What is the signal for a helicopter pilot to indicate starting the second engine?

• A. Raising one hand
• B. Displaying two fingers
• C. Waving both arms
• D. Throwing a signal flag

Answer: (B)

The signal indicating to a helicopter pilot that they can start the second engine is the display of two fingers. This gesture is a standardized visual communication method in aviation, ensuring clear and unambiguous signaling between personnel. By using two fingers, ground crew or signal personnel can effectively convey the specific instruction to the pilot. This communication is crucial for ensuring safety and coordination on the flight deck, as it minimizes the risk of misunderstandings that could arise from using vaguer signals or gestures. The reasons for not using other methods, such as raising one hand, waving both arms, or throwing a signal flag, stem from the lack of specificity or established recognition in this context. The two-finger signal is universally understood within aviation operations, contributing to a safer and more efficient workflow.
