The flare technique question posed in this discussion — whether to apply back pressure at a constant rate or use a reactive, incremental approach during landing — cuts to the heart of one of the most perishable stick-and-rudder skills in aviation. The correct answer, supported by aerodynamic principles and professional training doctrine alike, favors smooth, continuous back pressure applied at a progressively increasing rate as the aircraft decelerates in ground effect, rather than a stop-and-go reactive technique. The reactive method — add pressure, pause, wait for the nose to drop, then correct — introduces a feedback loop that is fundamentally out of phase with the aircraft's pitch dynamics, which is the textbook precondition for pilot-induced oscillation (PIO). PIO during the flare is not merely uncomfortable; it is a documented cause of hard landings, runway excursions, and in transport category aircraft, structural overload events.
The aerodynamics of ground effect explain why constant, managed back pressure is superior. As an aircraft descends into ground effect — typically within one wingspan of the runway surface — induced drag decreases and lift increases, causing the aircraft to "float" if energy is not properly managed. During this phase, the pilot's task is to simultaneously arrest the descent rate and bleed airspeed so that the wheels touch down at or near minimum flying speed. Continuous back pressure accomplishes both: it raises the pitch attitude to reduce the angle of attack's contribution to sink rate while simultaneously increasing drag and reducing lift incrementally. A reactive pilot who pauses and waits for the nose to drop before adding more pressure is essentially allowing the aircraft to re-enter a descent before correcting — each correction then tends to over-arrest the sink, setting up the oscillation. The phase lag between pilot input and aircraft response, particularly in larger or heavier aircraft with greater inertia, makes the reactive technique increasingly dangerous as aircraft weight and size increase.
Professional flight training manuals for both transport category and business aviation consistently describe the flare as a single, deliberate pitch attitude change initiated at a prescribed height above the runway — typically 20 to 30 feet in light jets and 40 to 50 feet in large transport aircraft — followed by a hold or gentle continuation of that attitude until touchdown. Boeing's FCTM and Airbus FCOM documentation both frame the flare as targeting a specific pitch attitude rather than managing a dynamic sink rate correction in real time, precisely because attitude-based flying removes the reactive feedback loop from the equation. Crew resource management protocols in multi-crew operations reinforce this by having the pilot monitoring call out sink rate deviations, allowing the flying pilot to make one smooth correction rather than a series of reactive inputs. In high-performance business jets such as the Gulfstream G650 or Bombardier Global 7500 — aircraft with high wing loading and significant inertia — the consequences of reactive, oscillatory back pressure inputs are amplified, and type-specific training emphasizes establishing the flare attitude and holding it with minor refinements only.
The broader implication for operators and instructors is that landing technique degradation is a well-documented currency problem, particularly for Part 91 and 135 pilots who may operate intermittently or transition between aircraft types frequently. The reactive, "chase the nose" flare is a symptom of either insufficient currency or an incomplete mental model of what the flare is actually accomplishing aerodynamically. Recurrent training programs that use FOQUS data or QAR analysis frequently identify flare-related hard landing events that trace back to this exact input pattern — abrupt pitch corrections following a pause in back pressure. Simulator-based instruction that specifically targets flare technique, including scenarios with slightly long or short energy states, is the most effective tool for building the consistent, progressive back pressure habit that separates professional landings from survivable ones.
