Lateral stability

Lateral stability is achieved through dihedral, sweepback, keel effect and
proper distribution of weight.
The dihedral angle is the angle that each wing makes with the horizontal (see
Wing Geometry).

Lateral Stability: That quality which tends to correct any disturbance out of the plane of symmetry (that is in side-slipping or rolling). An aeroplane is laterally stable when its wings are not easily tilted sideways by external forces.

Lateral stability
Lateral stability refers to roll stability about the longitudinal axis and ailerons provide the means whereby the aircraft is rolled in the lateral plane.

Lateral Stability.-This depends upon the keel surface or total side area of an airplane. The keel surface includes all the struts, wires, wheels, wings, as well as body, against which a side wind can blow.

19.7.2  Attitude: Heading, Pitch, Bank
The term attitude describes the orientation of the airplane relative to the earth. Attitude is specified in terms of three angles: heading, pitch, and bank.

Adds lateral stability.
Anhedral - The tips are lower than the root; the opposite of dihedral.
Gull wing - Sharp dihedral on the inner wing section, little or none on the outer sections.

SPONSON - A short, winglike protuberance on each side of a seaplane to increase lateral stability.
SQUAWK - A four-digit number which is dialed into his transponder by a pilot to identify his aircraft to air traffic controllers ...

The form here shown above is the simplest, the top planes being set at a slight dihedral angle, in order to procure lateral stability.

Dihedral. The positive acute angle between the lateral axis of an airplane and a line through the center of a wing or horizontal stabilizer. Dihedral contributes to the lateral stability of an airplane.

Single float designs are often advantageous to floatplanes as they are able to handle rough seas due to the variety of large and small floats on the aircraft which provides good lateral stability during landing in rough seas.
