A method for evaluating a collective alignment of rotor blades (215) for an aircraft while the aircraft is on the ground is disclosed. The method includes evaluating a collective condition for an aircraft, via an auto-rotative test flight and d etermining a first engine torque value for the aircraft while the aircraft is on the ground and the aircraft rotor blades are at a normal speed. The method further includes associating the first engine torque value with the collective condition; determining a second engine torque value for the aircraft while the aircraft is on the ground and the aircraft rotor blades are operated at a normal speed; and providing an indication of the collective condition if the second engine torque value is within a tolerance limit of the first torque value.
