The ATHC system was placed into conservation mode: target cabin humidity was reduced from 50% to 40% RH, reducing moisture condensation and secondary water recovery flow. Cabin temperature was allowed to drift toward the upper nominal limit (26°C vs. nominal 22°C) to reduce thermal system duty cycle.
