Question 224Motor Plants - 1st Asst/Chief

The correct answer is B) The engine speed can be controlled using the fuel control lever without changing the position of the maximum fuel stop. This is the correct answer because when the governor becomes inoperative, the engine can still be controlled manually using the fuel control lever. The maximum fuel stop setting does not need to be changed, as the governor is no longer controlling the engine speed. The fuel control lever can be used to adjust the engine speed as needed. The other options are incorrect because they suggest unnecessary actions, such as disconnecting the linkage or the shuttle valve, which are not required when the governor becomes inoperative. Additionally, replacing the governor with one designed for isochronous applications is not the appropriate action in this scenario, as the focus should be on maintaining control of the engine using the available manual controls.
