In one advantageous embodiment, the apparatus includes an air refueling plug-in application capable of calculating air refueling routes for a formation of aircraft and a plurality of plug-in applications. A framework capable of providing framework services to the air refueling plug-in application and the plurality of plug-in applications is present. The apparatus also includes a first interface for the air refueling plug-in application and the plurality of plug-in applications to receive the framework services from the framework. The apparatus also has a second interface for the air refueling plug-in application and plurality of plug-in applications to provide services from one plug-in application to another plug-in application. The first interface and the second interface are independent of the air refueling plug-in application and plurality of plug-in applications. ## Claims ### Claim 1 A method for planning air refueling, the method comprising: receiving, at an air refueling plug-in application, first data for a plurality of receiver aircraft to form received receiver data;
