The Braz has got so much power it could fly away with gear down and propeller windmilling.
In the case of the EMB120, it is an aircraft that has to be able to do exactly that to meet the requirements of CAO 20.7.1B.
Not entirely familiar with the Braz but would assume it must have an autofeather system which enables the prop to quickly feather and then the aircraft can meet the CAO requirements. The prop discs on 30 seaters like the braz is huge and a windmilling prop would be the equivelent of about 2-3 tons extra weight. FGD is quite correct in being concerned with these statements and a quick visit to the sim may correct some of these veiws.
