Assuming take off speed is 60kts, when you take off into a headwind of 50 knots, would you take off if you applied 10kts of power or would you still need to add 60kts of power?
You will not start moving over the ground until you have applied sufficient power to overcome the 50 kts of airspeed (not quite true - if you do not have brakes on, a smooth surface and insufficient power the wind
could blow you backwards!) so to start moving you need more than power for 50 kts, especially as you are still on the ground so have ground resistance as well, so to fly you need power for 60kts PLUS enough to overcome the ground resistance.
As someone said, is this serious or are you just yanking our chains?
