Which braking action code indicates "Poor" (≤0.25)?

The braking action code that indicates "Poor" (≤0.25) is represented by Code 1. In the context of aviation, braking action codes are crucial for pilots and air traffic control as they provide standardized information regarding the stopping capability of an aircraft on a runway.

A Code 1 designation denotes that the braking action is poor, which signifies that the runway conditions have a considerable adverse impact on the braking performance of an aircraft. Understanding this code is fundamental for pilots when making landing decisions, as a poor braking action could lead to longer stopping distances and increased risk during landing operations.

In aviation standards, there are specific thresholds established for various braking action codes that range from "Good" to "Nil," with Code 1 being the lowest in terms of braking efficiency. This systematic categorization is designed to enhance safety by ensuring that pilots are aware of potential hazards related to runway conditions.
