Check illumination of the green
light located above the switch
(except if hot conditions)

Increase power so as to get Ng ≥ 80% to check AIRFRAME DE ICE
Theoretically, necessary air bleed to inflate wing and empennage
leading edges, as well as depression necessary to their deflation
are sufficient when power lever is positioned on IDLE. However, it is
advised for check to choose a Ng power ≥ 80 % in order to obtain
operation design pressure, which enables illuminating surely the
two green lights and avoiding ”VACUUM LO” untimely alarms.
–”AIRFRAME DE ICE” switch ON. . . . . . . . . . . . . . . . . . . . . . . . . .
Visually check functioning of deicer boot
during 1 total cycle and illumination of the
two green lights located above the switch
The cycle lasts 67 seconds. Check both inflation impulses, and
illumination of each corresponding green light :
– the first impulse inflates the external and middle wing boots,
– the second impulse inflates the leading edge boots of
empennages and inner wing.
