-Manual mode (or flight crew mode) In this mode, the crew selects manually the desired system page by means of the ECAM control panel related key, which comes on. This mode enables the crew to select any system page except the cruise page. In case of total loss of the ECAM CP, the ALL key enables the crew to have successively on display all the system pages and to stop on the desired system page. The pilot can obtain this sequencing of the system pages by successive pushes on the ALL key, or if he presses it continuously. In the latter case, all the system pages appear successively at approximately 1 s time intervals, up to the last one (CRUISE). The pilot must release the key to re-initialize the stack pointing device and to have the first system page (ENG). This ALL key feature is particularly useful in case of ECAM DU failure, and generally speaking whenever there is only one DU left for ECAM display (Mono mode).
-Flight phase related mode (Ref. Fig. 033) This mode engages only when the other modes are not engaged. In this mode, a given page is automatically shown, according to the current flight phase.
NOTE : The A/C system page corresponding key on the ECAM control
____ panel comes on only in the Advisory mode and in the manual mode. To press the key in this case removes the current A/C system page from the lower ECAM DU, and the flight phase related A/C system page replaces it.
NOTE : The flight crew can at any time select an A/C system page
____ if he presses the corresponding key, which then comes on. If the flight crew presses the on key, the A/C system page currently on display is replaced:
-either by the one corresponding to the present warning, possibly and if the warning presentation sequence had not been cleared
- or by the flight-phase related A/C system image.

-Priority between the different modes Mode 1 : Automatic mode related to a failure. This mode has priority over all the others but can be superseded if a system page is called manually. It is disengaged if the warning message is cleared by means of the CLR key or if the failure conditions have disappeared. Mode 2 : Automatic advisory mode This mode has priority over modes 3 and 4. It is disengaged if the corresponding system key is pressed or if another system is called manually. A system page displayed in advisory mode and disengaged cannot be called again in advisory mode for the same parameter. However, if the parameter is still in the advisory range, it continues pulsing on the relevant page when this page is for instance called manually. Disengagement is automatic when a warning occurs or when the parameter is back to normal. Mode 3 : Manual mode This mode can be engaged at any time but is disengaged if mode 1 or 2 is engaged. Mode 4 : Automatic mode related to the flight phase This mode is automatically engaged if the other modes are not engaged.
