3 SWA Flight 1248, Chicago Midway, Dec 8, 2005

4 Boeing 737 ran off departure end of Rwy 31C 1 Death 1 Serious Injuries 21 Minor Injuries Aircraft Substantially Damaged

5 7:14 PM (Night) Temperature - 28 F ½ Mile Visibility Moderate Snow Freezing Fog All aircraft systems functioning normally No crew impairment

6 Only Rwy 31C offered an approach above minimums 8 knot tailwind Rwy 31C plowed 27 minutes prior to landing Braking Action reported as fair to poor * Rwy 31C 6522x150

7 NTSB s Safety Issues: Flight Crew ADM SWA policies, guidance, and training Arrival landing distance assessments Safety Margins Runway Safety Areas Runway surface condition assessments Braking action reports Airplane-based friction measurements

8 NTSB s Recommendations: Develop and issue formal guidance regarding standards and guidelines for the development, delivery, and interpretation of runway surface condition reports.

9 The FAA Forms the TALPA ARC FAA How do we improve the methods of assessing and reporting runway conditions? OEMs Regulators Air Carriers Airport Operators

10 Recommendation, Effective October 1, 2016: All parties use standardized terminology...

11 TALPA What s Common? Type Depth Temperature

12 Runway Condition Assessment Matrix The new tool airport operators will use to report a runway surface assessment when contaminants are present on paved runway surfaces. (Effective October 1, 2016) RCAM

13 Type TALPA in Search Bar AC No: 150/ D 7/29/2016 Chapter 5

15 Assessment Criteria This section includes contaminant type and depth categories which are objective assessments that have been determined by manufacturers to cause specific changes in aircraft braking performance.

16 Reportable Contaminants Wet (water 1/8 ) Water (> 1/8 ) Frost Slush Ice Wet Ice Wet Snow Wet Snow Over Ice Dry Snow Dry Snow Over Ice Compacted Snow Water over Comp. Snow Wet Snow over Comp. Snow Dry Snow over Comp. Snow Slush over Ice Slippery When Wet Ash Rubber (taxiways only) Oil Sand Mud

17 Runway Condition Description Contaminants, categorized by type, depth, and temperature that directly affect takeoff and landing performance are provided (details).

18 Runway Condition Code RwyCC (6-0) Represent the runway condition description based on defined terms and increments (only applied when >25% overall runway length & width) X/X/X shorthand format; runway divided in touchdown, midpoint, and rollout sections They replace Mu values!!! Applied by pilots to determine landing performance parameters

19 Braking action FAIR is now replaced with MEDIUM

20 Runway Condition Code RwyCC Disseminated via: 1) Federal NOTAM system 1) NOTAM Manager (preferred) 2) ENII System (phasing out) 3) Telephone 2) Airport Traffic Control Tower 3) Flight Service Stations 4) Common Traffic Advisory Frequency

21 Runway Condition Code RwyCC A resultant code of 0 requires runway closure until mitigations are accomplished to increase braking action.

22

23 Downgrade Assessment Criteria To be used when data suggests conditions are worse than indicated by present contaminant. Tools include: 1) Certified Friction Measurement Equipment (CFME)/Decelerometers used for generating legacy Mu values 2) Vehicle Deceleration/Directional Control Observations 3) Pilot Reported Braking Action
