Additional Information for Aircraft Alarm and Signal Systems Additional Information for Aircraft Alarm and Signal Systems

NATO Supply Class 6340 is a classification within NATO Supply Group 63, which is dedicated to Alarm, Signal, and Security Detection Systems. Specifically, Class 6340 focuses on Aircraft Alarm and Signal Systems.

Aircraft Alarm and Signal Systems are essential components of aircraft safety and security. They are designed to detect and alert pilots and crew members about potential threats, malfunctions, or emergencies during flight operations. These systems play a crucial role in ensuring the safety of both the aircraft and its occupants.

Within NATO Supply Class 6340, you can find various types of alarm and signal systems specifically designed for aircraft use. These systems may include but are not limited to:

1. Warning and Alert Systems: These systems provide visual, audible, or tactile warnings to the flight crew in case of critical situations such as engine failures, fire, smoke, or other emergencies.

2. Communication Systems: These systems facilitate communication between the aircraft and ground control, as well as between different crew members on board. They may include intercom systems, radio communication equipment, and emergency distress beacons.

3. Navigation and Positioning Systems: These systems help the aircraft determine its position, altitude, and heading accurately. They may include instruments such as altimeters, GPS receivers, and attitude indicators.

4. Anti-Collision Systems: These systems are designed to detect and prevent collisions with other aircraft or obstacles. They may include radar-based systems, transponders, and traffic alert and collision avoidance systems (TCAS).

5. Emergency Locator Systems: These systems aid in locating an aircraft in distress or after a crash. They typically include emergency locator transmitters (ELTs) that emit distress signals to facilitate search and rescue operations.

It's important to note that NATO Supply Class 6340 encompasses a wide range of alarm and signal systems specifically tailored for aircraft use. The classification ensures that these systems meet NATO's standards and requirements for military aviation operations.

If you need more specific information about a particular system or product within NATO Supply Class 6340, it would be helpful to provide additional details or specifications.

Supply Items Included in Federal Supply Class 6340 Supply Items Included in Federal Supply Class 6340

What is an Annunciator? 683 Items
An Annunciator is a signaling apparatus which operates electromagnetically and serves to indicate visually, or visually and audibly, whether a current is flowing, has flowed, or has changed direction of flow in one or more circuits. It is usually employed in connection with alarms, electric bells, or buzzers. See also ALARM (as modified).
What is an Indicator Light? 198 Items
An Indicator Light (LIGHT,INDICATOR) is a light, with mounting facilities furnished, designed to convey information of a specific nature concerning the circuit in which inserted. Must include or provide for the use of a lens as a part of it. For items without a lens, see LAMPHOLDER, and also see LIGHT (1), PANEL.
What is an Alarm Control? 201 Items
An Alarm Control (CONTROL,ALARM) is an automatic electrical, electromechanical, or electronic device which generates and/or controls the energy which actuates electrical alarms such as bells, horns, sirens, buzzers, lights, and which does not in itself contain the actual alarm. If complete with alarm, the device takes the name of the type of alarm, such as ALARM (as modified).
What is an Indicator Light Assembly? 29 Items
An Indicator Light Assembly (LIGHT ASSEMBLY,INDICATOR) is an item designed to convey information of a specific nature concerning the circuit in which inserted. Consists of two or more LIGHT, INDICATOR.
What is an Alarm-Monitor Group? 34 Items
An Alarm-Monitor Group is a collection of items, which provide alarm and monitor functions.
What is an Alarm-Monitor? 90 Items
An Alarm-Monitor is an item which performs the dual function of presenting operational information from other components or sets, and provides an alerting signal upon departure from normal operating conditions.
What is a Fire Detector System Sensing Element? 710 Items
A Fire Detector System Sensing Element (SENSING ELEMENT,FIRE DETECTOR SYSTEM) is an item consisting of a pair of electrical conductors imbedded in a semiconductor material, having a negative temperature coefficient of resistance which is tightly encased in a suitable metallic tube. The ends of the assembly are terminated for adaption in a fire detector system.
What is a Landing Gear Audible Alarm? 34 Items
A Landing Gear Audible Alarm (ALARM,AUDIBLE,LANDING GEAR) is an electronic signal used on aircraft to warn the pilot of an unsafe landing gear condition. It is furnished by the injection of interrupted tones in the pilot's headset when the throttle is retarded with gear not down and locked.
What is an Ice Detector? 115 Items
An Ice Detector (DETECTOR,ICE) is a device designed to detect icing conditions and provide an ice warning signal when the ice accretion reaches a preset level. The device may also transmit an electrical signal which can be used to control operation of the ice protection system.
What is an Opaque Particle Sensor? 37 Items
An Opaque Particle Sensor (SENSOR,OPAQUE PARTICLE) is a device designed to detect the presence of predetermined amounts of smoke, dust, and the like, within the measuring area. The presence of any of these substances causes a change in the output signal of the device, which relays a warning message back to a central panel. The device itself does not provide any audible or visible output, or analyze chemical content. Excludes ALARM, SMOKE, AUTOMATIC.
What is a Pilot Warning Alarm Set? 114 Items
A Pilot Warning Alarm Set (ALARM SET,PILOT WARNING) is a complete electrical warning unit specifically designed to provide an aural message/warning through pilot's earphones and/or visual message on pilot's heads-up visor display or a control panel indicating an unsafe aircraft attitude, such as: altitude, fire, canopy, pressurization, engine and/or rotor RPMs, etc. Item does not provide facilities for bells, buzzers, horns, sirens and/or lights. Excludes ALARM SET, PERSONNEL HAZARD.
What is a Heat Detector? 107 Items
A Heat Detector (DETECTOR,HEAT) is a device designed to open or close an electrical circuit upon a pre-set ambient temperature fluctuation. Excludes ALARM, SMOKE, AUTOMATIC.
What is a Ground Proximity Warning Computer? 66 Items
A Ground Proximity Warning Computer (COMPUTER,WARNING,GROUND PROXIMITY) is a computer preprogrammed to determine the distance of an aircraft from the surface of the earth and warn the pilot with an audible alarm. See also COMPUTER, TERRAIN CLEARANCE.
