 Level 2 Level 2, current faults, provides a listing of the internal and external faults currently detected by the Enhanced GPWC. Level 2 self-test is initiated by pressing the GPWS/G/S pushbutton switch within 3 seconds after the end of level 1 self-test.

 (c)
 Level 3 Level 3, Enhanced GPWS configuration, indicates the current configuration by listing the current hardware, software, data bases and program pin inputs detected by the Enhanced GPWC. This level is initiated by pressing the GPWS/G/S pushbutton switch when PRESS TO CONTINUE message is enunciated.

 (d)
 Level 4 Level 4, fault history, provides a historical record of both internal and external faults detected by the Enhanced GPWC. This level is initiated by pressing the GPWS/G/S pushbutton switch when PRESS TO CONTINUE message is enunciated.

 (e)
 Level 5 Level 5, warning history, provides a historical record of the warnings and cautions given by the Enhanced GPWC. This level is initiated by pressing the GPWS/G/S pushbutton switch when PRESS TO CONTINUE message is enunciated.

 (f)
 Level 6 Level 6, discrete test, provides annunciation of discrete input transitions to be used for maintenance support. This level is initiated by pressing the GPWS/G/S pushbutton switch when PRESS TO CONTINUE message is enunciated.

 (3) To speed up the navigation of self-test levels and information two types of cancel sequences are supported. Pressing and holding the GPWS/G/S pushbutton switch for less than 2 seconds is considered to be a short cancel. Pressing and holding the cockpit GPWS/G/S pushbutton switch for more than 2 seconds is considered to be a long cancel.

 Interactive function To gain access to the BITE, it is necessary to use one MCDU (Ref. 22-82-00). All information displayed on the MCDU during the BITE TEST configuration can be printed by the printer (Ref. 31-35-00).

 (2)
 BITE description The BITE facilitates maintenance on in-service aircraft. It detects and identifies faults related to the Enhanced GPWS. The BITE of the Enhanced GPWC is connected to the CFDIU. The BITE:

 -continuously transmits Enhanced GPWS status and its identification message to the CFDIU,
 -memorizes the faults which occurred during the last 63 flight segments,
 -monitors data inputs from the various peripherals (FMGC, RA transceiver, ILS receiver, ADIRU, SFCC, LGCIU, ECAM control panel and CFDIU),
 -transmits to the CFDIU the result of the tests performed,
 -can communicate with the CFDIU through the menus. The BITE can operate in two modes:
 -Nnormal mode

 - Interactive mode.
 (a) Normal mode During normal mode, the BITE monitors cyclically the status of the Enhanced GPWS. It transmits its information to the CFDIU during the given flight. 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.
 (b) Interactive mode The interactive mode can only be activated on the ground. This mode enables communication between the CFDIU and the Enhanced GPWC BITE by means of the MCDU. The Enhanced GPWS menu mode is composed of: - LAST LEG REPORT
