Flying slower than best-glide speed increases both angle and rate of descent, and there's nothing wrong with throwing in a forward slip
(which, in fact, the test standards specifically acknowledge).
The mathematical model used for dynamic characteristic analysis includes the intrastand equations such as spring equation, rolling force equation, forward slip
equation, and interstand equations such as tension continuity, thickness continuity, and tension differential equations connecting the adjacent stands .
Spondylolisthesis is the term describing forward slip
of a vertebra on its caudal neighbor.
When the load is applied again (Figure 9(b)), the partial reverse slip on the debonding segment transforms to the forward slip
resulting in the reduction of reverse slip length until all reverse slip completely converses to the forward slip
Moreover, friction work at the rollers-workpiece interface can also generate heat, thus it makes temperature change markedly in forward slip
zone and backward slip zone.
Then the anterior body line should be assessed, any disruption indicating a listhesis or forward slip
of the column suggesting a dislocation or fracture (Figs 4 and 5).
Another is the forward slip
, as may be employed when flying that very same short-field approach and landing.
When [v.sub.I] drops, the corresponding forward slip
quantity (([v.sub.I] - R [sub.I][[omega].sub.I]/[R.sub.I][[omega].sub.I]) decreases due to the variations of roll speed ([R.sub.I][[omega].sub.I]) or other process parameters, for example, reduction rate ([r.sub.I]).
(A sideslip differs from a forward slip
, as we might perform when attempting to lose altitude while landing, in that the aircraft will be pointed away from its flight path in a forward slip
A separate but related issue is the terminology used: sideslip and forward slip
. Aerodynamically they are the same--the airplane cannot "tell" the difference.
For crosswind landings, it takes enough of a forward slip
(upwind wing down to prevent drift, opposite rudder as necessary) to maintain runway alignment.
