2 Boeing Safety Runway overrun excursions Runway excursions are the first leading cause of aviation accidents and the third leading cause of transport airplane fatalities - A top issue U.S. NTSB - Runway safety - top 10 since 1991 Flight Safety Foundation IATA ICAO GRSS in May A top issue - Recognized accident issue - A top issue Copyright 2014 Boeing.

3 Boeing Overrun characteristics Stability Touch-down Deceleration Unstable approach (too high, too fast) Tailwind AB too low Friction limited or runway contamination Long landing Speedbrakes late or not deployed Reversers late or not deployed Runway excursions often are caused by more than one factor High touchdown speed Reverser level too low or reduced too soon Decision height Copyright 2014 Boeing.

4 Embraer Overrun Characteristics Stability Touch-down Configuration Unstable approach Crosswind Others Long landing Vref excedance Friction limited or runway contamination Overrun excursions often are caused by more than one factor! Insufficient braking Decision height Touchdown Copyright 2014 Boeing. All rights reserved. RSAG PA-RSAT 4

7 Boeing and Embraer: Overrun Mitigation Runway Situation Awareness Tools (RSAT) Technology Procedures Flight Deck Technology Approach planning tools Runway positional awareness and Runway alerting Stability guidance and alerting Predicted runway stop location Overrun alerting For every landing: Landing distance calculation Go-around point Utilize appropriate callouts Training Video Training Aid video Stable approach Runway friction Runway available vs. required Reported conditions vary Approach speed additives Proper, timely use of deceleration devices Copyright 2014 Boeing. All rights reserved. RSAG-RSAT 7

8 Procedures Perform a landing distance calculation and assessment Plan a go-around point or a latest touchdown point Ensure required procedural callouts are made Note: A thrust reverser callout and a landing distance calculation were added to the FCTM and the FCOM Procedures Flight Deck Technology Training Video Copyright 2014 Boeing.
