drag during climb refers to the aerodynamic force that opposes the aircraft’s motion as it ascends at a specific rate of climb while flying at a particular airspeed and altitude. Understanding drag during climb is crucial for assessing an aircraft’s performance during climbing maneuvers and for optimizing its efficiency
Dc=0.5*ρ*v2*s*Cdc
Dc means drag during climb
ρ means density
v means velocity
s means wing area
cdc means drag coefficient in climb
