I'll answer your last question (topic) first, since it is also related
to your first question (topic) about 3 point landings.

PJ, note that Ramapriya's questions deal primarily with jet transports.

Wheel barrowing (also known as porpoising)

Wheel-barrowing and porpoising are NOT the same. Wheel-barrowing always
results from a too-high speed on the ground and the airpane's attitude
remains relatively stable in a nose too-low attitude. Porpoising results
from landing on the nose wheel in a nose-low attitude resulting in the
airplane rebounding into a nose-high attitude and then repeating this
"porpoising" maneuver. Wheel-barrowing can also occur during takeoff
when one attempts to hold the airplane on the ground after normal take-
off speed.


2. If you 'tilt' the wing too much you certain can, and pilots have
had engine strikes.

Jetliner takeoff wings-level to avoid this situation.

The same can be said for not having enough rudder to keep the nose
going straight down the runway.

That's what the nose-wheel steering is for.

3. You slip the aircraft by cross controlling.

Never done in jetliners...too uncomfortable for the passengers.
