Describe the general procedure for testing the UH-60 environmental control system in hot weather or high-load conditions.

• A. Do nothing during hot weather; system is automatic.
• B. Run ECS, monitor inlet/outlet temps, verify pressures and airflow, check for abnormal noises or leaks, and adjust for desired cabin temperature.
• C. Only check the cabin temperature setting.
• D. Disassemble the ECS for manual testing.

Answer: (B)

Testing the UH-60 environmental control system in hot weather or high-load conditions focuses on confirming the system can actively remove heat and keep the cabin at the desired temperature despite increased heat load. The general procedure is to run the ECS and observe key indicators: inlet and outlet air temperatures to verify the heat rejection path is functioning, pressures and airflow to ensure the cycle is operating within specifications and delivering adequate cooling, and checks for abnormal noises or leaks that would signal mechanical faults. Simultaneously, adjust the cabin temperature control to the desired setpoint and confirm the system responds, maintaining the target temperature. In hot conditions, the system is under more strain, so these measurements help verify it can sustain performance without overloading—look for consistent temperatures, stable pressures and airflow, and no signs of leaks or unusual sounds. This approach ensures you’re assessing actual ECS performance under load rather than relying on automatic operation or a single parameter.
