An engine comprising: an engine case, the engine case defining a centerline (C L) and a gaspath within the engine case; a shaft; a fan coupled to a fan shaft; a transmission coupling the shaft to the fan shaft to drive the fan and comprising a gear system; and a gutter system positioned to capture lubricating fluid slung from the gear system, the gutter system comprising: a gutter extending partially circumferentially about the centerline and having a gutter first circumferential end edge; an inlet channel having an inlet at the gutter first circumferential end edge and locally radially outboard of the gutter; and at least one vane (280, 282) spaced apart from the gutter first circumferential end edge; wherein: the at least one vane is at least two vanes, and the at least two vanes are positioned with a leading vane and a trailing vane, the leading vane having an outboard edge and the trailing vane having an outboard edge radially recessed relative to the leading vane outboard edge; characterized in that: the at least two vanes are positioned with a chord oriented with a component from the outboard edge (284; 286) to an inboard edge (288; 290) circumferentially in the same direction as a flow (F 4) of the lubricating fluid slung from the gear system, wherein the outboard edges (284; 286) are leading edges and the inboard edges (288; 290) are trailing edges. an engine case, the engine case defining a centerline (C L) and a gaspath within the engine case; a shaft; a fan coupled to a fan shaft; a transmission coupling the shaft to the fan shaft to drive the fan and comprising a gear system; and a gutter system positioned to capture lubricating fluid slung from the gear system, the gutter system comprising: a gutter extending partially circumferentially about the centerline and having a gutter first circumferential end edge; an inlet channel having an inlet at the gutter first circumferential end edge and locally radially outboard of the gutter; and at least one vane (280, 282) spaced apart from the gutter first circumferential end edge; wherein: the at least one vane is at least two vanes, and the at least two vanes are positioned with a leading vane and a trailing vane, the leading vane having an outboard edge and the trailing vane having an outboard edge radially recessed relative to the leading vane outboard edge; characterized in that: the at least two vanes are positioned with a chord oriented with a component from the outboard edge (284; 286) to an inboard edge (288; 290) circumferentially in the same direction as a flow (F 4) of the lubricating fluid slung from the gear system, wherein the outboard edges (284; 286) are leading edges and the inboard edges (288; 290) are trailing edges. a gutter extending partially circumferentially about the centerline and having a gutter first circumferential end edge; an inlet channel having an inlet at the gutter first circumferential end edge and locally radially outboard of the gutter; and at least one vane (280, 282) spaced apart from the gutter first circumferential end edge; wherein: the at least one vane is at least two vanes, and the at least two vanes are positioned with a leading vane and a trailing vane, the leading vane having an outboard edge and the trailing vane having an outboard edge radially recessed relative to the leading vane outboard edge; characterized in that: the at least two vanes are positioned with a chord oriented with a component from the outboard edge (284; 286) to an inboard edge (288; 290) circumferentially in the same direction as a flow (F 4) of the lubricating fluid slung from the gear system, wherein the outboard edges (284; 286) are leading edges and the inboard edges (288; 290) are trailing edges. the at least one vane is at least two vanes, and the at least two vanes are positioned with a leading vane and a trailing vane, the leading vane having an outboard edge and the trailing vane having an outboard edge radially recessed relative to the leading vane outboard edge; characterized in that: the at least two vanes are positioned with a chord oriented with a component from the outboard edge (284; 286) to an inboard edge (288; 290) circumferentially in the same direction as a flow (F 4) of the lubricating fluid slung from the gear system, wherein the outboard edges (284; 286) are leading edges and the inboard edges (288; 290) are trailing edges.
