3.3
MOUNTING THE MD41-( )
Plan a location in the aircraft for the MD41-( ) to be mounted as close to the pilot’s field of view
as possible. The preferable location is near the HSI/CDI that will be displaying the navigation
information. Avoid mounting close to heater vents or other high heat sources. Allow a clearance
of at least 3 inches from back of unit for plug removal.
The indicator is secured in place behind the panel since it is designed for rear mount only. Make a
panel cutout as shown in Figure 3-2. Secure the indicator in place with two 4-40 x 3/8 flat head
phillips screws.
3.4
INSTALLATION LIMITATIONS
Wire the aircraft harness according to figure 3-3. Use at least 24 AWG wire for all connections.
Avoid sharp bends and routing cable near high energy sources. Care must be taken to tie the
harness away from aircraft controls and cables. Normal installation techniques should be applied.
Also see equipment limitations, section 1.2.6.
