A method of determining an actual aircraft ground speed, comprising: receiving, by a processor, a reference ground speed value calculated based on a first wheel speed value from a first landing gear wheel and a second wheel speed value from a second landing gear wheel, wherein the first landing gear wheel and the second landing gear wheel are disposed on an aircraft aft of a nose wheel; receiving, by the processor, a wheel speed value of the nose wheel of an aircraft; comparing, by the processor, the wheel speed value of the nose wheel and the reference ground speed value; determining, by the processor, the actual aircraft ground speed based on the reference ground speed value and the wheel speed value of the nose wheel; and analyzing, by the processor, for a non-use condition prior to the determining the actual aircraft ground speed, wherein the non-use condition is a condition which prevents the processor from utilizing the wheel speed value of the nose wheel to determine the actual aircraft ground speed, wherein the actual aircraft ground speed is determined to be equal to or proportional to the reference ground speed value in response to at least one of the reference ground speed value being greater than the wheel speed value of the nose wheel and detecting, by the processor, existence of the non-use condition in response to the analyzing for the non-use condition, wherein the actual aircraft ground speed is determined to be equal to or proportional to the wheel speed value of the nose wheel in response to the wheel speed value of the nose wheel being greater than or equal to the reference ground speed value, and in response to detecting, by the processor, non-existence of the non-use condition in response to the analyzing for the non-use condition. receiving, by a processor, a reference ground speed value calculated based on a first wheel speed value from a first landing gear wheel and a second wheel speed value from a second landing gear wheel, wherein the first landing gear wheel and the second landing gear wheel are disposed on an aircraft aft of a nose wheel; receiving, by the processor, a wheel speed value of the nose wheel of an aircraft; comparing, by the processor, the wheel speed value of the nose wheel and the reference ground speed value; determining, by the processor, the actual aircraft ground speed based on the reference ground speed value and the wheel speed value of the nose wheel; and analyzing, by the processor, for a non-use condition prior to the determining the actual aircraft ground speed, wherein the non-use condition is a condition which prevents the processor from utilizing the wheel speed value of the nose wheel to determine the actual aircraft ground speed, wherein the actual aircraft ground speed is determined to be equal to or proportional to the reference ground speed value in response to at least one of the reference ground speed value being greater than the wheel speed value of the nose wheel and detecting, by the processor, existence of the non-use condition in response to the analyzing for the non-use condition, wherein the actual aircraft ground speed is determined to be equal to or proportional to the wheel speed value of the nose wheel in response to the wheel speed value of the nose wheel being greater than or equal to the reference ground speed value, and in response to detecting, by the processor, non-existence of the non-use condition in response to the analyzing for the non-use condition. <EOS>
