It applies both to the

individual airfoils comprising the wing and to the wing itself

It applies to the full

wing but not to the individual airfoils comprising it

It

applies locally to the individual airfoils comprising the wing but not to the

wing itself

It applies neither to

the full wing nor to the individual airfoils comprising it

D'Alembert's paradox is

utterly irrelevant to lifting-line theory

the friction drag is

larger compared to the case of turbulent BL

if any, the flow

detachment point is usually closer to the TE compared to the case of turbulent

BL

the BL

is always laminar at the beginning

if existing, the wake or

pressure drag is smaller compared to the case of turbulent BL
