copy is corrupt or is a different version than the one on the SCM. The SCM files always
remain as data loaded. The SDU permits some modifications to its local copy of the User
ORT (for example: addition of telephone numbers), but no modification of the Secure
ORT is permitted. On power up the SDU also checks the validity of each ORT file
including checks on the version compatibility, completeness, compatibility of related
parameters, range checking, and unsupported options. Faults are raised if ORTs are
corrupted. If no valid Secure ORT is present or if the pin strapping is invalid the SDU
enters a "Safe Mode" which prohibits RF transmission until the issue is resolved by data
loading valid Secure ORT, or correcting the strapping.
(4) Based on the configuration the SDU sends the commands necessary to support the
loaded configuration to the other SATCOM LRUs.
(5) For the Aspire 400 SDU, Secure and User ORTs will be created by using the Aspire 400
ORT Tool. This tool will take entered values for ORT parameters, check their validity and
create a loadable software part that can be directly uploaded to the SDU. The tool can be
configured to permit the creation of User and Secure ORTs, or only User ORTs. The tool
flags if any selected features require licensing. The tool is qualified separately as
documented in the Aspire 400 ORT tool qualification plan as per DO-330 [RD14].
(6) ORTs may be created by Honeywell or OEM customers. The tool provides for assignment
of ARINC 665 [ID2] part numbers, which are under the management and control of the
creator. The certification of any customer-developed secure ORT is the responsibility of
the customer.
(7) The data loaded ORT files always reside within SCM. If the SDU is removed for repair the
replacement SDU will align to the files in the SCM without a new data load being
required. Thus, it is not necessary to preserve the work copy of the ORT files within the
SDU when returned from repair.
2. Certification Basis
A. TCCA CAN-TSO Applicability
(1) Honeywell uses the TCCA's Transport Canada Civil Aviation (CAN-TSO) program [RD5],
outlined in Title 14 CFR Part 21, Subpart O [RD6], as a means to obtain certification for
the Aspire 400. The TCCA Technical Standard Order (CAN-TSO) [RD5] and associated
MOPS define the regulatory requirements and performance listed in Table 5-2.
