Jan n 1 p 42 + 44 + 46 + 97: Principle of relative motion; variation of resistance of flat plate normal to wind with density, area, and velocity; weight, mass, specific weight, and density; mathematical proof of resistance law; resistance of flat plate perpendicular to wind; general law of variation of aerodynamic forces; angle of attack; span, chord, and aspect ratio; lift and drag coefficients; resultant force and center of pressure. Feb n 2 p 84-87 + 89 + 92: Discussion of why cambered surface is better than flat plate; flow around wing changes with inclination; measuring forces in wind tunnel; pressure of distribution around wing; properties of flat plates; properties of typical wing section; simple relations between wing lift, drag and speed. Apr n 4 p 40 + 42 + 46 + 48: Elements of performance calculation; formulas given for wing horsepower, characteristics of Clark Y airfoil, parasite drag and parasite horsepower, direct calculation of total drag and total horsepower, equivalent flat plate area, and overall efficiency of airplane. May n 5 p 48 + 70-76 + 80 + 58: Elements of airplane mechanics in regard to airplane gliding are discussed and formulas for forces in airplane glide are given; several examples considered; method of gliding into small field; vertical nose dive; maintaining equilibrium in steady horizontal flight. June n 6 p 60 + 63 + 76 + 84: Discussion of centrifugal forces acting on airplane; centripetal force to counteract centrifugal force needed on turns; equilibrium of forces on banked turn; why pilot may lose consciousness on very fast steep bank; lateral inclinometer on bank; incorrect banking; more speed and power on turn; learning to make turn; action of control surfaces.
