Compressor stalls on the number 2 engine was and still is a problem in the Boeing 727 during takeoff with a strong crosswind from either side around 60 or more degrees with wind near 20 knots or higher.

Standard procedure to avoid this problem was bring 1 and 3 up to max EPR while sitting static on the end of the runway. As airspeed increased to 70-80 IAS either the NPF of the FE would bring #2 up to max EPR. The stronger the crosswind the more airspeed was needed to avoid the compressor stall. However, sometimes no matter what you did you would still have the #2 bang a couple of time.

As far as I know the 727 was the only tri-jet to have this problem. I know the Falcon 50/900 had no problems in this area.
