A method for controlling a hose tension in an air-to-air refueling 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.
