The engine was moved forward 100 mm (4 in) to improve longitudinal stability.

For details, see the section on longitudinal stability below.

These changes improved longitudinal stability, especially when the aircraft was fully loaded.

A 1/4-inch area in the stagger will make a very considerable difference to the longitudinal stability.

The aerodynamic center is the conceptual starting point for longitudinal stability.

It proved to have poor longitudinal stability and the powerplant itself still had a number of problems.

It suited him, as I remember, except for the longitudinal stability ó he wanted more of that.

Longitudinal stability could be ensured or improved by minimizing the latter effect.

The tailplane is mainly a trimmer rather than for longitudinal stability.

These revealed a number of problems including poor handling, insufficient longitudinal stability and significant changes in trim as engine power was changed.

The results were unfavorable, indicating poor longitudinal stability at high angles-of attack.

About four hours after the beginning of the fire the boat suddenly lost longitudinal stability, took on a steep down-bubble, and sank.

This phenomenon involved a loss of longitudinal stability of the airframe.

The aircraft was test flown successfully, however,the airplane showed signs of inadequate longitudinal stability.

The outer wingpanel dihedral was increased by one degree to increase longitudinal stability.

The Polikarpov had insufficient longitudinal stability and it was impossible to fly the aircraft "hand off".

Advantages of the tandem-rotor system are a larger center-of-gravity range and good longitudinal stability.

Flight testing revealed problems with the harmonization of controls and marginal longitudinal stability.

The two major problems that the Soviet ekranoplans faced were poor longitudinal stability and a need for reliable navigation.

Most successful aircraft have positive longitudinal stability, providing the aircraft's center of gravity lies within the approved range.

"This is when I have the pleasure of meeting you, my dear," said Longitudinal Stability.

Then, in order to secure a sufficiency of longitudinal stability, it is necessary to set the forward stabilizer at about 15 degrees.

The gyroscopic action of a rotary engine will affect the longitudinal stability when an aeroplane is turned to right or left.

A Su-7U modified with canards and a longitudinal stability augmentation system.
