GM1 ACNS.C.PBN.570 Advisory VNAV

• ED Decision 2019/011/R found in: GM Remote Aerodrome Air Traffic Services (ED 2019/004/R) Issue 2 (Jul 2020)

GM1 ACNS.C.PBN.570 Advisory VNAV ED Decision 2019/011/R With reference to (a)(2), the indication should be plain and easy to interpret to avoid confusion. The use of typographic characters (e.g. ‘+’ or ‘/’) as the only means to distinguish whether the vertical guidance is advisory or is referenced to a published procedure is not considered adequate. The use of the function should be documented in AFM, pilot operating handbook (POH) or similar documents and supplements to these documents and should contain a statement to inform the flight crew that, when advisory VNAV is provided, the primary barometric altimeter should be used as the primary reference for compliance with all altitude restrictions that are associated with the instrument approach procedure, including compliance with step-down fixes.
