is. Flight simulation of a power unit in itself. The torque from the rotating blades coming loose tire. To create traction Or pushing motion flight simulator The air force flying tire freely without radio and any mechanism to control the orientation of the

gravity (Gravity force or Weight) due to gravity. This strong push or pull air down to earth acts at the center of the aircraft's primary flight trials of aviation forces acting on the aircraft fuselage. Flying in the air Because there are four forces acting on the aircraft, the four forces will act at all times while the airplane is in the air force, the fourth is 24 : 1. Lift (Lift) 2. Gravity (Gravity Force or Weight) 3. . thrust forward (Thrust) 4. resistance or traction (Drag) Lift (Lift) occurs. The low pressure Occurred on the upper surface of the wing compared to the pressure on the lower surface of the wing. In other words, it is the force that occurs on the top surface of the wing is less than the force that occurs on the surface of the lower wing. According to Bernoulli's principle. Upward lift force. The wing of a plane powered (Thrust) is the force that drives forward the momentum generated by the engine or traction. Of plane Whether a piston engine, turbo-jet engine. Or turbofan , Suction rotor resistance (Drag) as opposing forces. The force that propels the plane forward, especially as a force against. The movement of objects in the air A direction parallel to the moving object here is that the friction of the air through the various sections. Of the aircraft. Resistance caused by the impact of air. The friction surface of the aircraft and the air suction replaced.
