The FLYdat has been specially developed by TL ELEKTRONIC for BRP-ROTAX® Aircraft Engines for indicating and storing of engine operation data. The unit  is furnished with 8 sensor input ports, which can be occupied variably according to engine type.

The operating data is permanently compared with the engine specific operating limit. If the signalled operating data exceeds the stored operating limit, the FLYdat will warn the pilot. In addition all the input ports are equipped with a maximum alarm, responding when picked-up value is equal or above the stored limit. The FLYdat keeps the pilot informed on the following actual readings. Besides the topical data, the FLYdat shows also the hours of operation.

•  Engine speed

•  Cylinder head temperature (CHT)

•  Exhaust gas temperature (EGT)

•  Ambient air temperature (not on engines 912 / 914)

•  Temperature of cooling water (only on engines 582 UL, 618 UL)

•  Oil temperature and oil pressure (only on engines 912 / 914)

The TL ELEKTRONIC FLYdat is supplied with a standard configuration. With the standard configuration all trigger levels for warning- and alarm system are set to the maximum of the measuring range.

Configuration is available for the following BRP-ROTAX® engine types: 447 UL SCDI, 503 UL DCDI, 582 UL DCDI, 618 UL DCDI, 912 DCDI series, 914 DCDI series, Standard

By configuration of the TL ELEKTRONIC FLYdat, the engine type, engine number, hour of operation, temperature unit and the respective engine limits are programmed.

The TL ELEKTRONIC FLYdat unit and parts are no longer offered as ROTAX Part Numbers. These part numbers are provided for reference only.  In addition, aircraft engine  parts are subject to changes from time to time. Some parts may be no longer available or replaced by others with different part numbers. Listed engine parts do not imply their current availability or suitability for your engine application.

The HONEYWELL BENDIX KING® KI 525A HSI is a pictorial navigation indicator used in the KCS-55A compass system which also includes KG-102A Directional Gyro, KMT-112 Magnetic Azimuth Transmitter (flux valve), KA-51B Slaving Control & Compensator Unit and optionally KA 52/KA 57 Autopilot Adapters. It was a popular avionics upgrade for light aircraft until the advent of the Sandell electronic HSI and, more recently, glass-cockpit systems from Garmin, Aspen and others. This indicator combines the display functions of both the standard directional gyro and the course deviation indicator offering the pilot a single view of the horizontal navigation situation. It greatly simplifies course orientation, interception, and tracking resulting in less work from the pilot. Internally lighted, the KI 525A operates at 14 or 28 VDC.

The HONEYWELL BENDIX KING® KI 525A HSI is available in different models to serve application requirements:

- with bootstrap heading synchro to provide source of slaved heading information for any device, such as an autopilot

- with glideslope needle damping for use in high vibration environments such as helicopter

- capable of operating at either 30Hz or 400Hz

- capable of operating at 14 or 28VDC and 5 volt operation

Like other KCS 55A compass system components, the  KI 525A indicator 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).

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 SIRS "Navigator" magnetic compass delivers extremely accurate readings due to its fully integrated, 4 magnet correction facility.  It has the same features as the "Pegasus", but is mounted with a fully adjustable bracket that allows attachment to a variety of positions including the glare-shield or the windshield.
