When neither caution nor warnings are present the page shown is controlled by flight phase.
• On the ground and engines off -> Doors page
• On the ground and engines on -> Wheels page
• Take-off run and until reaching 1500 ft AGL -> Engines page
• Above 1500 AGL -> Cruise page
If a caution or warning is triggered the ECAM will show the page for the affected system and CLR button
will be lit. Pressing CLR will show to next affected systems page (if any) otherwise it will return to the page
relevant for the flight phase. Pressing RCL will recall any existing warnings and cautions and again show
the page for the affected systems.

STANDBY COMPASS
The standby compass is displayed when the access panel is pushed upwards shortly. It can be stored by
pushing it upwards. The standby compass should not be used for normal operation.
STANDBY HORIZON
The standby horizon is a backup for the IRU and EFIS system and shows attitude, altitude, speed and
barometric pressure. The standby horizon should not be used for normal operation.
DDRMI
The digital distance and radio magnetic indicator provides a backup for the flight displays but is also useful
in normal operation.
