• N1 stagger with thrust levers aligned
• decrease or increase in Reference/Target N1 at constant
altitude and speed
• unable to achieve maximum continuous or maximum
climb rating with thrust levers fully advanced
• TAT remains constant and near 0 degrees C during climb,
cruise, or descent.

icing:
• autothrottle disconnects and Reference/Target TPR and
Reference TPR are blanked
• thrust lever stagger with EPR aligned
• EPR stagger with thrust levers aligned
