Definition: Distance per unit altitude loss; maximized at best (L/D)_max speed.
Physics insight: The L/D curve is shaped by parasite and induced drag components.
Example: In emergencies, fly best glide speed to maximize range.
(L/D)_max → minimum C_D/C_L
Rules of thumb: Account for wind and terrain; consider flap/gear configuration.
Common pitfalls: Failing to adjust for weight changes.
