and just to keep king happy heres what the 777 FCOM says about pushing TOGA
On the ground:
Push –
• below 50 knots and flaps out of up, activates autothrottle in THR REF
mode at thrust limit selected on THRUST LIMIT page. If not pushed
below 50 knots, autothrottle operation is inhibited until reaching 400 feet
altitude
• pushing either switch above 80 knots disarms LNAV and VNAV
In flight:
Push (after lift-off with takeoff thrust limit displayed) –
• removes takeoff and climb derates and assumed temperature thrust
reduction
• A/T in HOLD, activates A/T in THR REF mode
• disarms AFDS modes
• between 50 feet and 400 feet, selects TO/GA roll mode
• above 400 feet, selects TO/GA roll and pitch modes
Push (on approach with flaps out of up or glideslope captured) –
• activates autothrottle in THR mode with GA thrust limit displayed
• disarms AFDS modes
• selects TO/GA roll and pitch modes
XXXXX - (a/c registrations)
• arms or engages LNAV if an LNAV path is available
• second push – activates autothrottle in THR REF mode
