The B 737 has ______ sources of 3000 psi hydraulic pressure

Question

BlackTom AI · Accepted Answer

Begin by identifying what the question is asking: the number of sources of 3000 psi hydraulic pressure in the Boeing 737. 
Option 1: 4. This would imply there are four independent sources capable of delivering 3000 psi. In the 737, the hydraulic architecture is usually described as having more than four supply paths due to the combination of engine-driven pumps and electric pumps, so labeling only four would undercount the system if multiple pumps are used to maintain pressure or supply different systems. 
Option 2: 3. Claiming only three sources would oversimplify the hydraulic system. The 737 employs multiple pumps to ensure redundancy and adequate pressure for all systems, especially during abnormal or single-pump failures, so three sources would be insufficient to meet the standard redundancy and capacity. 
Option 3: 5. This option reflects recognizing multiple independent sources (for example, engine-driven pumps along with electric motors or standby pumps) that collectively provide hydraulic pressure at 3000 psi to the aircraft’s systems. In typical 737 configurations, there are several pumps/power sources that contribute to the 3000 psi supply, offering both redundancy and sufficient flow. 
Option 4: 6. Asserting six sources would imply more independent pressure sources than are standard for the 737’s hydraulic architecture. Unless there is a very specific variant or configuration, six sources would exceed the documented count for standard models and could misrepresent the system's redundancy. 
In summary, the correct choice aligns with the known count of pressure supply sources in the 737’s hydraulic system, while the other options either understate or overstate the number, or reflect configurations not typical to standard variants. The reasoning for each incorrect option focuses on why it would misrepresent the actual redundancy and capacity of the 3000 psi hydraulic supply in the 737.
