• all descent altitude constraints below the current airplane altitude are
deleted; the waypoints are retained in the active flight plan
• the new cruise altitude becomes the greater of the MCP altitude or the
highest altitude in the missed approach procedure
• the FMC transitions from active descent to active climb. This transition
also occurs when the airplane climbs toward the MCP altitude and flaps
are retracted from a landing position (25 or 30 towards 20, or 20 towards
5). For example, when a missed approach is accomplished without pushing
the TO/GA switch
• AFDS guidance to fly the published missed approach procedure to the new
cruise altitude is active when VNAV (and LNAV) are selected
• when cruise phase is active, the speed target is the most restrictive of speed
transition, best hold speed, or ECON cruise (above speed transition
altitude)
