HF and AnFI,
The S-61N takeoff safety speed (Vtoss) is fixed at 57 kt. The best rate of climb speed (Vbroc) is 67 kt at sea level. The takeoff CDP is 30 kt/70 ft.
During a normal takeoff (with no engine failure) at the CDP, the pilot applies cyclic to rotate the helicoter not more than 20 degrees nose down and accelerates to Vbroc and continues the climb to desired altitude.
Sorry, I omitted the last part of the normal takeoff in my previous post, and that obviously caused confusion.
