Utter rubbish Vilas,
PWS on take off is a mandatory rejected take off action as instructed by Boeing. Why on earth would you want to take off into it if you have a choice.
Agg Karan.
PWS will activate above 100kts. Try it in the Sim. Its all about RTFQ. " No NEW PWS warning alerts " after 100 kts. So if it is just before 100 and remember you are accelerating then the warning will actually be running well after 100kts.
