Final answer:
The specific button to place the flight director into standby depends on the aircraft model and its avionics. Typically there is a dedicated button on the cyclic, labeled according to the manufacturer. It is advised to refer to the aircraft's flight manual for accurate information.
Step-by-step explanation:
The button that can be used to place the flight director into standby mode varies depending on the specific aircraft model and its avionics suite. Typically, modern aircraft with advanced avionic systems have a dedicated button on the pilot's and co-pilot's cyclic to manage the flight director mode. However, without reference to a specific aircraft model, it is not possible to provide an exact button name or location. The function of placing the flight director into standby might be labeled as 'FD,' 'AP,' or 'standby' depending on the manufacturer. In training or during pre-flight checks, pilots are taught to locate and identify these control features specific to their aircraft.
It is recommended for the student to refer to the aircraft's flight manual or consult with a qualified flight instructor for the accurate information specific to the aircraft being used. Understanding how to control the flight director is critical for effective aircraft operation, especially when transitioning between automated and manual control.
