This is how I set it up in my lesson plans;
Fly along the taxiway. Just before reaching an intersection, say "quick stop". The student "quickly", and "abruptly", "jams on the brakes"! The point being to stop just before reaching the intersection. (20-25ft / 40kts) (similar to a takeoff run)
teaching environment we should all be cautious of the words we use and how they
maybe misunderstood. You’re correct in that the Quick Stop can be preformed
with a quick and/or rapid cyclic application. That would then require an
equally rapid application of collective and pedal to maintain coordination. The
Quick Stop, in any case, is still preformed with smoothness and coordination.
never be any abrupt control movements, except in case of emergency. Abruptness
is a sudden unexpected (unplanned) action lacking continuity.
Moving fast or doing something in a short time;
prompt; happening with little or no delay.
Happening in a short time or at a fast pace;
characterized by great speed.
Sudden and unexpected; not flowing smoothly;
disjointed; lacking smoothness or continuity.
PTS sets the standard for training and testing in the U.S. As such, the PTS
references the standards for the Rapid Deceleration in FAA-H-8083-21 (pg. 10-3),
which calls for the maneuver to be performed slowly and smoothly with the
primary emphasis on coordination.

operations, use the rapid deceleration or quick stop maneuver to slow the
helicopter rapidly and bring it to a stationary hover. The maneuver requires a
high degree of coordination of all controls. It is practiced at an altitude
that permits a safe clearance between the tail rotor and the surface throughout
the maneuver, especially at the point where the pitch attitude is highest. The
altitude at completion should be no higher than the maximum safe hovering
altitude prescribed by the manufacturer. In selecting an altitude at which to
begin the maneuver, you should take into account the over all length of the
helicopter and the height/velocity diagram. Even
though the maneuver is called a rapid deceleration or quick stop, it is
performed slowly and smoothly with the primary emphasis on coordination.
