wouldn't you recover the energy back while landing in same sense with car breaks that recharges the battery

• Ekaros 3y ago
  There is constant energy expenditure to stay in air. Unlike with ground or sea vehicles that don't need it.
  • bbojan 3y ago
    Yes, the technical term for that is "lift induced drag".
    • barelyauser 3y ago
      No, it's just drag. Extended landing gear is also a constantly expenditure but generates no lift.

        > Extended landing gear is also a constantly expenditure but generates no lift Negligible lift. Fluid flowing around an object generates lift. Drag is more intuitive; if there is drag, there is lift. (They're just components of the aerodynamic force relative to the direction of relative fluid flow.)
