Post Production of Lift

Hey,

My name is Ryan, I'm currently working towards a Commercial License. I'm a little bit confused about the production of lift.

Just recently, I read an article about this very point, and the conclusion was Bernoulli's Principle only contributes to 2% of Lift produced while most Lift produced is based on Newtons Third Law, for every action there is an equal and opposite reaction. After doing some research, looking at NASA webpage and RAF webpage. I came to the conclusion that they also dispute Bernoulli's Principle, and agree that Newtons Third Law is the fundermentals for production of lift - like it to water(fluid) running over a spoon.

Every text book you read, describes lift production around Bernoulli's Principle - High's and Low Pressures etc. I'm just wondering what peoples ideas are and their conclusions, and if other fundermentals, like drag, and especially production of thrust is effected.

I hope you sort of understand my query,

Ryan
