- Definition downslope of an aircraft's wings from its fuselage Reference "COM-EN, based on:DAT Wiki > Cathedral (aerodynamics). http://www.datwiki.net/page.php?id=1549&find=cathedral%20(aerodynamics)&searching=yes [4.1.2012]"
- Comment The wings of an airplane, as they are viewed from the front, are not usually straight; they normally angle upward from the center. This upward angling is called positive dihedral, and it improves the stability of the airplane. However, when maneuverability is more important than stability, as it is on some military fighters and acrobatic airplanes, the wings are set with negative dihedral (cathedral). The wings angle downward from the center. Cathedral decreases the stability of an airplane and makes it more maneuverable.
