And it was only when I went looking for a gage with a ball and saw
none that I learnt (from the captain) that, "Every turn on an aircraft
is a coordinated turn". Wonder why John Denker has written a piece on
coordinated turns at all...

I'm sure that he meant to say "in that aircraft" and not aircraft
in general.

Most, if not all large swept wing aircraft incorporate a "yaw damper"
to prevent an aerodynamic phenomenon called "dutch roll", a see-sawing
back-and-forth of the nose of the aircraft. The yaw damper controls
the rudder independantly of the pilot using gyros and hydraulic controls.
Because it dampens the dutch roll yaw, it also keeps yaw near zero at
all other times....and the ball stays in the middle even in turns.

Not so fortunate in propeller driven general aviation aircraft...
in turns, the pilot must use the rudder controls to keep the a/c
from yawing.
