# CifpPathPoint

SBAS (WAAS/LPV) Final Approach Segment (FAS) path point data for RNAV/GPS approaches, defining the precision glide path geometry for each runway

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

> Section code PP. Records with CONTINUATION_RECORD_NO=2 are continuation records and contain null values for most fields. The FAS data block defines the 3D approach geometry used by SBAS avionics. GLIDE_PATH_ANGLE is encoded as an integer (divide by 100 to get degrees, e.g., 0300 = 3.00°). COURSE_WIDTH_AT_THRESHOLD is encoded in hundredths of meters (e.g., 10675 = 106.75m). Coordinates are encoded as signed DMS strings.
