What is a Diluter Demand Oxygen Regulator?

A Diluter Demand Oxygen Regulator (REGULATOR,OXYGEN,DILUTER DEMAND) is a regulator which incorporates a mechanism to mix air with oxygen up to predetermined altitudes. At the predetermined altitude the regulator automatically delivers pure oxygen.

What is an Oxygen Mask?

An Oxygen Mask (MASK,OXYGEN) is a device consisting of a facepiece which partially covers the face, having a breathing tube and a coupling for connecting to a regulated supply of oxygen. The device may be of the rebreathing type or of the demand type and may be used for rescue operation or to supply the wearer with oxygen when flying at high altitudes. It may include regulating device(s) but does not include oxygen cylinder(s). Excludes MASK, ORONASAL.

What is an Aircraft Air Conditioning-Heating Duct Assembly?

An Aircraft Air Conditioning-Heating Duct Assembly (DUCT ASSEMBLY,AIR CONDITIONING-HEATING,AIRCRAFT) is a hollow body used to transport air to various parts of the aircraft for the purpose of heating, cooling, pressurizing, de-icing, and the like. It may include flange(s), bracket(s), and the like for mounting purposes. Excludes pipes used in aircraft exhaust systems and pipes used in non-aircraft applications. Excludes PIPE, EXHAUST and PIPE, AIR CONDITIONING-HEATING.

What is an Aircraft Air Temperature Electrical-Electronic Control Box?

An Aircraft Air Temperature Electrical-Electronic Control Box (CONTROL BOX,ELECTRICAL-ELECTRONIC,AIRCRAFT AIR TEMPERATURE) is a metal inclosure which includes mounts and protects any quantity and/or combination of electrical/electronic devices such as resistors, relays, potentiometers, receptacles, rectifiers, bridge networks and the like. If electrical, it may not contain electronic tubes and/or resistors. It may have adjustment controls. Designed to produce an electrical signal to control air temperature for an aircraft cabin, cockpit, window, windshield and other comparments for the purpose of anti-icing, defogging or heating.

What is an Aircraft Thermal Insulation Pipe Covering?

An Aircraft Thermal Insulation Pipe Covering (INSULATION PIPE COVERING,THERMAL,AIRCRAFT) is an item composed of one or more materials, molded, compressed, and/or baked into a rigid covering of irregular shapes and sizes. It is designed to cover air ducts and/or air duct fittings used in air conditioning, heating, cooling, pressurizing, de-icing systems and in hydraulic systems to restrict the dissipation of heat. It may completely or partially encase the item for which designed. It may be furnished with or without fillers, cement, and/or separate or attached accessories for installation, (excluding flexible air duct covering and rigid pipe and pipe fitting coverings used in construction and building materials). Excludes INSULATION BLANKET,THERMAL,AIRCRAFT; INSULATION PIPE FITTING COVERING,THERMAL; and INSULATION SLEEVING,THERMAL.

What is an Aircraft Thermal Insulation Blanket?

An Aircraft Thermal Insulation Blanket (INSULATION BLANKET,THERMAL,AIRCRAFT) is a flexible item composed of one or more kinds of fibers prefabricated into various shapes and sizes. It may have a vapor barrier and is covered on one or both sides with a jacket material such as vinyl or other sheet material. It may have mounting provisions such as holes or snaps to facilitate installation. It is designed to cover air conditioning, heating, cooling, pressurizing, de-icing components and air ducts to prevent or reduce the transfer of heat. Excludes rigid air duct coverings and insulation material supplied in flat sheets or rolls. Excludes INSULATION PIPE COVERING,THERMAL,AIRCRAFT and INSULATION BLANKET,THERMAL.

What is an Aircraft Heating And Ventilating Air Diffuser?

An Aircraft Heating And Ventilating Air Diffuser (DIFFUSER,AIR,AIRCRAFT HEATING AND VENTILATING) is a device for installation in aircraft, used in varying designs to effect the proper distribution of ventilated or heated air to assure temperature equalization, or for the defrosting and de-icing of aircraft glass surfaces.

What is an Aircraft Air To Air Heat Exchanger?

An Aircraft Air To Air Heat Exchanger (HEAT EXCHANGER,AIR TO AIR,AIRCRAFT) is a heat transfer device designed to lower compressed air temperature to an acceptable level by passing it through tubes and flowing ducted ram air over the tubes, heat of the compressed air is transferred to the ram air reducing the temperature. Consists of a sheet metal housing with ram air connection(s) with or without ducts, a tubular type core, inlet and outlet ports. May contain a shutoff valve. Normally used in aircraft air conditioning and/or air induction systems.

NATO Supply Class 1660 is a classification for Aircraft Air Conditioning, Heating, and Pressurizing Equipment. It falls under NATO Supply Group 16, which is dedicated to Aerospace Craft Components and Accessories.

This supply class includes various equipment and systems that are essential for maintaining the desired temperature, humidity, and pressure conditions inside an aircraft. Some examples of the equipment covered in this class are air conditioning units, heating systems, and pressurization systems.

These components play a crucial role in ensuring the comfort and safety of passengers and crew members during flight. They help regulate the temperature and humidity levels inside the aircraft cabin, ensuring a pleasant environment for everyone on board. Additionally, pressurization systems help maintain the appropriate air pressure inside the aircraft, especially at high altitudes, to ensure the well-being of passengers and crew.

NATO Supply Class 1660 is specifically focused on the equipment and systems related to air conditioning, heating, and pressurization in aircraft. It is an important classification within NATO's supply system, as it helps in the standardization and categorization of aerospace craft components and accessories.
