Indicated airspeed with a tailwind
Hi ,
If i am in an approach with an indicated airspeed of 70 knots and we encounter a tailwind of 70 knots or more for any reason ,i know my ground speed will increase to 140 knots or more.
Will i stall and lose lift suddenly due wind opposing and destroying the laminar airflow over the wing with a constant indicated airspeed of 70 knots or my indicated airspeed will drop and then we stall ?
If it drops , why ? Shouldnt the IAS remain constant with a tailwind ?
Thanks in advance .
