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 throttle is positioned on Flight 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 LOW”
untimely alarms.
