1/ Apply thrust ( t/o Config warning will sound )
2/ At VRef AND thrust set Rotate
3/ Once airborne Push Toga ( Boeing )
4/ Then continue with a "normal" go around proceedures.
I believe after all wheels on ground,(thrust reversers not deployed), a touch/go maneuver is necessary and not a balked landing which for BOEING is:
1)
Thrust levers mid position,retract speed brakes,retract flaps to 15 while trimming nose around 5 units(737ng).
2)thrust stabilized,apply GA thrust and rotate using white bug.
While a balked landing in the flare area(<50ft) would require to maintain landing pitch while applying GA thrust,when VREF,retract flaps 15 and increase gently pitch to maintain your white bug,about 15 deg.
Autoland practice without prior ATC approval is plain stupid for the reasons mentionned by Dani.
