GM1 ACNS.C.PBN.560 Vertical accuracy when
using SBAS/GNSS geometric altitude sources
ED Decision 2019/011/R
The lateral and vertical full-scale deflection requirements detailed in RTCA DO-229D, which is the basis for ETSO-C145c (operational Class 3) and ETSO-C146c (operational Class 3 or 4), ensure an ILS ‘lookalike’ presentation. The deflection may be fully angular with no limitation or angular but bounded at a certain value (e.g. bounded at ± 1 NM laterally and ± 150 m vertically).
