Except for the high hover and low hover procedure, what is the minimum airspeed required to manipulate the training switch?

• A. 30 KIAS
• B. 40 KIAS
• C. 50 KIAS
• D. 60 KIAS

Answer: (B)

Operate the training switch only when you have enough forward airspeed to put the helicopter into translational flight so the controls behave predictably. At about forty knots, you get sufficient translational lift and airflow over the rotor system to minimize abrupt control responses or gust effects when the training mode is engaged. This keeps the aircraft within a stable, controllable regime during the switch operation. Hover conditions—both high and low—are treated as exceptions because they have different aerodynamic characteristics, which is why there are procedures that allow switch manipulation at lower speeds during those specific hover maneuvers. Speeds lower than forty knots don’t provide the needed translational lift, and higher speeds aren’t required for this operation and could unnecessarily limit maneuverability.
