Anhedral and dihedral refer to the angle of an aircrafts wings in relation to the horizontal plane of the aircraft.
Most aircraft have wings which are angled upward from the wing root. This is called dihedral.
Some aircraft have wings which are angled downward from the wing root. This is called anhedral.
Anhedral refers to the downward slope of an aircrafts wings.
Anhedral is the negative "tilt" of a wing like what is found on a harrier jet. When you look at the wings of a passanger jet liner you see that they are tilted up, this is called "dihedral", anhedral is the opposite of this, with a downward tilt rather than an upward one. Anhedral is usually used to cause an inherent instability to increase the maneuverability of an aircraft.
An anhedral is the downward slope of an aircraft's wing.
Dihedral is the angle between the mounted position of the wings and the horizontal axis. A dihedral allows better in flight stability.
Dihedral usually makes an aircraft more stable in attitude.
Dihedral is the angle that the wing diverges from horizontal. Most planes have a positive dihedral, meaning the wings angle up slightly. This gives the plane stability in flight. Acrobatic and fighter planes tend to have a negative dihedral (wings droop) which allows them to manoeuver quickly.
A dihedral angle is the angle between two intersecting planes. It does not have a specific degree.
An upwards inclination of the wings on lateral axis and an included angle is known as dihedral angle.
The C182 hardly has dihedral, if any. Dihedral is when the wing is kind of a "V" shape. This picture is self explanatory: http://www.littletoyairplanes.com/theoryofflight/images/whyplanesfly/fullsize/10dihedral.jpg
In general terms, in aircraft design dihedral, or a wing angled slightly upwards, contributes to the stability of the aircraft. Wing design has evolved immensely and with almost every new aircraft, new things appear. -Point of example is the upright wing extension many new airliners 'wear' - they figured out that a small amount of air 'slipping off' the wingtip added to fuel consumption. --Look at many fighter aircraft and see absolutely level or even anhedral wings (angled down) - this is because you don't want a fighter to be stable - a fighter pilot would prefer to flip over on his back in a millisecond - and many can ! - I remember the old F-4 Phantom with it's anhedral tail surfaces as being able to do a 'barrel roll' in the time you could blink !
