Definition
A departure from an airport that has been assessed by the FAA as free of obstacles requiring a published Obstacle Departure Procedure (ODP), allowing aircraft to depart in any direction and climb on course without specific obstacle-avoidance instructions, provided the aircraft maintains a climb gradient of at least 200 feet per nautical mile to 400 feet above the departure end of the runway, then continues to climb at 200 feet per nautical mile until reaching the minimum IFR altitude.
Plain English
A diverse departure means the airport has been checked and found clear of obstacles in every direction at the standard climb rate, so an IFR aircraft can depart any runway in any direction without following a special departure procedure, as long as it climbs at the standard rate.
Context Anchor
Seen when planning an IFR departure, especially when checking whether an airport or runway has a published obstacle departure procedure.
Derivation
Diverse comes from the Latin diversus, meaning 'turned in different directions.' In this context it captures the idea that the departure path can go any direction, because all directions have been cleared for obstacle protection.
Why Pilots Care
It provides a safe, flexible way to leave the airport without added restrictions when standard climb performance already clears all obstacles.
Grounding Statement
Picture taking off in low visibility from a runway where the surrounding area has already been checked so a normal climbing turn after takeoff will stay clear of obstacles.
Intuition Check
Diverse does not mean “many different published departures.” Here it means the runway was assessed so departure turns are not restricted to one required obstacle-avoidance path.
Example Sentence 1
Because the airport qualifies for a diverse departure, the pilot planned a direct climb on course after takeoff without consulting an ODP.
Example Sentence 2
The diverse departure let the crew turn on course as soon as they reached the minimum altitude because no obstacles required a specific routing.
