The taxi and landing lights are controlled by what component?

• A. The LDG/TAXI LIGHTS left side PBA if the left seat PIC is selected
• B. Pilot side collective
• C. Overhead panel
• D. A and B

Answer: (D)

The taxi and landing lights on the TH-73A helicopter are controlled by both the left side PBA (Panel Button Assembly) and the pilot side collective. When the left seat Pilot in Command (PIC) is selected, the controls on the PBA provide the pilot with direct access to operate these lights conveniently. In addition, the pilot side collective also has functionality that allows for control over the taxi and landing lights. This dual control ensures that the pilot has flexible options for managing the lighting according to operational needs or situational demands.

Thus, the correct understanding is that these components work together to facilitate the operation of the taxi and landing lights, enhancing both safety and usability in various flight scenarios.
