Accelerometers (aka G-Meters) are used extensively in a wide range of applications including Aviation, Marine, Automotive, Military, and others. They are also used  in inertial navigation and guidance systems in airplane and ship autopilots.They help in a better understanding of static, such as gravity, or dynamic forces due to motion or vibration acting on an object.

Original Mechanical and more recent Digital accelerometers, used on civil and military aircraft, measure the instantaneous acceleration (or G-force) of an aircraft and its occupants compared to Earth's standard gravitational pull, in units of "G" (e.g., 1G, 2G). They enable pilots to monitor flight conditions, maintain safety, or practice aerobatics or combat maneuvers. Made by different manufacturers, they are offered as non-certified instruments, for use on  experimental and homebuilt aircraft, or certified products, installed on civil transport an military aircraft.

Mechanical accelerometers, included in this listing, use traditional components like proof masses, springs, and damping to measure acceleration based on displacement, offering high accuracy and durability for specific applications like flight stabilization and weapons communication. They are often of larger size and more expensive. Digital accelerometers, separately listed, are often Micromachined Micro-electromechanical (MEMS) systems, integrating sensors with microelectronic circuits for smaller size, lower cost, and high precision, making them ideal for flight stabilization, AHARS, and autopilot systems.

The choice of an accelerometer depends on the application's need for accuracy, size, cost, and resistance to harsh environments. 

Please consult the Product Description section and the supplied documentation for more information on different brands of our offered accelerometers.

GARMIN GI-106B TSO'd panel-mounted CDI is a high-quality course deviation indicator which includes a VOR/LOC/GPS needle as well as a glideslope needle, that can be hidden and disabled by an installer if the glideslope functionality is not needed. The GI 106B contains LED-lit GPS, NAV and VLOC mode annunciators, for an easy-to-read and modern look. TO/FROM annunciators are also LED, and when invalid, the needles are simply hidden out of the pilot’s view instead of using conventional invalid flags. The GI 106B replaces existing Garmin GI-102A & GI-106A models. It is compatible with the same pinout connections as the legacy GI 102A and GI 106A course deviation indicators, allowing for an easy upgrade path. It also features anti-reflective lenses and LED flood lighting for viewing at night.

HONEYWELL BENDIX KING® KX 155A and KX 165A TSO'd Panel-Mounted NAVCOMM Transceivers update the concept of the combined navigation and communications radio for the 21st century. With such features as programmable comm channels, support for 8.33 kHz Comm tuning (KX 165A model only), GPS QuickTune, multiple operating modes, remote channel increment with flip-flop tuning & a built-in timer, they combine a sophisticated appearance with a number of advanced capabilities including:

Programming of up to 32 Comm channels in a non-volatile memory circuit for ready recall of regularly used frequencies.

Pre-selected frequencies stored in a non-volatile memory circuit.

When interfaced to the KLN 94 GPS, both the standby Comm and Nav frequencies can be selected and remotely tuned from the GPS database.

The KX155A (a KX155 upgrade) provides access to all 200 NAV and 760 COMM frequencies, along with its optional 40-channel glideslope. In addition to its standard use, it incorporates new features including a bearing-to-station mode and a radial-from-station mode, an internal Course Deviation Indicator (CDI) for use when the external CDI is being driven by a GPS receiver, and an elapsed-time and approach timer. The KX 155A system offers 10W minimum COMM transmitter power.

The KX-165A NAV/COMM replaces BENDIX KING® KX-155, KX-155A and KX-165 NAV/COMMs which are discontinued but are still available for outright sale or in exchange for returned customer owned units in USED Serviceable or Overhauled Conditions with FAA 8130-3 Form certification. The letters "SV","OH" and "EX" in the product reference numbers (SKU) indicate the condition/sale terms. 

Very similar to KX 155, the BENDIX KING® KX 165 NAV/COMM additionally incorporates an internal VOR/LOC Converter to directly drive the BENDIX KING®  KI 525A HSI (part of the KCS 55A Compass System). It can also display the current radial from the active VOR instead of the standby NAV frequency. Other features include 10 watts min transmitter power, easy-to-read, bright gas-discharge display, large, self-dimming, microprocessor- controlled gas discharge readouts and solid-state electronic tuning for fast, accurate selection of all 200 NAV and 760 COMM frequencies.

The KX 165A (-0201 model) NAV/COMM is a slide in 8.33 kHz replacement for its predecessors, the KX 155A which is discontinued and KX 165A 25 kHz NAV/COMMs (-0101 model). Completely redesigned, it features programmable Comm channels, support for 8.33kHz Comm tuning, GPS Quick-Tune, multiple operating modes, remote channel increment with flip-flop tuning and a built-in timer.

Mounting racks, connectors and manuals  for the installation of the NAV/COMMs are also offered.
