A so-called full stall landing is one whereby the aircraft is held off within a foot of the ground for as long as elevator authority will allow, before settling onto the runway at a low forward speed with the stall warner blaring. Ground effect delays an actual stall in this condition.
Use of this technique is probably the practical ideal for simple single-engine training aircraft. The landing performance charts for these aircraft usually stipulate 'power off' and the normal operations section usually advocates touching down at the slowest possible speed. Both of these conditions allude to the aircraft having been designed to perform 'full stall' landings.
Aircraft with high wing loadings typically need to be flown onto the runway as they tend to drop like a stone when power is removed.
