A movable cargo support for being received in the cargo hold or passenger cabin of an aircraft comprising: a base member having a support surface and a bottom surface opposite the support surface, wherein the support surface is adapted to support one or more cargo elements, wherein the bottom surface comprises one or more support sections, which are adapted to support the base member on a floor surface, and wherein the one or more support sections extend in a common support plane, wherein the base member comprises a plurality of wheel assemblies, wherein each wheel assembly comprises a wheel member which may rest on a floor surface and is rotatable about a rotation axis that is parallel to the support plane, the wheel member being movably mounted on the base member such - that it may pivot about a steering axis of that wheel assembly which steering axis extends perpendicularly to the support plane and - that its position parallel to the steering axis may be altered between an extended position and a retracted position, wherein in the extended position the wheel member protrudes beyond the support plane, wherein in the retracted position the wheel member is retracted from the support plane towards the support surface (Ziffer 5), so that it does not extend beyond the support plane, wherein each wheel assembly comprises a biasing member (49, 55) biasing the wheel member towards the extended position with a biasing force acting in the direction of the steering axis, and wherein the biasing member (49, 55) is configured such that the biasing force is higher than the maximum gravitational force which acts on the wheel member and forces it towards the retracted position when the wheel members are placed on a horizontal floor surface and one or more cargo elements are placed on the support surface having the maximum allowable weight of the one or more cargo elements for the cargo support and wherein the biasing force exceeds the maximum gravitational force by 50 % at most. a base member having a support surface and a bottom surface opposite the support surface, wherein the support surface is adapted to support one or more cargo elements, wherein the bottom surface comprises one or more support sections, which are adapted to support the base member on a floor surface, and wherein the one or more support sections extend in a common support plane, wherein the support surface is adapted to support one or more cargo elements, wherein the bottom surface comprises one or more support sections, which are adapted to support the base member on a floor surface, and wherein the one or more support sections extend in a common support plane, wherein the base member comprises a plurality of wheel assemblies, wherein each wheel assembly comprises a wheel member which may rest on a floor surface and is rotatable about a rotation axis that is parallel to the support plane, the wheel member being movably mounted on the base member such - that it may pivot about a steering axis of that wheel assembly which steering axis extends perpendicularly to the support plane and - that its position parallel to the steering axis may be altered between an extended position and a retracted position, wherein in the extended position the wheel member protrudes beyond the support plane, wherein in the retracted position the wheel member is retracted from the support plane towards the support surface (Ziffer 5), so that it does not extend beyond the support plane, - that it may pivot about a steering axis of that wheel assembly which steering axis extends perpendicularly to the support plane and - that its position parallel to the steering axis may be altered between an extended position and a retracted position, wherein in the extended position the wheel member protrudes beyond the support plane, wherein in the retracted position the wheel member is retracted from the support plane towards the support surface (Ziffer 5), so that it does not extend beyond the support plane, wherein each wheel assembly comprises a biasing member (49, 55) biasing the wheel member towards the extended position with a biasing force acting in the direction of the steering axis, and wherein the biasing member (49, 55) is configured such that the biasing force is higher than the maximum gravitational force which acts on the wheel member and forces it towards the retracted position when the wheel members are placed on a horizontal floor surface and one or more cargo elements are placed on the support surface having the maximum allowable weight of the one or more cargo elements for the cargo support and wherein the biasing force exceeds the maximum gravitational force by 50 % at most.
