air bleed

i. A small hole in the fuel passage between the float bowl and the discharge nozzle of a float carburetor. This air bleed provides a more even mixture over a wide range of airflows to improve atomizing the fuel and reduces the size of the fuel metering force needed. This decreases the amount of restrictions at the venturi.
ii. Compressed air bled from gas turbine engines. It can be used in aircraft pressurization systems, cabin temperature control, boundary-layer control, and deicing and anti-icing systems.
