What happens to the pitch of an aircraft when the elevator is pulled back?

When the elevator is pulled back, it causes the horizontal stabilizer to push down on the tail of the aircraft, which results in the nose of the aircraft moving up. This change in pitch is fundamental to controlling an aircraft's flight path. Pulling the elevator back effectively increases the angle of attack of the wings, leading to a climb if sufficient speed and lift are maintained.

Understanding how the elevator affects pitch is crucial for pilots, as it helps them manage the aircraft's ascent and descent during takeoff, level flight, and landing phases. The other options touch upon different aircraft behaviors that do not directly correlate with the specific effect of pulling back on the elevator. In contrast, option B directly reflects the fundamental aerodynamic principles at play when manipulating the elevator control surface.
