Definition
A faulty landing in which the airplane is allowed to settle onto the runway from an excessive height during the round out, resulting in a hard, uncontrolled touchdown rather than a smooth transition from flight to ground roll. It typically occurs when the pilot levels off too high and fails to continue the gradual back-pressure needed to keep the airplane flying just above the surface until it settles on its own.
Plain English
A landing where the airplane stops flying while still well above the runway and falls the last few feet onto its wheels instead of easing down gently.
Context Anchor
Encountered in landing training when discussing the round out, flare, and common touchdown errors.
Derivation
From the everyday phrase 'drop in,' meaning to fall or arrive abruptly. The name describes exactly what happens: the airplane drops onto the runway rather than touching down smoothly.
Why Pilots Care
This error produces hard landings that can damage landing gear, propellers, or cause loss of directional control, especially in tailwheel aircraft.
Grounding Statement
Picture the airplane a few feet above the runway with too little speed left; instead of continuing to float down gently, it sinks quickly onto the wheels.
Intuition Check
“Drop-in” does not mean a normal landing that simply arrives at the runway. Here it means an unwanted, abrupt drop during the last moments before touchdown.
Example Sentence 1
The student leveled off about ten feet above the runway, lost flying speed, and made a drop-in type landing that jolted the airplane onto its main gear.
Example Sentence 2
In crosswind conditions a drop-in type landing can lead to a sudden sideways drift and loss of directional control on touchdown.
