In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

Yes. The KA-51B slaving accessory used in the KCS-55A compass system may be located remotely. An optional compensator kit is available for installations where the installer wants to use a different switch/meter arrangement. The compensator kit includes a compensator assembly which is basically the back half of the KA-51B. The kit also includes a mating connector and a special remote mounting plate for the compensator assembly. Mounting the compensator remotely allows the installer to easily adjust the E/W & N/S compensation without removing the KA-51B from the panel.
No. The KCS-55A does not require any adapters for interface to S-Tec autopilots systems.
No. All KCS-55A systems are slaved systems with incorporation of the KMT-112 flux detector.
For the most part, the system wiring and connections are the same. The only wiring change needed pertains to the HSI unit. The KI-525 contained a Power flag instead of the standard Heading (HDG) flag as with the KI-525A. Therefore, pin P must be added to the existing KI-525 harness for the HDG flag in the KI-525A.

If the HSI is being upgraded to the -07 version of the KI-525A, then there is another pin that must be jumpered. Please see the KI-525A FAQ for more information on this matter.

The original KCS-55 system contained the KA-51A slaving accessory. This still can be utilized in the KCS-55A however it is recommended to upgrade to the KA-51B due to the age and lack of availability of service parts for the KA-51A. If the KA-51B is added, then a connector change would be required.

The Century NSD-360A is vacuum driven while the KCS-55A is electrically driven.

The KA-51A is the slaving control that was originally part of the KCS-55A compass system. It has since been replaced by the KA-51B, mainly due to durability problems with the faceplate mounting holes. Since introduction of the KA-51B, Bendix/King has ceased production of replacement parts for the KA-51A, thus making it virtually unrepairable.

Please note that the KA-51B is not a direct replacement for the KA-51A, but is an easily performed upgrade that only requires replacement of the connectors.

The KG-102A can supply 400 Hz power and eliminate the need for an additional inverter. Pins little p and t on the KG-102A provide the output. Please note that the KG-102A has a 5 VA maximum of 26VAC 400Hz power available. If more than 5VA is required, then an external inverter would be necessary.
To upgrade from the KCS-55 to the KCS-55A, the KI-525 and KG-102 must be changed to the KI-525A and KG-102A. The mating connectors and racks are the same. However, some pins in the KI harness must be changed to accommodate the KI-525A.

Southeast Aerospace highly recommends upgrading to the KCS-55A. The old KI-525 and KG-102 are not supportable or serviceable. Investing in the more modern KCS-55A system will provide you with a compass system that includes warranty and support for years to come.
