A small hole in the fuel passage between the float bowl and the discharge nozzle of a float carburetor. Air drawn into the liquid fuel through the air bleed breaks the fuel up into an emulsion, making it easy to atomize and thus to vaporize.
Industry:Aviation
A small hole in the lowest part of an aircraft structure, used to ventilate the inside of the structure and to drain any water which collects in this area.
Industry:Aviation
A small hole punched or drilled in a piece of sheet metal to locate a rivet hole. Pilot holes are smaller than the rivet hole, but are large enough to allow sheet metal fasteners to be used to assemble the parts.
When the parts are assembled and temporarily fastened together, a drill of the proper size for the rivet is passed through both pieces of metal. This method of assembly assures the rivet holes will line up properly.
Industry:Aviation
A small hole, or port, in the skin of an aircraft at a location where the airflow is not disturbed. The airspeed indicator, altimeter, and vertical speed indicator get their reference static air pressure from this port. Some aircraft pick up their static pressure from a combined pitot-static tube.
Industry:Aviation
A small hydraulic shock absorber installed between the nose wheel fork and the nose wheel cylinder which is attached to the aircraft structure. The piston inside the shimmy damper cylinder is free to move back and forth when it is moved slowly enough to allow fluid to transfer from one side of the piston to the other through a restrictor.
Slow movement of the piston allows the nose wheel to pivot so the aircraft can be steered on the ground. But, the restrictor slows the flow of fluid inside the cylinder and prevents the piston from moving back and forth as fast as it would if the nose wheel were shimmying.
Industry:Aviation
A small indicator light on a piece of electrical equipment illuminated all the time power is supplied to the equipment. Pilot lights are a reminder to turn the equipment off when it is not being used.
Industry:Aviation
A small inverted V (^) used to show the new location of the decimal in multiplication and division problems using decimal fractions.
Industry:Aviation
A small jar located in the vent line of an aircraft battery box. The sump jar used in a lead-acid battery installation contains a sponge saturated with a solution of bicarbonate of soda and water. Acid fumes from the battery pass through the sump jar where they are neutralized to prevent their causing corrosion in the aircraft structure.
The sump jar in a nickel-cadmium battery installation contains a boric acid solution to neutralize the alkaline fumes from this battery.
Industry:Aviation
A small mark painted between a wheel and a tube-type tire. The mark is half on the tire and half on the wheel. If the mark on the tire is not lined up with the mark on the wheel, it shows that the tire has slipped on the wheel. When a tire slips, the valve in the tube is likely to be damaged, and the tire should be removed from the wheel and the tube examined.
Industry:Aviation
A small metal collar, usually having a hexagonal (six-sided) shape. The hole in the nut is threaded so that it can be screwed onto a bolt. Bolts and nuts are used to fasten two or more pieces of material together. The bolt is installed in holes drilled through the pieces, and a nut is screwed onto the bolt to clamp the pieces together.
