I think it is a full throttle rate in which a jet airliner doesn’t do as far as I know. It will fly at 3/4 - 7/8 of full throttle during its flight time. Full throttle at the full flight time isn’t done.
You are correct. Typically, a jet airliner doesn't even use full throttle at take-off. Sometimes transatlantic aircraft might use full throttle at T-O. (They use reduced power to lessen the strain on the engines. Thrust values are calculated for each take-off). There are a vast amount of throttle (power) settings for aircraft based on type engine, pressure altitude, etc. 90% power is fairly common.
