-
the SYSTEM 1 and SYSTEM 2 Full Authority Digital Engine Control Systems (FADEC)

 -
the Slat and Flap Instrumentation Position Pick-Off Units (IPPU)

 -
the SYSTEM 1 and SYSTEM 2 Radio Altimeters.

 When the aircraft is in one of the configurations that follow, the FWCs and the ECAM system will:
 -put the red master warning lights on
 -show the warning message L/G NOT DOWN on the upper ECAM DU
 -sound a continuous repetitive chime
 -put the red down arrow on (L/G control-lever). The red down arrow does not come on when the aircraft is in flight phase 4, 5 and 6 (when a minimum of one radio altimeter is serviceable).
 The warning L/G NOT DOWN occurs when the L/G is not locked down and a mimimum of one LGCIU is serviceable and:
 (a) The aircraft is below 750 ft radio height with the engines not at takeoff power and it has one of these conditions:
 -two engines below 75% RPM
 - one engine below 97% RPM with the other ENG/MASTER control switch in the OFF position
 -and the conditions of paragraphs (b) and (c) are not applicable.

(b)
 The aircraft is below 750 ft radio height with:

 -a flap position of 18 degrees or larger and a slat position of 16 degrees or larger
 -engines not at takeoff power.

 (c)
 The aircraft is in flight phase 6 with two unserviceable radio altimeters:

 -and has a flap position of 24 degrees or larger and a slat position of 24 degrees or larger.
