Experience the Quality With Free SIFT Exam Questions That Helps Candidates Pass

As forward speed increases, advancing blade airflow increases, retreating blade airflow decreases. To equalize lift, retreating blade AoA increases, eventually exceeding stall angle. This creates vibrations, roll, and loss of control. It limits helicopter VNE (never exceed speed). Options A and C are inaccurate mechanisms; option D confuses advancing vs retreating lift distribution. Correct answer: B.

Simple Drawings items reward precise spatial parsing of short descriptions. The key descriptors are (1) the arrow points upward, (2) the circle is directly to the right of the arrowhead, and (3) both are centered on the same horizontal line. Option B exactly satisfies these: the circle appears to the right of the arrow (not left), the arrow points up (not left), and the relative vertical alignment is level (not above or below). Options A and C violate either direction (arrow points left in C) or left/right placement (A). Option D breaks the “same horizontal line” constraint by placing the circle above the arrow. In SIFT practice, convert verbal statements into a quick mental sketch: fix cardinal terms (left/right/above/below), then confirm orientation words (upward-pointing). Finally, scan answer choices for any single contradiction—one mismatch is sufficient to discard an option rapidly, letting you move efficiently through high-volume, low-time questions.

Verifying multiple features prevents mistakes. Correct: A.

Torque = Force × Distance. Longer lever increases distance, reducing force required. Correct: B.

Ground resonance is self-excited vibration from out-of-phase rotor blades. Correct: A.
