New AC Addresses Runway Overruns

The FAA has issued a new Advisory Circular (91-79) that addresses runway overruns during landing. Overruns occur at the rate of about 10 incidents or accidents per year, and most can be attributed to non-adherence to standard operating procedures, according to FAA and NTSB statistics. AC 91-79 recommends that Part 91, 91 Subpart K, 125 and 135 operators incorporate the risk-mitigation strategies in their operations manuals. The 39-page AC also includes a detailed summary of hazards that cause overruns, a comprehensive section on stabilized approaches and in-depth information about landing-distance calculations.
