How often are test planned loads conducted for components 1, 2, and 3?

• A. Every year for AC units; every two years for RC units
• B. Every six months
• C. Every month
• D. Every two years

Answer: (A)

Test planned loads are scheduled based on how often each component tends to drift from its required performance and how critical it is to mission success. AC units experience more frequent thermal cycling and varying operating conditions, so conducting an annual load test helps confirm they can reliably handle the expected demands and maintain cooling performance. RC units generally have a longer service life and slower degradation, so a biennial test strikes a balance between ensuring reliability and managing maintenance costs. Infrequent testing (like every two years for everything) could miss emerging issues, while overly frequent testing (every six months or monthly) not only costs more but may not yield proportional gains for components with lower failure rates.
