Definition
Rearward control inputs applied to the control yoke or stick that deflect the elevator upward, raising the aircraft's nose or preventing it from dropping. In straight-and-level flight, increasing back-elevator pressure raises the angle of attack to maintain altitude, particularly as airspeed decreases.
Plain English
Pulling back on the yoke, or holding a slight pull, to keep the nose where you want it. The slower the airplane gets, the more pull is needed to keep it from sinking.
Context Anchor
Seen in instrument flying when adjusting airspeed while trying to keep the airplane straight, level, and on altitude.
Derivation
"Back" refers to the direction the pilot moves the controls (toward themselves), and "elevator" is the hinged surface on the tail that controls pitch. "Pressures" (plural) is used deliberately because pilots apply varying amounts of force, not fixed positions — it is a continuous, adjustable input rather than an on/off action.
Why Pilots Care
As airspeed decreases, the wings produce less lift at a given angle of attack, so the pilot must progressively increase back-elevator pressure to hold altitude. Failing to do so causes the nose to drop and the aircraft to descend.
Grounding Statement
As the airplane slows or power changes, it may need a gentle pull on the controls to keep the nose from settling lower than intended.
Intuition Check
Do not read “pressure” here as air pressure or hydraulic pressure. It means the pilot’s physical force on the flight controls, applied backward toward the pilot.
Example Sentence 1
As the airplane slowed during the airspeed reduction, the pilot smoothly increased back-elevator pressure to maintain altitude.
Example Sentence 2
Too much back-elevator pressure at low speed can cause the nose to pitch up sharply.
