Y OF AERONAUTICAL TERMS. Aerodrome.--Literally a machine that runs in the air. Aerofoil.--The advancing transverse section of an aeroplane. Aeroplane.--A flying machine of the glider pattern, used in contra-distinction to a dirigible balloon. Aeronaut.--A person who travels in the air. Aerostat.--A machine sustaining weight in the air. A balloon is an aerostat. Aerostatic.--Pertaining to suspension in the air; the art of aerial navigation. Ailerons.--Small stabilizing planes attached to the main planes to assist in preserving equilibrium. Angle of Incidence.--Angle formed by making comparison with a perpendicular line or body. Angle of Inclination.--Angle at which a flying machine rises. This angle, like that of incidence, is obtained by comparison with an upright, or perpendicular line. Auxiliary Planes.--Minor plane surfaces, used in conjunction with the main planes for stabilizing purposes. Biplane.--A flying-machine of the glider type with two surface planes. Blade Twist.--The angle of twist or curvature on a propeller blade. Cambered.--Curve or arch in plane, or wing from port to starboard. Chassis.--The under framework of a flying machine; the framework of the lower plane. Control.--System by which the rudders and stabilizing planes are manipulated. Dihedral.--Having two sides and set at an angle, like dihedral planes, or dihedral propeller blades. Dirigible.--Obedient to a rudder; something that may be steered or directed. Helicopter.--Flying machine the lifting power of which is furnished by vertical propellers. Lateral Curvature.--Parabolic form in a transverse direction. Lateral Equilibrium or Stability.--Maintenance of the machine on an even keel transversely. If the lateral equilibrium is perfect the extreme ends of the machine will be on a dead level. Longitudinal Equilibrium or Stability.--Maintenance of the machine on an even keel from front to rear. Monoplane.--Flying machine with one supporting, or surface plane. Multiplane.--Flying machine with more than three surface planes. Ornithopter.--Flying machine with movable bird-like wings. Parabolic Curves.--Having the form of a parabola--a conic section. Pitch of Propeller Blade.--See "Twist." Ribs.--The pieces over which the cloth covering is stretched. Spread.--The distance from end to end of the main surface; the transverse dimension. Stanchions.--Upright pieces connecting the upper and low
