Setup of the system 5
This chapter has the following sections:
• Software upload
• SATCOM system ready for use
5.1 Software upload
5.1.1 Overview
After the physical installation of the system it must be loaded with the following files:
• Software image for the system, i.e. CSDU and antenna (typically factory loaded)
• Secure ORT (Owner Requirements Table)
•User ORT
Software image files should only be loaded via Ethernet (ARINC 615A) data loader as an
ARINC 429 data loader (A615-3) would require more than 2 hours. All ORT files are loaded
using an ARINC 429 or Ethernet (A615A) data loader.
The software image makes the system ready for configuration to the specific aircraft
installation and application requirements. The ORT files contain the settings for the
individual aircraft. The Secure ORT contains all aircraft specific settings. The User ORT
contains user data, e.g. a telephone directory.
Line of sight
You can configure the system while the aircraft is in the hangar. Note that you
cannot typically check the satellite communication while the aircraft is still in the
hangar. There must be a line of sight between the SATCOM antenna and the
satellite in order to register and use the satellite service.
