Its true. You really dont have the whole picture, by design. Alternate missed approach fixes have been sneaking onto approach charts for a while, but you wont easily find a way to use them. Its even difficult to find out when you would use those alternate holding patterns. [IMGCAP(1)] Those alternate missed approach holding fixes are associated with alternate missed approach procedures. These are in addition to your regular missed approach procedures and are established whenever the…
Alternate missed approach procedures (AMAPs) are un-charted backup plans designed to ensure IFR approach availability if a navigation aid critical only to the primary missed approach fails.
These procedures are typically established for conventional approaches (like ILS) where the final approach and missed approach utilize different navigation facilities.
Pilots receive AMAP instructions verbally from ATC or via FDC NOTAMs, which override primary procedures and can require equipment not used for the approach.
Key challenges include controllers often lacking direct access to AMAP details and aircraft GPS systems being unable to program them, potentially causing pilot disorientation during execution.
It’s true. You really don’t have the whole picture, by design. Alternate missed approach fixes have been sneaking onto approach charts for a while, but you won’t easily find a way to use them. It’s even difficult to find out when you would use those alternate holding patterns.
