Many problems beset the project, including the chance of a Dutch roll.

This can lead to a Dutch roll in reverse.

The aircraft entered into a situation known as a Dutch Roll.

This in turn helps reduce roll-yaw coupling and any tendency to Dutch roll.

They suffered from an effect known as "Dutch roll" that made them more difficult to turn and tended to "hunt" after levelling.

Too much dihedral or sweepback generally causes Dutch roll.

This instability is similar to "Dutch roll".

Some swept-wing aircraft have an unstable Dutch roll.

The Dutch roll is dampened out and the aircraft becomes stable about the yaw axis.

The Dutch roll should therefore be damped.

The 747 was found to be largely immune to "Dutch roll", a phenomenon that had been a major hazard to the early swept-wing jets.

It proved to have serious aerodynamic flaws and structural problems causing Dutch Roll at speed.

Taking the latter as zero, assuming no effect on the trajectory, for the limited purpose of studying the Dutch roll:

The three dynamic instability modes are pitch (phugoid) oscillation, spiral and Dutch roll.

Following flights revealed a propensity to "Dutch roll" - an alternating yawing and rolling motion.

Since Dutch roll is a handling mode, analogous to the short period pitch oscillation, any effect it might have on the trajectory may be ignored.

After investigation, it was determined that a rudder power control unit malfunction led to a Dutch roll oscillatory instability.

It is usual to design the aircraft with a stable Dutch roll mode, but slightly unstable spiral mode.

In his autobiography, test pilot Johnston describes a Dutch roll incident he experienced as a passenger on an early commercial 707 flight.

In most cases, instructors will try to determine your skill with some fairly simple but revealing activities, like steep turns, Dutch rolls, or lazy eights.

Not recognizing the Dutch roll, the crew used the rudder to stay on course, which exacerbated the instability, leading to an unrecoverable flight condition.

It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis.

The cause of the crash was attributed to the onset of Dutch roll stemming from control instability as induced by flow separation.

Ultimately, the mishap board determined that a rudder system malfunction contributed to development of oscillatory instability, known as "Dutch roll."

The prototypes initially suffered from "Dutch roll", an instability that caused the aircraft to weave in widening "S" turns.
