Neither the KNS-80 or KNS-81 Nav Systems contain FM immunity. Likewise, there are no modifications or service bulletins that can be incorporated to achieve FM immunity. However, the KNS-81 can be used in conjunction with KA-155 FM filter to achieve FM immunity. KNS-81 units must have Mod 14 to be compatible with the KA-155. KNS-81 units above serial number 8309 already have this mod incorporated. According to Revision 4 of the KA-155 installation manual, the KNS-80 can be used with the KA-155 filter as well.
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.

The KNS-81 meets TSO C40a (VOR), C36c (LOC), and C34c (Glideslope). The KNS-80 does not meet any TSOs. The VOR/LOC/GS section of the KNS-80 is very similar to that of the KNS-81. The KNS-80 also include integrated DME. The DME section of the KNS-80 is similar to that of a stand-alone KN-64 DME. The KN-64 is not a TSOd DME. Therefore, with the inclusion of the Non-TSO DME, the KNS-80 is not TSOd overall.
It should be noted that although the KNS-80 is not TSOd, it does meet the Area Navigation System specification as per FAA Advisory Circular 90-45A
Although the specific KNS-80 and KNS-81 installation manuals only specify certain King indicators as compatible, there are many different indicators that can be used with these navigation systems. The King installation manuals indicate the following nav indicators as compatible:
(note: the manual does list some much older indicators as well which are obsolete and unsupportable)
In addition, the following indicators will interface and provide the necessary functions for VOR/LOC/GS navigation:
KI-202 (VOR/LOC only)
IND-350 (VOR/LOC only)
IND-350A (VOR/LOC only)
More or less, any "non-converter" indicator should function properly with the KNS-80 and KNS-81. Please note that it is ultimately the responsibility of the installer to verify system performance, functionality, and airworthiness.
