A method for controlling a hose tension in an air-to-air refueling (AAR) operation from a tanker aircraft to a receiver aircraft , the AAR operation performed with a refueling device system which comprises a hose and drogue device for delivering fuel, extendable and retractable from and to the tanker aircraft by a drum device , and a probe on the receiver aircraft , extendable and retractable from and to the receiver aircraft for receiving fuel, wherein the hose and drogue device includes a hose , a reception coupling unit at the end of the hose and a drogue attached to the reception coupling unit , the method comprises: during a stand-by phase wherein the tanker aircraft waits for the receiver aircraft : applying a torque T 0 to the drum device of the refueling system based on a predetermined stand-by hose tension Ro that permits a contact of the drogue and the receiver aircraft ; and measuring an acceleration A of the drogue , during a contact phase between the drogue and the receiver aircraft , the drum device having a torque Tc and an angular acceleration α, the method comprises the step of modifying the torque Tc applied to the drum device to obtain a desired hose tension Rc applied at the end of the hose by measuring the drum device angular acceleration α: if the acceleration A does not avoid a whipping effect of the hose and drogue device, increasing α by increasing the torque Tc to obtain a desired hose tension R c1 that avoids whipping, if the acceleration A does not avoid a false contact of the hose and drogue device, reducing α by reducing the torque Tc to obtain a desired hose tension Rc2 that avoids a drogue sail-away, wherein the desired hose tensions Rc1 and Rc2 are based on a momentum M applied to the drum device according to: M = I * α wherein I is the moment of inertia. during a stand-by phase wherein the tanker aircraft waits for the receiver aircraft : applying a torque T 0 to the drum device of the refueling system based on a predetermined stand-by hose tension Ro that permits a contact of the drogue and the receiver aircraft ; and measuring an acceleration A of the drogue , applying a torque T 0 to the drum device of the refueling system based on a predetermined stand-by hose tension Ro that permits a contact of the drogue and the receiver aircraft ; and measuring an acceleration A of the drogue , during a contact phase between the drogue and the receiver aircraft , the drum device having a torque Tc and an angular acceleration α, the method comprises the step of modifying the torque Tc applied to the drum device to obtain a desired hose tension Rc applied at the end of the hose by measuring the drum device angular acceleration α: if the acceleration A does not avoid a whipping effect of the hose and drogue device, increasing α by increasing the torque Tc to obtain a desired hose tension R c1 that avoids whipping, if the acceleration A does not avoid a false contact of the hose and drogue device, reducing α by reducing the torque Tc to obtain a desired hose tension Rc2 that avoids a drogue sail-away, if the acceleration A does not avoid a whipping effect of the hose and drogue device, increasing α by increasing the torque Tc to obtain a desired hose tension R c1 that avoids whipping, if the acceleration A does not avoid a false contact of the hose and drogue device, reducing α by reducing the torque Tc to obtain a desired hose tension Rc2 that avoids a drogue sail-away, wherein the desired hose tensions Rc1 and Rc2 are based on a momentum M applied to the drum device according to: M = I * α wherein I is the moment of inertia. <EOS>
