R R R R R R R R C. Activation of the Functional Test The functional test can be activated by pushing the line key adjacent to the TEST indication on the ILS maintenance sub-menu, under the following conditions: test inhibit discrete not active and A/C on ground. It is similar to the receiver face test except that the receiver face LEDs are not controlled to reflect the status of the unit, which is reported on the MCDU.
R R R R NOTE : If the test cannot be initiated on ground on the MCDU (which means____ that a fault affects either the LGCIU, the FMGC or the ILS), a TEST page comes into view on the MCDU. (Ref. Fig. 012A, 013A)

D. Power-up Tests Initialization and Cockpit Repercussions
(1) Conditions of power-up tests initialization - How long the computer must be de-energized: 1 s. - A/C configuration: - whatever the A/C configuration on ground
(2) Progress of power-up tests - Duration: 1 s. - Cockpit repercussions directly linked to power-up test accomplishment (some other repercussions may occur depending on the A/C configuration but these can be disregarded): - MASTER CAUT light on

(3) Results of power-up tests (cockpit repercussions, if any, in case of tests pass/tests failed). - Tests pass: - MASTER CAUT light off - ILS information available on ND and PFD if ILS selected on the FCU - Tests failed: - MASTER CAUT light on - ECAM warning NAV ILS 1 or 2 FAULT - ECAM STATUS ILS 1 or 2 INOP * if ILS selected on FCU - CAPT (F/O) PFD ILS 1 (2) and LOC and GLIDE scales in red - CAPT (F/O) ND ILS 1 (2) in red

(1) BITE description The BITE facilitates maintenance on in-service aircraft. It detects and identifies a failure related to the ILS. The BITE of the ILS receiver is connected to the CFDIU (Ref. 31-32-00). The BITE: - transmits permanently ILS status and its identification message to the CFDIU - memorizes the failures which occurred during the last 63 flight legs - monitors data inputs from the various peripherals - transmits to the CFDIU the result of the tests performed and selt-tests - can communicate with the CFDIU through the menus. The BITE can operate in two modes:
- the normal mode - the menu mode.
(a) Normal mode During the normal mode the BITE monitors cyclically the status of the ILS. It transmits its information to the CFDIU during the concerned flight. In case of fault detection the BITE stores the information in the fault memories. These items of information are transmitted to the CFDIU by an ARINC 429 message with label 356.
(b) Menu mode The menu mode can only be activated on the ground. This mode enables communication between the CFDIU and the ILS BITE by means of the MCDU.
