for departure, thrust is set at 40% N1 before pushing TOGA, an overshoot of about 4% N1 occurs and finally stabilizes within 2% of the T/O thrust (reduced or full) by 80kts.
There are three phases with different minimum idle settings; ground, flight, and approach. Approach idle has the highest RPM setting, and is maintained as the minimum till touchdown. The approach is flown at an average thrust setting of about 53% N1 for the -700 and 62% N1 for the -800 (moderate landing wts & flaps 30/40). The initial application of TOGA sets a reduced GA thrust with ROC upto 2000 fpm, the second push gives you full GA thrust.
