Why not get into low ground effect before the 38 mph airspeed and then accelerate in low ground effect to as much faster than 38 mph as can be gained in low ground effect before having to zoom over any obstruction? Loss of altitude at 38, the tail slide, is because we are out of ground effect or at too high a nose attitude in too high ground effect. If we get the nose down before she jumps up to ten feet, we will continue to accelerate much faster. At full power the 182 tries to jump out of low ground effect much too quickly. This is especially true with the trim set for takeoff rather than cruise.
At the slow airspeed of a power pitch touchdown with full flaps or lift off as soon as she will fly in low ground effect, the prop blast helps keep the elevator effective. If we have taken the throttle out of the let us down slowly and softly touchdown function, as in round out at considerable airspeed, the nose can be quite heavy and the elevator, while more effective, can require more muscle to pull.
As Starboard points out, the slowness with power of the apparent rate of closure short final approach takes the required heavy pull out of the equation by keeping power on the elevator as long as possible, actually all the way down if we decelerate properly. The deceleration caused by our preventing the numbers to appear to speed up at the bottom, where most pilots just round out, requires power to control the sink at this slow airspeed. Unless we have considerable headwind help, power is required to control the continued deceleration caused descent to touchdown. But if we are going too fast, we have to round our at faster than the airplane will land in low ground effect. Now we have to close the throttle to get down and when we close the throttle we lose that helpful prop blast. When we close the throttle, we have given up the very best sink control to touchdown slowly and softly where we wish. Given a lot of runway we can still use power to control sink to touchdown slowly and softly, as in the soft field landing. All the apparent brisk walk rate of closure approach is is a soft field landing on the numbers using either a shallow or steep descent (not glide as power is still on) angle.
