// @Param: LAND_SPDWGT
// @DisplayName: Weighting applied to speed control during landing.
// @Description: Same as SPDWEIGHT parameter, with the exception that this parameter is applied during landing flight stages. A value closer to 2 will result in the plane ignoring height error during landing and our experience has been that the plane will therefore keep the nose up -- sometimes good for a glider landing (with the side effect that you will likely glide a ways past the landing point). A value closer to 0 results in the plane ignoring speed error -- use caution when lowering the value below 1 -- ignoring speed could result in a stall.
// @Range: 0.0 2.0

A value closer to 2 will result in the plane ignoring height error during landing and our experience has been that the plane will therefore keep the nose up -- sometimes good for a glider landing (with the side effect that you will likely glide a ways past the landing point). A value closer to 0 results in the plane ignoring speed error -- use caution when lowering the value below 1 -- ignoring speed could result in a stall. Values between 0 and 2 are valid values for a fixed landing weight. When using -1 the weight will be scaled during the landing. At the start of the landing approach it starts with TECS_SPDWEIGHT and scales down to 0 by the time you reach the land point. Example: Halfway down the landing approach you'll effectively have a weight of TECS_SPDWEIGHT/2.
