What is a "Forward Skip"?

Are the words "avoid" and "prohibited" interchangeable?

In the context it is used, and for my level of flying experience, yes they
are interchangeable. I do not know more about the danger of this than
Cessna, so I would prefer to trust what they say. You level of experience
is certainly different that mine, so your decision may be different than
mine.

That is not say that in the event of emergency I would not perform a slip
to land with full flaps if the need dictated.

and maintain the same ground track.. like the extended centerline on final..
the longitudinal axis of the glider is not lined up with the runway.. but
the ground track is.. a forward slip..

now.. use left bank, and enough right rudder to maintain the longitudinal
axis parallel to the runway centerline.. and you have a side slip.. the idea
is to have just enough slide slip to counter act the cross wind component..
and you land on centerline without any side loads to the landing gear..

in the absence of any wind.. the maneuver would be a slow drift to the side
of the runway to which banked.. with the fuselage parallel to the runway

Slip into the wind. Add hard right rudder, turn the yoke hard left,
add some forwad pressure. This exposes more of the surface to the
wind, and you're able to loss more altitude, without a noticable gain
in airspeed. Some aircraft prhobit slips with flaps extended, others
make no mention.

slip'er... you have them reversed..

I heard references to "forward slip" to get rid of altitude on approach.

Both prior posts pretty much nailed it. A forward slip can be made either
to the left or right. Basically, you intentionally use cross controls
(rudder & aeleron). I believe that a forward slip generally refers to
using
a slip to keep the aircraft aligned with the runway for landing in a
crosswind. This could mean landing on one wheel to maintain directional
orientation. This is my preferred approach when flying in a cross wind in
a
taildragger.

A side slip is similar but in this scenario, the slip is can be more
aggressive. A side slip is used to shed altitude.

When practicing slips, be careful. Remember, you are intentionally using
cross-controls near the ground where inadvertant spin recovery could be
impossible.

I got my call sign "slip'er" because I thought that they were so fun I
always come in high and slip it in.

With full flaps its easy to end up real slow in a slip and approach a stall.

Can someone give me the 2 sentence (or how ever many is adequate) to
what a forward slip procedure is?

I guess that's what we get for answering Ramapriya's questions. We're
turning into rec.aviation.student.

Not with the proper control inputs it's not, nor is that in any way related
to the C172 warning to avoid slips with full flaps.

Sorry, Mike, I was just having some fun with an urban legend, not trying
to come across as some "long in tooth" experienced aviator. I am afraid
I have a long way to go for that title.

As a former owner of a late model Cessna 172, I can tell you that the
"Avoid slips with full flaps" is a Cessna recommendation based the
possibility of some oscillation in the yoke, which can be disconcerting
to a pilot not expecting it. (This is a paraphrase of the POH). This
recommendation has nothing to do with the possibility of a resulting
tail-plane stall and nose-over into the ground, which is where the fear
of avoiding slips with full flaps may have originated.

Is there an older model C172 where re-directed airflow actually can
negatively affect the horizontal stabilizer? I don't definitively know
as I certainly do not know the characteristics of a lot of small
aircraft. However, I don't recall reading about a specific example in
this newsgroup the many times this topic surfaced in the past.

I have slipped with full flaps while practicing emergency descents in
the C172SP and have experienced this oscillation of the yoke; it moves
in and out about a 1/2 or so in either direction and was pretty docile.

Also note that some of the older aircraft and some of the present homebuilts
and experimentals had no flaps,

And even others don't have enough forward view, so flying sideways is
the only possibility to see the runway on final.

I was told many years ago that a full rudder slip in a C172 (especially the
older models with 40deg flaps), it is possible to induce a tail stall....not
good close to the ground....
