Steady flight

Imagine you are on a plane and it is flying through the air. You may have noticed that sometimes the plane goes up or down or might even wobble a bit. This is because the plane is not in steady flight.

Steady flight is when the plane is flying smoothly and steadily without going up or down too much or wobbling. In order for a plane to be in steady flight, many things have to be just right.

First, the pilot controls the speed of the plane by adjusting the throttle. The throttle is like a button that makes the plane go faster or slower. If the plane is going too fast or too slow, it can't be in steady flight.

Second, the pilot adjusts the flaps on the wings to control the lift of the plane. The wings create lift, which keeps the plane up in the air. If the flaps are too high or too low, the plane will not be able to stay at the same height and the plane will not be in steady flight.

Third, the pilot adjusts the pitch of the plane by moving the control stick or wheel. The pitch is the angle of the plane. If the pitch is too high or too low, the plane won't be able to stay at the right height and the plane will not be in steady flight.

Finally, the pilot will adjust the rudder to steer the plane left or right. If the plane is not going in the right direction, it will not be in steady flight.

With all of these things just right, the plane is able to stay in the air at the same height and go in the right direction without wobbling or bouncing. This is steady flight!
