Integration Evaluation of the Advanced Mission Extender Device Max

Abstract : The Advanced Mission Extender Device Max (AMXD max) was developed by Omni Measurement Systems, Inc. to provide an improved in-flight urination capability for military aviators. Four participants underwent training, familiarization, and integration assessments in a UH-60 simulator and aircraft, a CH-47, and AH-64, whilst wearing U.S. Army operational ALSE. Overall, the AMXD max was rated as either 'acceptable' (31.5 percent) or 'completely acceptable - no improvements needed' (68.5 percent) in all phases of this study. The device will not accommodate all anthropometric sizes, but should fit 90 percent of male aircrew and up to 95 percent of female aircrew. The key integration issue concerned the potential for urine collection bag damage and rupture in the underside of aircrew seats both the UH-60 and AH-64. It is probable that this issue could be overcome by use of the alternative shorter urine collecting tubes, and polymer-filled disposable urine collection bags. Once the integration issues are resolved this system has strong potential to improve crew comfort and endurance on U.S. Army rotary wing aircraft.
