The HONEYWELL BENDIX KING® KMT 112 is a Magnetic Azimuth Transmitter (aka Flux Detector or  Valve) which senses the direction of the earth’s magnetic field and continuously transmits this information through the slaving circuitry to a directional gyro (such as the HONEYWELL BENDIX KING® KG 102A or KSG 105 slaved directional gyros). This sensor is mounted remotely, usually in a wingtip, to eliminate the possibility of magnetic interference. The KMT 112 is typically used in HONEYWELL BENDIX KING® KCS 55A and KCS 305 compass systems. The KMT-112 flux valve is a sealed unit and cannot be serviced or have parts replaced. The unit must be replaced when/if it fails.

Like other KCS 55A compass system components, the  KMT 112 transmitter can be furnished in NEW condition or as USED in Serviceable or Overhauled conditions indicated respectively by the letters "SV" and "OH" in the product reference numbers (SKU and  accompanied by the relevant certification (e.g. yellow tag, 8130-3 form). They are also offered as exchanges / trade-ins  for returned customer owned units indicated by the letter "EX" in the SKU.  In the case of an exchange/trade-in option of a customer unit, the  full selling price of the ordered unit is charged and the core credit is refunded or credited towards future orders when our co-operating supplier verifies that the unit is in a reasonable, repairable condition. It is recommended that this option is selected by our customers mainly for upgrades and only in cases when their units are functioning properly at the time removal from the aircraft. In cases when customer units are found by our supplier to be non-repairable, the core deposit shall not be refunded and shipping charges shall apply if customers wish the return of these units to them. 

Installation parts and manuals are sold separately. 

For additional information and technical specifications please refer to the Product Desscription section, the product presentation of the HONEYWELL BENDIX KING® KCS 55A compass system or contact us.

The RAY ALLEN (RAC) RP4 LED position indicator is designed to be installed in the cockpit providing an indication of the servo output shaft position. This indicator supercedes and it is a direct replacement for previous RAC RP3. The RP4 indicator uses ten LED lights to show the position of a actuator output shaft (or position sensor arm). There are also two amber colored LED's, one on each end of the indicator scale, to act as a reference for the green indicator light, especially in dark conditions. The 10 LEDs are the brightest available for superior visibility in sunlight, but can be dimmed for night flight. It can be installed horizontally or vertically. 

The RAC RP4 position indicator is panel mounted using a faceplate and two countersunk, 2-56 x 7/16" screws (two spare finishing screws are included). The distance between the screw holes is identical to the older Ray Allen RP3 LED indicator. Although the faceplate dimensions are identical between the RP3 and RP4 indicators, the panel cutout size is slightly different between the RP3 and RP4. If you are replacing and older unit with a new RP4, you will only need to increase the size of your panel hole. The RP4 faceplate will cover the older RP3 panel hole.The RP4 faceplate measures 1.75"(45 mm) X .75"(19 mm) and it is 1.6"(41 mm) in depth. It is now the standard position indicator included in Ray Allen trim systems, or can be purchased separately for special applications such as a cowl or wing flap indicator.

The RP4 includes a RP4-L1 label (featuring Elev1, Elev2, Ail, Rudder, Flaps). A RP4-L2 label (featuring Cowl Flaps, < >, on/off) is also available and is sold separately. 

NOTE: Labels can only be ordered together with . In ordering these high quality labels please be advised that rocker switches and needle indicators require a large label, LED indicators use a small label. Can be only included in orders of respective RP4 position indicator(s) (not separately).

The AVIASPORT indicators (gauges) are reliable, accurate and solid, combining the accumulated experience of more than twenty years with the latest technology  They have been designed for ROTAX engines and their display areas are divided into red, green and yellow zones in line with Rotax limits. They use a pointer that turns 240º or 320º, providing high resolution. AVIASPORT range of gauges includes CHT, EGT, tachometers, oil and fuel pressure, oil and coolant temperature, fuel level, voltmeters & ammeters and offered with casings of different sizes: 80mm; 57mm and 52mm.

The AVIASPORT fuel pressure gauges  have been designed especially to measure fuel pressure in Rotax® engines 912 and work both with 12V and 24V systems. Unlike mechanical gauges, the AVIASPORT ielectronic gauges use a high precision sensor to be installed close to the engine, preventing fuel lines in the cockpit. These gauges are sold without sending units or as kits with matching senders whenever specified.

TSO'd Electronic Fuel Quantity gauges from UMA INSTRUMENTS (indicated by the letter "T" in the PN) are offered in 1-1/4 in. and 2-1/4 in. sizes for installation in respective panel hole diameters and mounted with (4) 6-32 screws. Smaller 1-1/4 in. instruments can be cluster mounted as close as 11/2” centers utilizing panel space without compromising readability. They can be powered from 14 or 28 volts. Signals are acquired from remote mounted sensors, processed and displayed on black analog dials with white easy to read markings indicating empty to full fuel level. Each gauge uses rugged aircore meter movement for vibration resistance and repeatability. Available in different versions based on their sender type and range. UMA sensors are sold separately.
