if an aircraft with a coefficient of lift of 0.05322 is traveling at the velocity of 240 kts at sea level, how much lift is required to fly at level unaccelerated flight if the aircraft weighs 800 lbs? (hint: trick question)

Lift is the force that opposes the weight of an object, such as an airplane. In order for an airplane to maintain level unaccelerated flight, the lift force must be equal to the weight of the airplane. If the lift force is less than the weight, the airplane will descend. If the lift force is greater than the weight, the airplane will ascend.
The amount of lift required for level unaccelerated flight is affected by the weight of the airplane, the speed of the airplane, the shape and size of the wings, and the density of the air. All of these factors must be taken into account in order for an airplane to maintain level flight.
Air density plays a significant role in the amount of lift required for level unaccelerated flight. In denser air, there is more air molecules present, which allows for a greater amount of lift to be produced. In thinner air, such as at higher altitudes, less lift is produced and the airplane may need to increase speed to maintain level flight.
No, an airplane cannot fly without any lift. Lift is necessary to oppose the weight of the airplane and keep it in the air. Without lift, the airplane would simply fall to the ground due to the force of gravity.
The angle of attack, which is the angle at which the wing meets the oncoming air, affects the amount of lift required for level unaccelerated flight. A greater angle of attack can increase the lift force, but if the angle is too high, the airflow over the wing can become disrupted and decrease the lift force. Pilots must carefully control the angle of attack to maintain level flight.
