Figure 4-12. LAIM Assembly with FMA and KRFU Placement on Aircraft
On completion of the LRU interconnection and applying power to the FMA, the FMA will stay in its
current
position until it is told to move by the KANDU.
(6) KRFU Installation Location with the
TMA (if applicable)
The KRFU install location at the top of aircraft tail empennage is airframe specific.
The KRFU can be installed either forward or aft of the tail mount antenna assembly. The
KRFU can also be installed in any orientation as long as space permits, interconnection
routing is feasible, and adequate thermal conduction path is maintained. Antenna blockage
analysis/review should be carried out to ensure that acceptable system performance is
maintained.
The conduction cooled KRFU variant requires mounting of the Honeywell recommended
thermal pad to aircraft structure capable of handling KRFU thermal loads. Refer to
Paragraphs 4.6.A, 4.6.B and 4.6.C.
The forced air cooled KRFU variant may be used as an alternate installation option. A duct
and in line fan may be used to drawn hot air from the KRFU integrated heat sink and duct it
down to lower sections of the tail/empennage structure.
The KRFU must be installed close to the TMA assembly so as to minimize the
waveguide/coax RF losses on the RF interconnect.
