Definition
End of Descent (E/D) is a defined point in a vertical navigation (VNAV) flight profile that marks where the descent phase ends and level flight resumes. It is typically the point at which the aircraft levels off at a new assigned altitude after descending from a higher cruise or intermediate altitude.
Plain English
E/D is the spot in a planned descent where the aircraft stops going down and levels off at the new altitude.
Context Anchor
Seen in instrument procedure and flight-management displays that describe the vertical path of a route or procedure.
Why Pilots Care
Knowing the E/D helps pilots anticipate when to level off, manage power and pitch for the transition, and cross-check the FMS-calculated descent path against ATC clearances and altitude restrictions.
Intuition Check
Do not read “Decent” as meaning “acceptable” or “good enough.” In this aviation context, E/D refers to the end of a descent: the airplane’s planned movement to a lower altitude.
Example Sentence 1
The FMS showed the E/D about three miles before the next waypoint, so the pilot reduced the descent rate and prepared to level off at 8,000 feet.
Example Sentence 2
Reaching the E/D early required a slight level-off before continuing the descent.
