I have to say I only know the basics of how a plane works. But one thing I'm still wondering about; Does the Thrust generated by a plane's engines need to be greater than the weight of the plane, for it to move, and thus take off?
Good question.
The answer is YES, that is if you want to take off with brakes ON!
The static friction coeff on a locked tire on dry asphalt is Cd=1.
This means "breakaway" thrust needed is the same as the Gross weight.
Well, this is "almost" the truth since some of the acf
weight is on the nose gear which does not have brakes
