Soft Field Takeoff and Landing techniques are good skills to have even if you have no intention of exposing yourself or your airplane to the challenge of a real soft field. Most people will learn these techniques on a regular paved runway and seldom, if ever, get to put their skills to work on a real soft field. However, you will definitely be tested on this as part of the private pilot practical test and, in the event of an emergency landing off airport, you will be glad to have this skill available.
To develop your soft field technique, visualize mud. Your objective is to maintain directional control and not get stuck. With just three small wheels and a propeller to work with, this could be challenging. Fortunately, all of your control surfaces can be of use in keeping things rolling and pointed in the right direction. Before you start your taxi, get organized and complete all necessary pre-takeoff checklists so, that at least in theory, you can keep rolling all the way to the runway and take off without stopping. Because of constraints imposed by control towers and crowded tie-down areas etc., you probably will not get to practice this part. A real soft field taxi will require more power than usual to get started and probably more than usual to keep rolling.

In many airplanes such as the Cessna 152, the soft field takeoff is performed with 10 degrees of flaps extended. If flaps are to be used, extend them as you taxi onto the runway. In a real soft field situation, tower and traffic permitting, you would taxi onto the runway without stopping and, once lined up on the centerline, apply full power with the control wheel still in the full aft position. You want the nose wheel to come off the ground at the first possible opportunity, but not so swiftly that the airplane rears up and scrapes it’ s tail on the ground. Most trainers have a tail tie down skid installed to lessen the consequences of scraping the tail. As you add power and accelerate, airflow over the elevator will increase and it will become more effective at raising the nose— so much so that you will probably need to reduce the backpressure on the control wheel slightly to allow the nose wheel to lift off without the tail scraping. As you add power, you also need to add right rudder to prevent your airplane from unexpectedly exiting the runway to the left due to normal left-turning tendencies that are at their most noticeable in high power / high angle of attack angle of attack The angle between the relative wind and the chord line of the wing. situations.
The idea is to get unstuck from the runway at the first possible opportunity and then build up airspeed in ground effect before attempting to climb out. So, you accelerate down the runway with the control wheel positioned further back than for a normal takeoff. The nose wheel will lift off first and, as you continue to accelerate and maintain directional control with rudder the main wheels will lift off. This happens at a lower airspeed than for a normal takeoff and below the speed at which it is safe to climb out. As soon as all three wheels are off the ground, move the control wheel forward to lower the nose into a straight and level attitude. This allows the airplane to build up more airspeed in ground effect before attempting to climb out. Lowering the nose at this point takes some willpower, since it is not intuitive to lower the nose immediately after liftoff when very close
