Exhaust Hazard Areas
My old training notes for the B737Classic fitted with CFM56b2 powerplants shows the exhaust hazard area extending 100ft(30 meters) from the TAIL of the aircraft at IDLE thrust.At BREAKAWAY power this extends to 510ft(155meters).At takeoff power it is 1900ft(579meters).Sorry i don`t have any exact exhaust veloicities.
