slip or skid?

[airpix]

During climbout with the wings level and no rudder, ball's pegged to the right, is the aircraft in a slip, skid or neither?

A slip

Well, I'd say...if the airplane is not holding a constant heading and the wings are level, then the ball is out because you are in a skidding turn to the left.

Skid is when the ball is outside opposite the direction of turn...I would also agree with Donsa320.

Center the ball with rudder trim. If you ever fly the MU-2 this will become habit. One side on the climb, the other on descent.
So to answer your ? maybe it's a skip or a slid?

Correct, in a turn. I think to answer airpix's question, we need to know if the heading is decreasing, or constant.

Decreasing = skid
Constant = slip

I'd say if the heading is CONSTANT with the wings level and the ball out to the right, then the ball instrument is not installed level. Only two forces can act on the ball...gravity and centrifigal. If there is no TURN then there is no centrifigal. If the wings are level, gravity would center the ball. So...the only way the ball can be out with wings LEVEL is in a skidding turn. (Or the if the ball race is installed cockeyed, <grin>)
Now if you stop that turn with wing down, its a slip. But he says the wings are level. It's a skid. IMHO.

Good info Donsa320. Man you have flown everything

Lets say that a 172 is climbing out with a 15kt crosswind, and you are holding constant heading with level wings (no crab angle, being blown to the left). How would the plane be coordinated then?

I have a feeling that is what airpix meant.

How about centering the ball with your feet, and using the trim to take away the control pressure? Better yet: How about using your feet to never let the ball move from the center as you change power settings?

just deleted a drunk post, keep scrolling.

No Mu-2 time, but the Dash-8 was the same way. It used to drive me up and down the wall to see the person you're flying with (Capts and FO's) yank the power back with their feet flat on the floor, watch their coffee almost spill out the cup as the airplane gets completely uncoordinated, then start tweaking the rudder trim, all while keeping their feet on the floor.

I don't mean to be ranting here, but Jeez that drove me nuts.

slip or skid on climbout

No I'm just wondering what to tell the student on takeoff. Climbing out, wings are level, balls pegged to the right, headings constant. They won't use enough right rudder!! Are they skidding the plane or slipping it?

STEP ON THE BALL, THE PLANE'S IN A _______________?

Yep, Airplane Flying Handbook p 4-5.

Is that chapter 4, page 5? I can't find it.

The WIND has no effect on what the ball instrument is displaying.
