UMARK is designed to allow three ground personnel to rig a disabled helicopter for aerial recovery in minimal time depending on team proficiency and the condition of the disabled aircraft. An exception to this timeframe would be the aerial recovery of a CH-47 helicopter, which requires the installation of components from two UMARK kits. Disabled or damaged helicopters may not require stripping of components, defueling, disarming, or need additional maintenance actions performed prior to aerial recovery.
