I'm pretty confident on all of them but #9 - I haven't done slips since before my PPL checkride and haven't had a reason too.  Probably a good reason to go out and do some slips next time I'm flying... Tongue

Other than that, my lips are sealed. Lips Sealed Wink

It's those perfect approaches you fly  Wink  Byproduct of the instrument rating  (you're always ahead of the airplane  Cool  )


Oops.. was that a hint ?

It's a very easy question if you merely use deduction. Can't be #2: not all aircraft have dive brakes or spoilers.
Can't be #3: if rudder and aileron are deflected the same way, you will get a coordinated turn (or perhaps skidding turn, if you use too much rudder).
That leaves #1, although it's a little vague... what exactly does "direction of the slip" refer to? The direction the nose is pointed, or the direction you're slipping?   Huh   Wink

Agreed, I should have looked for a better worded question on slips. This one you can get by process of elimination, but some of these FAA questions you have to be a mind reader to get correct.

I always got the two confused, because they seem (to me) to be named backwards..  i.e. You'd think that what you'd be doing when executing a forward-slip, would be called the side-slip, and vise-versa..  

Hint's all over the place..lol

#9 threw me off because I thought you always slipped into the crosswind on final so you wouldn't have to reverse your slip direction right before roundout.  Or maybe I'm mixing my slips up... Tongue

The Forward slip is to lose altitude..

The Side slip is to counter a X-wind..


Unless it's a significant X-wind.. I don't even think slips..  I just crab my way down, and then at about 100agl get on the rudder, and then land like normal (ailerons to keep on centerline; rudder to keep pointed in the right direction)..

Same here.  I just remember doing forward slips to landing and one of the things I remember is slipping in the same direction you have to crab for the crosswind so you're not swinging the nose from one side to the other right before you land.  But again, that was almost 5 years ago, so there might be some memory inaccuracies in there.  I'll work on that.  Tongue Wink

The way I remember the difference between forward and side slips is to think in terms of the airplane's intended direction... in a forward slip, you're slipping in the direction you're going ("forward"), whereas in a side slip you're slipping in a direction at an angle to your intended direction.
but some people don't think of it that way; they picture where the nose is pointed rather than the low wing (the slip itself is in the direction the low wing is pointed, just as it would be if you slipped during a turn).

That's why the question threw me off- without a reference to that wingtip, it's not very clear.

Here's a quiz question about forward slips:
Q: For what reason, other than to lose altitude (without diving), is a forward slip executed?

Welllll.. if you pitch to hold altitude while slipping; you'll bleed off a bunch of airspeed   Cheesy   ... but that just doesn't feel like the answer you're looking for..  Tongue  Mainly because slipping at an arspeed where you be looking to LOSE airspeed, is too fast to be stressing the empennage..

QUIZ ANSWERS:

1 - C
If another aircraft doesn't have any apparent motion in your window, your flight paths will converge unless action is taken.

2 - C
Wingtip vortices are a product of the wing producing lift. They are present regardless of loading or airspeed.

3 - A
In a quartering headwind, the controls should be held with aileron into the wind. For a left quartering headwind, use left aileron, which translates to left aileron up.

4 - B
Density altitude is pressure altitude corrected for nonstandard temperature. Height above the standard datum is pressure altitude. Altitude read from the altimeter is indicated altitude.

5 - A
The horizontal component of lift acts to turn the aircraft. The vertical component balances the weight of the aircraft. The centrifugal force is a result of the turn and balances the horizontal lift component.

6 - A
The aptly named carburetor heat heats the air entering the carburetor. The air becomes less dense when it is warmed which serves to enrichen the fuel/air mixture, decreasing engine performance.

7 - A
Class A airspace extends from FL180 to FL600 and requires that you be on an instrument flight plan.

8 - C
This was the most missed question. The required fuel reserve for nighttime VFR operations is 45 minutes. The reserve for daytime VFR is 30 minutes.

9 - A
Again, sorry for including this poorly worded question. You can eliminate dive brakes or spoilers, they are another means of glide path control independent of slips. You can also eliminate rudder and aileron deflected on the same side as a slip is preformed by crossing the rudder and aileron controls. This leaves only the poorly worded answer A.

10 - B
I'm glad to see everyone go this question correct. Everything from deciding the plane is airworthy before setting off flying to deciding how to handle an onboard emergency, the PIC is the final say.

I agree and disagree. Yes, in a forward slip, you are slipping in the direction you are going (forward), but the whole point of a forward slip is to lose altitude if you find yourself too high on an approach.  A forward slip should be conducted with power at idle, so you lose altitude as fast as possible, otherwise there is no point of forward slipping in the first place.

Now for a side slip, yes, in calm wind, you will be slipping towards the downward wing, but once again, the point of side slipping is to combat a crosswind.  So with the crosswind pushing in the other direction of the slip, the nose should be tracking forward (right down the centerline of the runway).  Maybe i was just confused with what you were trying to say, correct me if i'm wrong  Smiley

By my lights, in the phrase "forward slip", the word "forward" describes the slip. It can be safely assumed that the airplane itself is moving more or less forward. Grin

Whether one is forward-slipping to lose altitude or for fun, the fact remains that the sideways movement of the plane (the slip) is "forward" relative to the direction of flight, although "sideways" relative to the airplane.
  In a side slip, you're slipping off to the side relative to both the airplane and the direction of flight. You only maintain your intended track in a side slip because of opposite rudder and/or a crosswind.

Or look at it this way: if you use rudder and aileron so that the nose is pointed away from the direction of travel (which we might agree can be called "forward"), you are slipping pretty much only into the relative wind, which is totally dependent on the direction ("forward") of flight ("forward slip").

When you use rudder and aileron to keep the nose pointed forward but allow the plane to move sideways through the crosswind, not the relative wind, you are slipping sideways ("side slip").

Or... look at it this way: a forward slip is not used to correct a sideways motion relative to the runway (or intended track), but a side slip is used for just that.

But it's all semantics at this point...I understand why there are two camps.

To many, the fact that what I call a "forward slip" presents the side of the plane to the relative wind means it's a "side slip".

But I'm thinking of which way (relative to the direction of flight)  you're slipping, which IMHO is the most important difference... not the attitude of the nose relative to the direction of flight.
Slipping is a movement lateral to the longitudinal axis of the plane, make no mistake about it... and it is independent of the direction of flight, even when you are slipping "wing forward" just to lose altitude, and it happens to correspond more or less with the direction of flight.

I taken a 60 question practice one before from a book (from 1986) and got a 65%, not bad since half of the charts you were suppose to use were missing. Grin
