Plain English Meaning

Short obstacles like trees, poles, or small buildings sitting close to the end of the runway. Instead of forcing every aircraft to climb more steeply to clear them, the procedure just lists them so the pilot knows they are there and can avoid them visually.

Full Definition

Obstacles located near the departure end of a runway that are lower than 200 feet above the runway elevation and within one nautical mile of the runway. When such obstacles would otherwise require a steeper-than-standard climb gradient for the entire departure, they may instead be noted in the textual description of the instrument departure procedure rather than raising the published climb gradient. Pilots are expected to see and avoid these obstacles using normal climb .
