Definition
Flight conducted at airspeeds near the lower end of the aircraft's flight envelope, where the wing is operating at a high angle of attack to produce enough lift, and where small changes in pitch, power, or configuration produce disproportionately large effects on aircraft behavior. In this regime the airplane is approaching, but not yet at, an aerodynamic stall.
Plain English
Flying the airplane intentionally slow — close to the speed at which the wing would stop producing enough lift — so the pilot learns how the aircraft handles when it is on the edge of stalling.
Context Anchor
Seen in instrument training when practicing precise airplane control at reduced airspeeds, especially while holding altitude and heading by reference to the instruments.
Why Pilots Care
Recognizing and managing slow-speed flight prevents unintended stalls during critical phases such as landing and missed approaches.
Grounding Statement
At slow speed, the airplane is still flying, but it responds more softly and needs more careful control than it does at normal cruise speed.
Intuition Check
Slow-speed flight does not mean flying as slow as possible. It means flying slowly enough to practice control near the stall range, while still keeping the airplane safely under control.
Example Sentence 1
During training, the instructor had the student practice slow-speed flight to feel how the controls respond just above the stall.
Example Sentence 2
In slow-speed flight the controls felt less responsive, so the pilot used larger inputs to keep the wings level.
