CS 26.205 Runway overrun awareness and alerting systems ED Decision 2020/023/R Compliance with point [26.205](#_DxCrossRefBm881534068) of Part-26 is demonstrated by showing compliance with CS 25.705, or with the following: (a) During approach (from a given height above the selected runway) and landing, the runway overrun awareness and alerting system (ROAAS) shall perform real-time energy-based calculations of the predicted landing stopping point, compare that point with the location of the end of the runway, and provide the flight crew with: (1) in-flight, timely, and unambiguous predictive alert(s) of a runway overrun risk; and (2) on-ground, timely, and unambiguous predictive alert(s) of a runway overrun risk. At the option of the applicant, the ROAAS may also provide an automated means of deceleration control that prevents or minimises runway overruns during landing. (b) The ROAAS must at least accommodate dry and wet runway conditions for normal landing configurations. [Issue: 26/3]
