The airplane will accelerate towards the surface of the earth which, if not accounted for, will result in a structural failure of the aircraft.
If the aircraft's altitude is constant, that means its vertical speed is zero. That indicates zero vertical component of any acceleration, which in turn implies that vertical force components are balanced. So you can say with assurance that the sum of (lift produced by the wings) PLUS (any vertical component of thrust due to a positive angle of attack) is equal to the airplane's weight (gravitational force on it).
The force that counteracts the weight of an airplane is called lift. Lift is generated by the wings of the airplane as it moves through the air. The amount of lift produced needs to be equal to or greater than the weight of the airplane to keep it in the air.
Begin to succumb to the power of gravity because of the decrease in lift
The net force on the model airplane is the vector sum of all the forces acting on it, such as lift, weight, thrust, and drag. If the net force is zero, the airplane will remain in a state of constant velocity or at rest, according to Newton's first law of motion.

Lift
the difference between an helicopter creating lift and an airplane creating lift is simple. an airplane creates lift by moving forward and its wing that has an aerofoil shaped will create lift. this gives the lift for the airplane and to fly. for helicopters, instead of the aerofoil is fix like an airplane, the aerofoil wing is rotating and create lift. that is why the helicopter does not need to move forward to gain momentum to create lift. by rotating the aerofoil (the blade) the helicopter can creates enough lift to lift up the helicopter.and that's how it fly..
The importance of wings is critical to an airplane, they produce lift that can sustain the airplane in the air.
The force that counteracts the weight of an airplane is lift, which is generated by the wings as the airplane moves through the air. Lift opposes the force of gravity acting on the airplane, allowing it to remain airborne.
I am going to assume that aeroplane=airplane when I answer this. An airplane stays in the air by generating lift on its wings. As long as an airplane can generate sufficent lift it can stay in the air. However once the lift being generated falls below what is required for the plane to stay up... uh oh.
Nothing. There is no air to give it lift. It would fly as far as you could throw it before it settled on the surface.
