US Army tests AIRUS in-flight relief system on helicopters

The US Army’s 101st Combat Aviation Brigade conducted first-ever helicopter test flights of the Advanced Inflight Relief Universal System (AIRUS), a wearable in-flight urination solution aimed at reducing “tactical dehydration” and extending mission endurance. The novelty is formal airworthiness/human-factors testing and integration efforts across Apache, Black Hawk, and Chinook fleets to support longer-duration contested-environment aviation missions.
