TALPA ARC Recommendations Methods for assessing runway conditions Reporting of braking action by pilots Reporting of runway conditions through airport operators, the NOTAM system, and ATC agencies Airplane performance data Before landing/departing performance assessments Standardized condition reports terms 5

Winter Season Validations First Validation Winter 2009-2010 Second Validation Winter 20102011 7
Changes Already In Effect 2008 AC Changes (Closure triggers, friction testing subjectivity) Published Reportable Contaminant List Standardized terminology and reporting methods Expanded NOTAM System for filing Field Condition (FICON) NOTAMs – Sortable FICON Information for end users – Domestic and International Compatibility – Real-time / Instantaneous reporting. 8
When is the RCAM Applicable? Only on Paved Runways – Not on Turf, Dirt, Gravel, or Water Runways, Codes are NOT generated on Taxiways, Ramps, Heliports, etc Codes are generated when the total runway surface or cleared width is more than 25% contaminated (automatically calculated by FNS) 9

Runway Condition Codes Why is it better than Mu? Less subjective More substantive What does it mean to the Pilot? Type and depth of contaminant(s) Estimated aircraft braking action to be anticipated Targeted and more computable performance data 18
Related Changes 2016 - 2017 Season NOTAM System will serve as the primary method for disseminating field condition information / FICON NOTAMs No longer reporting friction values (Mu) No longer reporting vehicle braking for runway condition Acceptable for low-speed environments (taxiways, ramps etc.) Percentage based reporting Reporting runway conditions in thirds 19
10% 10% or less 20% 11% thru 20% 25% 21% thru 25% 30% 26% thru 30% 40% 31% thru 40% 50% 41% thru 50% 60% 51% thru 60% 70% 61% thru 70% 75% 71% thru 75% 80% 76% thru 80% 90% 81% thru 90% 100% 91% thru 100% Reporting Runway Conditions in Thirds 27 Range 9 Coverage 20
Reporting Airport Condition Information Runway Condition Codes are disseminated via one or more of the following methods: – Federal NOTAM System, preferably through NOTAM Manager or equivalent system(s); – Air Traffic Control Facility (corresponding Tower, Center, Tracon, etc.); – Flight Service Station (FSS) (as applicable); and – Directly from airport operator via Common Traffic Advisory Frequency (as applicable) 21
CURRENT SYSTEM - FUTURE SYSTEM 22
NOTAM Manager 23
E-NOTAM II 24
Let’s Issue a NOTAM using the RCAM Rules 25
Changes to NOTAM Manager Entire Runway No SFC Condition Option 26
Changes to NOTAM Manager Directiona l Runway SFC Condition Option 27
Changes to NOTAM Manager Similar entries except 3 parts of RWY, and must select % coverage 28
Changes to NOTAM Manager % Coverage table for each 1/3rd RWY 29
Changes to NOTAM Manager You must select Add Contaminant to populate in NOTAM -Can add multiples Note RwyCC in If the next 1/3 NOTAM & conditions for each of the RWY contains the 1/3 of RWY same Contaminant, you can just select Copy Automatically assigns RwyCC for each 1/3 RWY 30
Changes to NOTAM Manager Conditions reported without RwyCC If overall length and Note RwyCC in width of RWY NOTAM & has less thanconditions for each 25% coverage, 1/3 of RWY no RwyCC will be generated (average of 3 sections 25% Automatically or for less) assigns RwyCC each 1/3 RWY No RwyCC Calculated 31
Changes to NOTAM Manager When average of 3 sections is 25%, NM automatically generates RwyCC for each 1/3 RWY RwyCC is in NOTAM & conditions for each 1/3 of RWY RwyCC can be downgraded by using data in RCAM Table and Airport Operator Judgment 32
Changes to NOTAM Manager 33 When RwyCC is a 0 or a 1, they can be upgraded (not higher than 3) if specific circumstances exist involving ice or compacted snow (a 2 cannot be upgraded since the only contaminants that generate a 2 are water and slush.)
Changes to NOTAM Manager 2. Verify conditions required to upgrade RwyCC 1. Enter desired upgraded Code, not above 3 34
Changes to NOTAM Manager Once conditions are verified, select OK 35
Changes to NOTAM Manager Upgraded RwyCC in NOTAM 36
Center Portion of RWY DRY Note upgraded RwyCC in NOTAM If center portion of RWY is DRY: 1. Enter each 1/3rd as 100% DRY 37
Center Portion of RWY DRY 2. Enter the width in feet of the DRY portion of the RWY 4. Review NOTAM language for accuracy 3. Enter condition of remainder of RWY 38
Rest of NOTAM Editor Unchanged This portion of the NOTAM Editor page remains unchanged 39
Pilot Reported Braking Action Feature Information does not go into NOTAM, but into Archive Report – also justification for downgrading RwyCC The remainder of the NOTAM Editor page remains the same 40
Changes to ENII 2 Options Added: RWY Surface Condition RWY Slippery When Wet 41
Changes to ENII To create a Surface Condition NOTAM – you must first select a RWY option RWY Keyword auto fills Only Directional RWYs are listed Conditions are to be entered in thirds 42
Changes to ENII Must select % Coverage, Depth, and Contaminant for each RWY 1/3rd 43
Changes to ENII You must select Add Contaminant to populate in the NOTAM – can enter 2 conditions per RWY 1/3rd If the next 1/3 of the RWY contains the same Contaminant, you can select Copy To delete an existing entry click the trash can icon 44
Changes to ENII If overall length and width of RWY has less than 25% coverage, no RwyCC will be generated (average of 3 sections 25% or less) Conditions reported without RwyCC No RwyCC Calculated 45
Changes to ENII Warning message will appear if total coverage range is less than 25% 46
Changes to ENII When average of 3 sections is 25%, NM automatically generates RwyCC for each 1/3 RWY RwyCC is in NOTAM and conditions for each 1/3 of RWY RwyCC can be downgraded by using data in RCAM Table and Airport Operator Judgment 47
Changes to ENII When RwyCC is a 0 or a 1, they can be upgraded (not higher than 3) if specific circumstances exist involving ice or compacted snow (a 2 cannot be upgraded since the only contaminants that generate a 2 are water and slush.) 48
Changes to ENII 2. Verify conditions required to upgrade RwyCC 1. Enter desired upgraded Code, not above a 3 49
Changes to ENII Must type in MU value Once conditions are verified, select OK 50
Changes to ENII Upgraded RwyCC in NOTAM 51
Center Portion of RWY DRY If center portion of RWY is DRY: 1. Enter each 1/3rd as 100% DRY 52
Center Portion of RWY DRY 2. Enter the width in feet of the DRY portion of the RWY 3. Enter condition of remainder of RWY 4. Review NOTAM language for accuracy 53
Pilot Reported Braking Action Feature Information does not go into NOTAM, but into Archive Report – also justification for downgrading RwyCC 54
RCAM Driven NOTAM Examples Uniform Coverage example: !ORD XX/XXX ORD RWY 04L FICON 5/5/5 50 PRCT 1/8IN DRY SN . 1604251625-1604261625 Different Contaminants In Each Third: !ORD XX/XXX ORD RWY 04L FICON 5/3/5 50 PRCT WET, 50 PRCT 1/8IN WET SN OVER COMPACTED SN, 50 PRCT 1/8IN SLUSH . 1604251625-1604261625 Two Different Contaminants In Each Third: !ORD XX/XXX ORD RWY 04L FICON 3/5/2 50 PRCT WET AND 50 PRCT 1/8IN WET SN OVER COMPACTED SN, 50 PRCT WET AND 25 PRCT 1/8IN WET SN OVER COMPACTED SN, 10 PRCT 1/4IN SLUSH OVER ICE AND 75 PRCT 1/4IN SLUSH . 1604251625-1604261625 55
Reporting Wet Runway WET: Visible dampness, or water that is 1/8-inch or less in depth on the runway. – No RwyCC if 25% coverage just a Wet Runway NOTAM – Change due to the airplane performance differences that exists between wet, dry, or runways with water greater than 1/8-inch in depth – Year round reportable runway surface condition – NOTAM system enables users to establish a reoccurring template 56
What is Slippery When Wet? Slippery When Wet: Pavement maintenance evaluation indicates the averaged Mu value on the wet pavement surface is below the minimum friction level classification specified in AC 150/5320-12, Measurement and Maintenance of Skid-Resistant Airport Pavement Surfaces – Contributing factors that can create this condition include rubber buildup, groove failures/wear, and pavement macro/micro textures – Slippery When Wet NOTAM generates RwyCC of 3/3/3 The entire runway is considered “Slippery When Wet” if any portion of the runway fails to meet the minimum friction criteria per the AC guidance. Downgrades available based on airport operator judgment No upgrades allowed NOTAM issued anytime the runway is “Wet” and the degraded friction condition exists. 57
Examples: Aircraft Operator Side 58
Airbus ROPS and TALPA In flight, predicted stopping point based on TALPA ARC recommendations Includes 15% operational safety margin On A350, can select runway condition by either runway surface description or braking action On ground, predicted stopping point transitions to being based on actual deceleration being achieved In-flight landing distance check required to ensure alerts will not trigger during a normal approach 59
