6 Runway Situation Awareness Tools (RSAT) Known 737 Runway End Excursions During Landing*: *Includes veer-offs to avoid runway end excursion BOEING PROPRIETARY SAAFER 6

7 Runway Situation Awareness Tools (RSAT) Procedures Flight Deck Technology Technology Enhanced approach planning tools Predicted runway stop location display Visual and aural runway positional awareness and alerting Stability guidance and alerting Overrun alerting For every landing Perform a landing distance calculation Calculate and brief a go-around point Use appropriate Speedbrake/Thrust Reverser callouts Training Video Approach and Landing Training video No Landing is Routine Flying a stable approach Runway contamination or friction Checking runway length available versus required Reported unanticipated conditions Approach speed additives and effect Proper, timely use of all deceleration devices SAAFER 7

14 737 Autopilot Changes Loss of Control Mitigation Autopilot formerly reverted to Control Wheel Steering (CWS) mode when: Pilot would override the autopilot using column or wheel Pilot would engage the autopilot while banking Several instances where the CWS mode was misunderstood In these situations the autopilot will now disengage and provide a warning SAAFER 14

15 Roll Command Alerting System For 737 Initially Helps pilots recover from high bank angle events Highlights asymmetry issues that cause yaw-induced roll Alerts pilots when autopilot saturation occurs Provides directional guidance when excessive bank angles are reached Functions identically in all flight control modes SAAFER 15

16 737 Roll Command Alerting System ROLL/YAW ASYMMETRY Caution ROLL / YAW ASYMMETRY displayed at 75% autopilot authority No aural Message also appears on HUD (if installed) SAAFER 16

17 737 Roll Command Alerting System ROLL AUTHORITY Caution ROLL AUTHORITY displayed at 100% autopilot authority ROLL AUTHORITY aural Message also appears on HUD (if installed) SAAFER 17

18 Roll Command Alerting System ROLL LEFT / ROLL RIGHT Warning At 35 o bank At 45 o bank BANK ANGLE aural at 35 o of bank ROLL RIGHT or ROLL LEFT aural at 45 o of bank Red directional arrow at 45 o of bank Roll arrow also appears on HUD (if installed) SAAFER 18
