Abstract: Systems and methods for creating airplane interior modification packages and associated proposals. The method for creating modification packages comprises the following steps: (a) interacting with a user interface presented on a display screen to select a specific airplane type and a specific airplane of the specific airplane type, which specific airplane has an initial interior configuration; (b) interacting with the user interface to select parts to be removed from and parts to be added to the initial interior configuration of the specific airplane to create a modified interior configuration; (c) extracting change results data identifying parts selected for removal and parts selected for addition; (d) creating a modification package that includes drawings and documentation relevant to removing or adding the parts identified by the change results data; and (e) delivering the modification package to an authorized party associated with the specific airplane.
