To resume the climb, put the clearance altitude into the MCP altitude window and
push the altitude intervention switch. VNAV SPD engages. Pitch maintains FMC
speed and thrust increases to the climb limit. In the example, the airplane climbs
to FMC CRZ ALT and then levels off in cruise.
The altitude intervention switch may be used during climb or descent to delete
altitude restrictions between the current altitude and the MCP altitude. When level
at a restriction altitude, and cleared to a higher altitude prior to crossing the
restriction waypoint, reset the MCP altitude to the new clearance altitude and push
the altitude intervention switch.
In the illustration above, the current altitude restriction is deleted and the airplane
continues VNAV climb to the cruise altitude. T/C moves to match the new climb
profile.
The altitude intervention switch may be used to increase cruise altitude. When
level at a cruise altitude, and then cleared to a higher cruise altitude, reset the MCP
altitude to the new cruise altitude and push the altitude intervention switch.
In the illustration above, the cruise altitude is increased and the airplane enters a
VNAV cruise climb at the economy cruise speed.
