beepee and cshahrdar,

Hey guys ___what do you think fellows are doing when making a pass over the runway on edge.

The wingspan is perpendicular to the ground or at least they are trying to, lots of rudder and power is used.
They are trying to have a flight trajectory that is a straight line and paralllel to the ground.

Now changethat banked wing attitude to 45 degrees to the ground instead of perpendicular.
Now reduce the banked attitude to 30 degrees. You now need less power and less rudder to maintain a straigt flight trajectory parallel to the ground.

Your plane is now slipping in the direction of the low wing and the nose is heading the opposite way. The flight trajectory is still a straight line over the ground.

Now imagine that the wind strength (velocity) is making the ground trajectory in line with the direction the nose is pointing; all you have to do is reduce power (set a rate of descent) and at the proper height just flare out and land.

So much for the slipping approach.
Have you not learned how to side slip to loose altitude fast when too high on approach ?
The principle is the same.

For the second case
On final approach starting at some altitude in line with the intended line of touch down like the center line of the runway if there is one, anyone can maintain the wings level and use the rudder to aim the nose into the wind so that the ground trajectory remain a straight lineto the intended line of touch down. That is very easy.

A the time of flare out a bit of rudder and aileron with the elevators to line up the nose and landing gear and touch down. All easy with a bit of practice.

Now that you guys made me write things that you already knew and were pulling my leg,I dedicate this posting to the readers that are interested as to how easy we do things that are not really complicated.

Have a great day guys and look all around when landing with a strong crosswind .
