A monitoring system for a dual-stage, separated gas/fluid shock strut, comprising: a controller; and a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising: receiving, by the controller, a primary chamber temperature sensor reading from a temperature sensor coupled to a primary chamber of the dual-stage separated gas/fluid shock strut; receiving, by the controller, a primary chamber pressure sensor reading from a pressure sensor coupled to the primary chamber of the dual-stage, separated gas/fluid shock strut; receiving, by the controller, a shock strut stroke sensor reading from a stroke sensor; calculating, by the controller, a secondary chamber nominal pressure based upon the primary chamber temperature sensor reading; determining, by the controller, a shock strut stroke associated with the secondary chamber nominal pressure; calculating, by the controller, a volume of oil in an oil chamber of the dual-stage, separated gas/fluid shock strut based upon the shock strut stroke associated with the secondary chamber nominal pressure; calculating, by the controller, a volume of gas in a primary chamber of the dual-stage, separated gas/fluid shock strut based upon at least the volume of oil; calculating, by the controller, a secondary chamber inflation pressure; calculating, by the controller, a volume of oil leaked into the primary chamber of the dual-stage, separated gas/fluid shock strut, based upon the secondary chamber inflation pressure; and comparing, by the controller, the volume of oil leaked into the primary chamber with a plurality of threshold values; and issuing, by the controller, a servicing message, in response to the comparing. a controller; and a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising: receiving, by the controller, a primary chamber temperature sensor reading from a temperature sensor coupled to a primary chamber of the dual-stage separated gas/fluid shock strut;
