System Description

MN-FLT-OH-201
After LIFT-OFF:
• if an engine failure occurs, the pitch command target speed is:
•V2, if airspeed is below V2
•existing speed, if airspeed is between V2 and V2 + 20
•V2 + 20, if airspeed is above V2 + 20.
• the A/T remains in THR HLD until 800 feet above field elevation. A/T
annunciation then changes from THR HLD to ARM and reduction to
climb thrust can be made by pushing the N1 switch.
Note:
During a reduced thrust takeoff, a second press of the TO/GA switch
below 800 feet above field elevation will change the thrust limit
mode to GA and N1 reference bugs to increase to full GA thrust,
thrust levers will not be in motion. A second press of the TO/GA
switch above 800 feet above field elevation, thrust levers advance
toward full GA thrust.
• automatic reduction to climb thrust occurs upon reaching the selected
thrust reduction altitude which is shown on the FMC CDU TAKEOFF
REF page 2/2 during preflight, or when the airplane levels off in ALT
HOLD or VNAV PTH. Pilot entries can be made to override the default
value. Allowable entries are 800 feet to 9999 feet.
• flight director engaged status is terminated by engaging an autopilot in
CMD (CMD replaces FD in A/P status display)
•pitch engages in LVL CHG and pitch mode FMA is MCP SPD unless
another pitch mode has been selected
•MCP IAS/Mach display and airspeed cursor change to V2 + 20 knots
•roll mode engages in HDG SEL unless another roll mode has been
selected.
To terminate the takeoff mode below 400 feet AGL, both F/D switches must be
turned OFF. At 400 feet AGL selection of another pitch mode or engaging an
autopilot will terminate the takeoff mode; other F/D roll modes can be also
selected.
