(b) 152 ft/min
(c) 200 ft/min
(d) 200 ft/nm

Answer 1

An obstacle departure procedure (ODP) is established if a steeper than normal climb gradient is required by identification of a slope of 152 ft/nm (feet per nautical mile).

Step-by-step explanation:

An obstacle departure procedure (ODP) is established if a steeper than normal climb gradient is required by identification of a slope of 152 ft/nm (feet per nautical mile). The ODP helps ensure that an aircraft can safely climb over obstacles after takeoff.

The climb gradient represents the rate at which an aircraft ascends vertically relative to the horizontal distance it covers. It is usually expressed in feet per nautical mile (ft/nm). A higher climb gradient indicates a steeper climb, which allows the aircraft to clear obstacles more effectively.

For example, an ODP with a slope of 152 ft/nm would require the aircraft to climb 152 feet vertically for every nautical mile it travels horizontally. This steeper climb gradient helps ensure that the aircraft can safely clear obstacles, such as buildings, hills, or trees, in the vicinity of the airport.
