I have long been contemplating the forces involved in certain maneuvers in an aeroplane and some of those maneuvers begin to break down my understanding of the forces that specifically oppose gravity. Typically this is described as lift and that is how it is explained in ground school, but they did not go over other forces that can be involved keeping a plane in the air (i.e. a non-horizontal component of thrust etc.). They probably didn't go over this as it doesn't apply (significantly) to the type of planes you're one would fly right after basic ground school.
One of those maneuvers I've thought about is a "slow flight" when performed at an air show by a jet where the jet appears to be going slower than their stall speed and at a very high angle of attack. It seems that a portion, if not all of the force keeping the airplane airborne is coming not from the wings in the form of lift but rather the thrust produced by the turbine. (Example:)
- Is my understanding accurate?
- Is there a good, well known reference to aerodynamics that does not gloss over the entire gamut of forces involved during a wide range of flight situations?
