With the first push of either TO/GA switch:
• A/T (if armed) engages in GA and advances thrust toward the reduced go–around N1 to produce 1000 to 2000 fpm rate of climb. The A/T Engaged Mode annunciation on the FMA indicates GA
• autopilot (if engaged) disengages
• pitch mode engages in TO/GA and the Pitch Engaged Mode annunciation on the FMA indicates TO/GA
• F/D pitch commands 15 degrees nose up until reaching programmed rate of climb. F/D pitch then commands target airspeed for each flap setting based on maximum takeoff weight calculations
• F/D roll commands approach ground track at time of engagement. The Roll Engaged Mode annunciation on the FMA is blank
• F/D roll commands hold current ground track at or below 50 feet AGL. Above 50 feet AGL, LNAV will engage. The Roll Mode annunciation will display LNAV engaged above 50 feet AGL.
• the IAS/Mach display blanks
• the command airspeed cursor automatically moves to a target airspeed
for the existing flap position based on maximum takeoff weight calculations.
With the second push of either TO/GA switch (if A/T engaged and after A/T reaches reduced go–around thrust):
• the A/T advances to the full go–around N1 limit
TO/GA mode termination from F/D go–around:
• below 400 feet RA, both F/D switches must be turned off.
• above 400 feet RA, select a different pitch or roll mode.
• if the roll mode is changed first:
• F/D roll engages in the selected mode
• F/D pitch mode remains in TO/GA.
• if the pitch mode is changed first:
• F/D pitch engages in the selected mode.
• F/D roll mode automatically changes to HDG SEL
• the A/T GA mode (if engaged) is terminated when:
• another pitch mode is selected
• ALT ACQ annunciates engaged
