**Source:** CIFP table `CIFP_RESTRICTIVE_AIRSPACE` · version `239462ba9c35` · effective 2026-04-16

> Each airspace boundary is defined by a series of sequential records forming a closed polygon. The first sequence record (typically CONTINUATION_RECORD_NO=1) contains the airspace limits (LOWER_LIMIT/UPPER_LIMIT). Subsequent sequence records define boundary vertices. MULTIPLE_CODE is used when the same designation has multiple non-contiguous or altitude-separated components.
