Airspeed at which an aircraft experiences the lowest amount of aerodynamic drag. This is a crucial concept in aviation because it represents the point at which an aircraft can achieve the most efficient use of its engine power for a given lift-to-drag ratio.\
- Vmd: Velocity at minimum drag (speed at which the aircraft experiences minimum drag).
- w: Weight of the aircraft.
- ρ: Density of the air through which the aircraft is flying.
- S: Wing reference area of the aircraft.
- CLmd: Lift coefficient at minimum drag condition.
