SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
E. OAE Installation
Installation hardware is available in ARINC 791 Style configurations and non ARINC 791 style
configurations. Equivalent acceptable hardware may be designed by the customer or procured
from other sources.
For the ARINC 791 configuration; the seven aircraft side fittings, internal structural modifications,
internal wiring, radome and bulkhead connectors are the responsibility of the installer.
For the non ARINC 791 configuration; the LAIM to fuselage interface brackets, skirt fairing attach
points, internal structural modifications, internal wiring, radome and external OAE power and control
and IF coax interconnects and routing hardware, are the responsibility of the installer.
F. Airframe Structural Modifications
For the installation of OAE-FMA, structural modifications to the airframe may be required in the
region where the OAE-FMA is to be mounted to accommodate the additional mass of the antenna
assembly and resulting aerodynamic loads.
The aerodynamic loads are dependent on the aircraft type as well as the installation location of
the OAE-FMA on the aircraft, and are therefore installation specific.
Bird strike and rapid decompression need to be considered for analysis and structural substantiation.
The appropriately qualified personnel should derive the loads and do a structural analysis to make
sure of the suitability of the modifications.
The installer is responsible for all structural modifications to the aircraft.
G. Mounting Guidelines
This section describes the mounting guidelines for fuselage mount OAE.
Physical Placement:
The aircraft fuselage mount OAE is installed on top of the fuselage for clear satellite communications
per ARINC791 P1.
The FMA maybe installed anywhere on top of the aircraft, with due consideration for aerodynamic
loading and potential for interference with adjacent systems.
The FMA may be installed anywhere on the top of the aircraft, Honeywell recommends not installing
the FMA at the mid fuselage station near the wing or slightly aft of the wing due to higher aero
loads.
The fuselage antenna assembly and BUC-HPA (if installed outside the aircraft) will be mounted
on the antenna interface mount and it supplies a means to secure all equipment and wiring mounted
on it.
Depending on the airframe, the AIM/LAIM is installed to provide a firm flat base for installation of
the FMA and BUC-HPA. These are detailed in the next sections. For customers who want to build
their own AIM, please reference the third-party OAE specification, SP-90405087.
H. FMA Bonding
The bonding straps are installed before proceeding with installation of FMA assembly on the A791
based AIM or LAIM.
The FMA assembly and BUC-HPA must be bonded to the airframe.
