Boost On / Boost Off
Our airline just started using the 72-500 version of ATR. Earlier 42-500 was a big hit in the airline, apart from its Icing issues. What I am still confused abt is the Boost On and Boost Off charts for ATR 72. The FCOM says nothing abt Boost. I would be highgly grateful if anyone could please enlighten me abt Boost Function, or forward me any write up explaining it. Boost Function under the Powerplant section of FCOM 1 says N/A, but i would still want to know what is it abt.
