Sec.3.4 - Where should a pilot start descent?

Applied Project in Sec.3.4, Calculus by Stewart Chinese version: 飛行員應該何時開始下降高度? An approach path for an aircraft landing is shown in the figure and satisfies the following conditions: (i) The cruising altitude is $h$ when descent starts at a horizontal distance $\ell$ from touchdown at the origin. (ii) The pilot must maintain a constant horizontal speed $v$ throughout
