Garmin issued a service alert on Thursday that reminds pilots to follow instrument approach procedure minimum descent altitude (MDA) limits when flying an approach with advisory vertical guidance. These approaches are identified by a “+V” indication on primary flight displays.

While the alert doesn’t mention the February 13 crash of an Epic E1000 on approach to Colorado’s Steamboat Springs Airport (KSBS), this accident raised questions about the importance of not following the advisory glide path below the MDA unless the required runway environment is in view.
