AOM 4.20.22
During go-around what does first push of the TO/GA switch do
-roll and pitch activate in TO/GA
-autothrottle activates in (THR) to establish climb rate of 2000 FPM
-the AFDS increases pitch to hold the selected speed as thrust increases
-when current airspeed remains above the target speed for 5s the target airspeed is reset to current airspeed (to a max of IAS/MACH window speed +25kts)
-with an LNAV path available, LNAV automatically arms and activates at 50’ when autopilot not engaged
and 200’ when autopilot is engaged
