  • Slaved directional gyro for use in KCS-305 compass system
  • Typically used in conjunction with KMT-112 flux valve and KA-51A/B slaving accessory
  • With KMT-112 and KA-51A/B this unit will provide heading information for any standard ARINC Autopilot or Flight Director System as well as heading cards on both Pictorial Navigation Indicators (PNI) and RMIs
  • Has dual ARINC type synchro transmitters which are mechanically positioned for alignment by a stepper motor
  • Tracks the true or slaved magnetic heading in 1/4 degree increments
  • Allows manual slaving and monitoring of system's performance through pilot-operated controls
  • 115 vac, 400 Hz
  • TSO'd
  • -02 version available with added Tumble Detect Circuit which is used to cycle back to fast slave and realign the compass magnetic heading when unusual attitude or rates causes large errors

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.

None, they represent the same unit. Original King Radio part numbers were 9 digits. For example, 066-3056-01. During the Bendix and King merger (i.e. Bendix/King), a new part numbering system was created that converted these 9 digit part numbers to 12 digits. Therefore, 066-3056-01 became 066-03056-0001. Despite this numbering change, units that were originally from the King Radio design still have the 9 digit part number format on the unit dataplate. The 12 digit format for King units appears to be used for catalog and internal Honeywell purposes only. Therefore, any unit that has a zero in its third to last number (i.e. XXX-XXXX-X0XX) has a 9 digit part number (i.e. XXX-XXXX-XXX) on its dataplate / ID Plate.
Mod 1 for the KG-102A gyro capsule (P/N 060-0016-00) incorporates mechanical locking devices on the spin motor assembly and bearing end play adjustments. Quite simply, this modification should be incorporated when the gyro requires maintenance since service parts for gyros not containing this mod are no longer available.

The modification itself consists of installing a redesigned outer gimbals assembly and housing cap with a new bearing retainer and lock nut. The old style had glued in bearings.

The parts kit for installing this Mod is not cost prohibitive. However, due to the labor required to install the kit, the parts and labor cost exceed the gyro value in most cases.

Gyro capsules with serial numbers above 21390, KG-102A assemblies S/N 17698+, and KSG-105 assemblies S/N 3642+ should have had Mod 1 incorporated during original manufacturing. On such units, please note that Mod 1 is not marked on the dataplate(s).

In any case, to determine if a KG-102A gyro capsule has Mod 1 incorporated, inspect the gyro can mod chart either on top of the can (if available) or the gyro capsule dataplate underneath the can (3 screws must be removed). Please reference these pictures.

The maximum drift rate for the KG-102A and KSG-105 directional gyro is 1 degree per minute.
In January 1989 Bendix/King changed from a nine digit to a twelve digit part numbering system. The new, larger 12 digit numbers allowed for the inclusion of software version into the last two digits of the part number for certain units in which software changed frequently such as EFIS and TCAS processors. Therefore, the two digits immediately preceding the software version indicate the hardware version of the unit.

Different software versions imply different operational features and/or interface capabilities and software modifications imply software repairs (bug fixes) to insure proper operation of these features and interfaces. Software version upgrades frequently require hardware modifications to the unit. Such hardware modifications accompanying software version upgrades do not necessarily change the hardware version of the unit.

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 75% of the original exchange price. That is, it cannot cost SEA more than 75% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.
