Any version of the Bendix/King ART-161A is compatible with the EX500 Multi Function Display. The correct version of the EX500 MFD must be ordered from Avidyne compatible with the RDR-160 radar.

As part of our promise to provide the most honest, quality service to our customers, Southeast Aerospace adheres to strict guidelines for certification according to the FAA and Original Equipment Manufacturers (OEM). While most avionics components do not include a prescribed overhaul procedure in the Maintenance Manual, the FAA has set forth guidelines for the cleaning and inspecting of components as referenced in FAR Part 43.2. Therefore, if a component cannot meet the standards of this Federal Air Regulation in relation to inspection criteria and cleaning potential then it should not be deemed as Overhauled. Southeast Aerospace does not believe in simply providing words on a tag or maintenance release to represent the condition of a component. SEA stands behind the work and service followed through with each and every FAA 8130-3 maintenance release it provides.

The IN-132A and IN-152A monochrome indicators are compatible with all versions of the ART-161A. The IN-232A, IN-2026A, and IN-2028A color indicators are compatible with -6105 thru -6108 ART-161A versions. The IN-1102A, IN-1202A/B monochrome and IN-2021A, IN-2027A color indicators are also compatible for testing only with scan disabled.

Weather radar transceivers use a magnetron which is basically a cathode emission device. The magnetron is subject to deteriorization due to aging. Therefore, it is recommended to perform some type of periodic maintenance to detect and correct the effects of aging. This reduces the chance of an in-service failure.

An annual, routine test of the following parameters should made:

- Power output
- Transmitter frequency
- AFC voltage
- Sensitivity (MDS)

Ideally, the test should take place between December and March prior to the peak thunderstorm season.
