← TechnologyWhich outcome occurs inside an aircraft's electrical circuit when ice accumulation significantly lowers pitot tube pressure readings?
A)Stall warning system activation✓
B)Increased fuel pump efficiency
C)Anti-ice system deactivation
D)Cabin lights begin to flicker
💡 Explanation
Stall warning activates because the *Angle of Attack (AoA) comparator circuit* interprets reduced pressure as critically low airspeed. Therefore, the AoA increases to stall value, rather than adjusting speed; incorrect pressure skews sensor interpretation under normal loads.
