Q) profile of "Pushing TO/GA button second time'

[DOGANG KIM 8]

The manual says - With the first push of either TO/GA switch: • thrust advances toward the reduced go–around N1 to produce 1000 to 2000 fpm rate of climb. • 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. etc...- With the second push of either TO/GA switch after A/T reaches reduced go–around thrust: • the A/T advances to the full go–around N1 limit.So what is the profile of Pushing TO/GA button seond time?What will pitch and climb rate will be ? same as first pushing? only faster reahcing air speed?(sorry my poor English)

The second push commands full GA thrust. The climb rate and speed increase are dependant on other variables, such as weight and configuration, verses the first push which gives you a 1000-2000fpm climb. In other words, the second push is full thrust, instead of the first push, which is regulated to 1000-2000fpm.

The airspeeds remain the same. The rate of climb is the difference. The first push gives you enough N1 to climb at 1000-2000fpm. (Maybe 80-85% N1???) The second push gives you GA N1 95-100% and a higher rate of climb.

Ok Thank you.It's sams as 747-400.
