Definition
A Light Sport Aircraft (LSA) whose airframe configuration produces a high level of aerodynamic drag relative to typical training airplanes — for example, fixed landing gear with large tires, external bracing struts, exposed control linkages, or a high-lift wing. The increased drag causes the airplane to decelerate quickly when power is reduced and to require relatively more power in cruise to maintain airspeed.
Plain English
A small sport airplane built in a way that creates a lot of air resistance, so it slows down fast when you pull the power back.
Context Anchor
Encountered in light-sport aircraft training, especially when learning approaches, landings, power changes, and power-off glide behavior.
Derivation
‘Drag’ comes from Old Norse ‘draga,’ meaning to pull or hold back — describing the rearward force the air exerts on the airplane. ‘LSA’ is Light Sport Aircraft, an FAA category for small, simple airplanes flown under sport pilot rules.
Why Pilots Care
Understanding high-drag LSAs helps pilots adjust approach speeds, landing distances, and energy management to avoid runway overshoots or unstable approaches.
Grounding Statement
When power is reduced, a high-drag LSA can feel as if the air is holding it back, so speed and height can disappear quickly.
Intuition Check
High-drag does not mean the aircraft is poor or unsafe. It means the aircraft has more air resistance, so it slows and descends more quickly when power is reduced.
Example Sentence 1
Because the trainer was a high-drag LSA, the instructor reminded the student to carry a little extra power on final to avoid sinking below the glidepath.
Example Sentence 2
After flying the high-drag LSA, the pilot noticed the longer landing rollout compared with sleeker trainers.
