The menu mode The menu mode can only be activated on the ground. This mode enables communication between the CFDIU and the HF transceiver BITE. This is by means of the MCDU. The HF transceiver menu mode is composed of:

A. Built-In Test Equipment (BITE) The BITE facilitates maintenance on in-service aircraft. The BITE detects and determines a failure related to the HF system. The BITE of the HF transceiver is connected to the Centralized Fault Display Interface Unit (CFDIU) (Ref. ATA 31-32). The BITE:
-transmits permanently HF system status and its identification message to the CFDIU
-memorizes the failures occurred during the last 63 flight segments
-monitors data input from the various peripherals (RMP and CFDIU)
-transmits to the CFDIU the result of the tests performed and self-tests
-can communicate with the CFDIU by the menus.

B. General Operation
The BITE may operate in two modes:
-
the normal mode
-
the menu mode.
(1)
The normal mode During the normal mode the BITE monitors cyclically the status of the HF system. It transmits its information to the CFDIU during the flight concerned. In case of fault detection the BITE stores the information in the fault memories. These items of information are transmitted to the CFDIU every 100 ms by an ARINC 429 message with label 356.
(2)
The menu mode The menu mode can only be activated on the ground. This mode enables communication between the CFDIU and the HF transceiver BITE. This is by means of the MCDU.
