Final answer:
For normal takeoffs and landings, the hydraulic system B pumps should be selected to the 'ON' position to ensure necessary pressure and flow for reliable operation of the aircraft's critical components.
Step-by-step explanation:
For normal takeoffs and landings, the hydraulic system B pumps are typically selected to the 'ON' position. This is due to the fact that during these critical phases of flight, the aircraft relies on the hydraulic systems for various controls and systems such as landing gear, brakes, and flight control surfaces. Having the pumps in the 'ON' position ensures that the hydraulic fluid is being actively pumped through the system, providing the necessary pressure and flow to operate these essential components reliably.
In certain types of aircraft, particularly larger commercial airplanes, hydraulic systems are crucial for the operation of many mechanical systems. For example, similar to the way hydraulic and mechanical lever systems are used in heavy machinery like backhoes to amplify force and control movements, aircraft hydraulic systems serve a similar purpose in controlling the massive forces on the aircraft control surfaces during flight operations.
The correct question is: For normal takeoffs and landings, the hydraulic system B pumps are selected:
a) AUTO
b) OFF
c) ON
d) MANUAL
