Wearable sleep monitoring devices were proposed to better assess aircrew fatigue before an army helicopter crash killed four personnel, an inquiry has been told.
The inquiry into the July 2023 crash also heard the commander of an aviation regiment had proposed a sleep study after identifying fatigue as a key issue for the unit, but it was rejected by headquarters.
Captain Danniel Lyon, Lieutenant Maxwell Nugent, Warrant Officer Class 2 Joseph "Phillip" Laycock and Corporal Alexander Naggs died when a MRH-90 Taipan helicopter crashed into waters off Queensland's Whitsunday Islands.
