1.7CONTINUED AIRWORTHINESS INSTRUCTIONS 1.7.1 Equipment
The instructions for continued airworthiness given in the TC or STC approvals for this product supplements or supersedes the instructions for continued airworthiness in this manual.
Most Honeywell products are designed and manufactured to allow "on condition maintenance". On condition maintenance is described as follows; There are no periodic service requirements necessary to maintain continued airworthiness. No maintenance is required until the equipment does not properly perform its intended function. When service is required, a complete performance test should be accomplished following any repair action. Consult the appropriate unit Maintenance/Overhaul Manual for complete performance test information.
14 CFR Part 25.1529 Instructions for Continued Airworthiness is met per the following instructions:
A.The removal of the equipment is on the condition of failure. There is no re- quired maintenance.

INSTALLATION
2.1 GENERAL
This section contains the suggestions and information to consider before installation of the KNI 582 Radio Magnetic Indicator into the aircraft. Close adherence to these suggestions will assure optimum performance from the equipment.
2.2 UNPACKING AND INSPECTING EQUIPMENT
Exercise extreme care when unpacking the equipment. Make a visual inspection of the unit for evidence of damage during shipment. If a claim for damage is to be made, save the shipping container to substantiate the claim. The claim should be promptly filed with the transportation company. It would be advisable to retain the container and packing material after all equipment has been removed, in the event that equipment storage or reshipment should become necessary. The KNI 582 RMI installation will conform to standards designated by the customer, installing agency and existing conditions as to unit location and type of installation.
2.3KNI 582 RMI INSTALLATION
A.Plan a location on the aircraft panel that is clearly visible to the pilot with the least practicable deviation from his normal position and from his line of vision when he is looking forward along the flight path.
B.Make certain that clearance is available for the installation of the cables and connectors, and also that normal vibration does not cause the unit to bump against other equipment cases.
C.If an instrument hole that meets the installation requirements is not available, cut a 3" ATI hole per Figure
D.The KNI 582 RMI may be secured in place from front or behind the panel.
2.4POST INSTALLATION CHECK
These are tests designed to show that the KNI 582 RMI is functioning accurately under broadly nominal conditions.
A.Compass Card Accuracy
1.With the aircraft on a known magnetic heading, this heading ??2?? should be under the lubber line of KNI 582 RMI.
KNI 582
2.The above step should be repeated for at least one additional heading 90?? from the first.
B.ADF Accuracy
1.Depending on the application, the KNI 582 RMI can be tested for either DC SIN/COS ADF or X, Y, Z, ADF by tuning in a station on the appropriate ADF.
2.In the DC SIN/COS Mode the needles should position the direction of the station +5??. Repeat for at least one more station.
3.Repeat Step 2 for X, Y, Z, ADF +5??.
C.VOR Accuracy
1.Depending on the application, the KNI 582 RMI can be tested for either OBI DIGITAL VOR, COMPOSITE VOR, or OBI SIN/COS VOR by tuning in a station on the appropriate VOR.
2.In the OBI DIGITAL VOR Mode, the single needle should point to the station +5??. Repeat for at least one more station.
3.Repeat Step 2 for COMPOSITE VOR +5??.
4.Repeat Step 2 for OBI SIN/COS VOR +5??.
D.VOR/LOC Composite Correction Adjustment
If it is necessary to make a VOR/LOC composite needle centering adjustment due to NAV receiver composite error, the KNI 582 RMI pointer can be adjusted externally using the following steps:
1.With a
2.With the NAV receiver tuned to the generator frequency, insert a tuning tool into VOR/LOC composite adjustment hole (refer to Figure
3.Repeat Step 2 for verification of the adjustment for another bearing on the ramp with generator.

SECTION 3
OPERATION
3.1 GENERAL
The KNI 582 RMI display is discussed below:
The KNI 582 RMI repeats magnetic heading information from a directional gyro system. Aircraft heading is read under the lubber line of the KNI 582 RMI.
When an ADF receiver is tuned to a station and the appropriate pointer placed in the ADF mode, the arrow of the pointer indicates the magnetic heading to the ADF station. Thus, if the pilot desires to fly toward the station, he merely turns his aircraft to the magnetic heading indicated by the pointer.
When a VOR receiver is tuned to a VOR station and the appropriate pointer placed in the VOR mode, the arrow of the pointer indicates the magnetic heading to the VOR station. If the KNI 582 RMI is used in an area navigation system, the VOR pointer indicates magnetic heading to the waypoint. Should a localizer frequency be selected or the VOR receiver indicates a flagged condition, the VOR pointer is parked 90?? to the right of the lubber line.
