Figure 2-16. FMA Assembly Lifting Fixture Removal
(d) The orientation of the FMA assembly is defined with respect
to the principal axes of the
aircraft.
(e) Attach the FMA to the AIM with screws and flat washers. The AIM is
provisioned with
captive nuts. Refer to the airframe specific kits and assembly for fastener specifications
and required torque. Mounting holes in base are accessed from the top between the
antenna and turntable by rotating the assembly in azimuth.
(f) Remove protective cap from disconnect plug on harness.
1 Visually inspect connector and make sure that there are no debris in cavities.
2 Visually inspect the center conductor and verify that it is still straight and the finish
is intact.
(2) FMA Bonding Requirements
(a) Install one end of bonding straps to AIM at labeled bo
nding points with screw and
washers.
(b) Install the other end of bonding straps to bonding points on
the FMA base. Refer to the
airframe specific kits and assembly for fastener specifications and required torque.
Refer to Figure 2-10 for the FMA ground strap connection.
(3) Waveguide and RF Coax Interconnection to FMA Assembly
(a) Waveguide and RF coax interconnect designs are aircra
ft specific. Consult aircraft
specific SDIM for detailed installation instructions.
(b) Remove protective cap on FMA J4 (2.92 mm female coax) and FMA J3. Connect K-type
disconnect plug to K-
type disconnect receptacle J4 on the FMA. Connect the WR34
waveguide assembly to the FMA receptacle J3
(4) KRFU Installation Location
(a) The KRFU install location is airframe specific.
(b) The KR
FU can be installed inside the aircraft or external to the aircraft under the
radome. Honeywell r
ecommends that the KRFU is installed external to the aircraft,
under the radome.
(c) When the KRFU is installed under the radome the conduction cooled
variant must be
used. This variant achieves cooling through its base plate and must be installed with the
provided thermal pad to ensure a good thermal path between the KRFU and the AIM or
LAIM. Refer to KRFU Thermal Pad Kit installation Section 4.F., before you install the
KRFU LRU.
(d) When the KRFU is installed inside the aircraft e
ither the cond
uction cooled or forced air
cooled variant may be used.
(e) The KRFU must be installed close to fuselage mount antenna assembly so as to
mi
nimize the waveguide/coax RF losses on the RF interconnect.
