Line select key 4L terminates the engine out takeoff mode and activates the
normal climb mode.
Climb Phase
During the takeoff flight phase prior to the flap acceleration height the FMC
calculates and issues a speed target equal to V2 + 20 KCAS. V2 will be obtained
from the MCP speed window. The V2 speed set in the MCP speed window cannot
be changed after reaching 60 knots. VNAV continues to generate this speed target
until reaching the all engine acceleration height indicated on the TAKEOFF REF
page. The speed target then changes to the pre-planned climb speed profile subject
to applicable speed limits for the current configuration.
Climb Profile Speed Targets
With VNAV armed for the climb phase, VNAV commands acceleration to:
• last MCP speed (V2) + 20 kts until acceleration height
• the flap placard speed minus 5 kts
• 230 kts or less when leading edge flaps are not fully retracted
• 250 knots with flaps retracted
• the active target speed
