We had a discussion with friend and we were talking about if the airplane is on approach and the one is landing with tailwind and the other one is landing with headwind, so both have the same value of IAS but the different value of ground speed. Sodoes it means that the airplanes produce in both cases same value of lift or will be the value of lift different? He said that value will be still the same and I was arquining with if you have tailwind you will have to increase angle of attack which means that parazite drag will increase so the value of lift will have to increase.

EDIT: Question is: If two same aircrafts are on same glidepath (descending on ils glide slope) with same IAS but different ground speed, because of headwind acting on one aircraft and the tailwind acting on the other aircraft, will the amount of lift produce by one of the airplanes different or will be both two valeus the same?
