Gascolator
A gascolator, also known as a ''main line strainer'', ''sediment bowl'' or ''fuel strainer'', acts primarily as a fuel drain for water and small particles of sediment and is usually found at the lowest point of an aircraft's fuel system. The gascolator is located below the level of the aircraft's carburetor and fuel tanks and on light aircraft is commonly located on the front of the firewall, as low as possible. There are two types of gascolators: those tapped for a primer port and those without. If equipped with a primer port the aircraft fuel primer will take its fuel supply from the gascolator, used for engine starting. Gascolators are susceptible to the effects of heat from the co-located engine and exhaust components, which can cause fuel vapourization in the gascolator and vapour lock problems. This usually manifests itself as a partial power loss in cruise flight Cruise is the phase of aircraft flight that starts when the aircraft levels off after a climb, until it begin ...

Aircraft Fuel System
An aircraft fuel system allows the crew to pump, manage, and deliver aviation fuel to the propulsion system and auxiliary power unit (APU) of an aircraft. Fuel systems differ greatly due to different performance of the aircraft in which they are installed. A single-engine piston aircraft has a simple fuel system; a tanker (such as the KC-135), in addition to managing its own fuel, can also provide fuel to other aircraft.Taylor 1990, p. 164. Fuel is piped through fuel lines to a fuel control valve (usually known as the fuel selector). This valve serves several functions. The first function is to act as a fuel shut-off valve. This is required to provide the crew with a means to prevent fuel reaching the engine in case of an engine fire. The second function is to allow the pilot to choose which tank feeds the engine. Many aircraft have the left tank and right tank selections available to the pilot. Some Cessna airplanes feed only from both tanks; and many have the option to feed fro ...

Carburetor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...

Light Aircraft
A light aircraft is an aircraft that has a maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308. Aviation Supplies & Academics, 1997. Light aircraft are used as utility aircraft commercially for passenger and freight transport, sightseeing, photography, and other roles, as well as personal use. Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft B200 Super King Air. Uses Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flight instruction. The majority of personal aircraft are light aircraft, the most popular in history being the Cessna 172, and most popular in modern history being the Cirrus SR22 and Robinson R44. Larger light aircraft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firewall (construction)
A firewall is a fire-resistant barrier used to prevent the spread of fire. Firewalls are built between or through buildings, structures, or electrical substation transformers, or within an aircraft or vehicle. Applications Firewalls can be used to subdivide a building into separate fire areas and are constructed in accordance with the locally applicable building codes. Firewalls are a portion of a building's passive fire protection systems. Firewalls can be used to separate-high value transformers at an electrical substation in the event of a mineral oil tank rupture and ignition. The firewall serves as a fire containment wall between one oil-filled transformer and other neighboring transformers, building structures, and site equipment. Types There are three main classifications of ''fire rated walls'': fire walls, fire barriers, and fire partitions. *A ''firewall'' is an assembly of materials used to separate transformers, structures, or large buildings to prevent the s ...

Experimental Aircraft Association
The Experimental Aircraft Association (EAA) is an international organization of aviation enthusiasts based in Oshkosh, Wisconsin, United States. Since its inception, it has grown internationally with over 200,000 members and nearly 1,000 chapters worldwide. It hosts the largest aviation gathering of its kind in the world, EAA AirVenture Oshkosh. History The EAA was founded in 1953 by veteran aviator Paul Poberezny along with other aviation enthusiasts. The organization began as more or less a flying club. Poberezny explains the nature of the organization's name, "Because the planes we flew were modified or built from scratch, they were required to display an EXPERIMENTAL placard where it could be seen on the door or cockpit, so it was quite natural that we call ourselves the "Experimental Aircraft Association". The EAA was incorporated in Wisconsin on 22 March 1955. Homebuilding is still a large part of EAA, but the organization has grown over the years to include almost every ...

Cruise Flight
Cruise is the phase of aircraft flight that starts when the aircraft levels off after a climb, until it begins to descend for landing. Cruising usually consumes the majority of a flight, and it may include changes in heading (direction of flight), airspeed and altitude. Commercial or passenger aircraft are usually designed for optimum performance around their cruise speed ( VC) and cruise altitude. Factors affecting optimum cruise speed and altitude include payload, center of gravity, air temperature, and humidity. Cruise altitude is usually where the higher ground speed is balanced against the decrease in engine thrust and efficiency at higher altitudes. A typical cruising airspeed for a long-distance commercial passenger aircraft is approximately . The typical cruising altitude for commercial airliners is . The speed which covers the greatest distance for a given amount of fuel is known as the maximum range speed. This is the speed at which drag is minimised. For jet aircraft ...
