In certain missed approach procedures, a fix appears immediately following the MAP (Figure 5-153, '990
ft'). This is not necessarily part of the published procedure, it simply represents a course to an altitude fix.
In certain cases, if the aircraft altitude is below the specified altitude (990 feet) after crossing the MAP, a
direct-to is established to this fix until an altitude of 990 feet reached. After reaching 990 feet, a direct-to is
established to the published fix (in this case POLKE).
If the aircraft altitude is above the specified altitude after crossing the MAP, a direct-to is established to
the published fix (POLKE) to begin the missed approach procedure. The altitude constraint defaults to 400
feet AGL when the fix is not part of the published procedure.
In some missed approach procedures this altitude fix may be part of the published procedure. For
example, the procedure dictates a climb to 5,500 feet, then turn left and proceed to the Missed Approach
Hold Point (MAHP). In this case, the altitude fix would be labeled '5500 ft'. Again, if the aircraft altitude is
lower than this prescribed altitude, a direct-to is established to this fix when the missed approach procedure
is activated.
