Route manual: winter ops

Question 1

Contaminated Runway Operations definition

Answer 1

• > 25% rwy length and width
• standing water, slush or snow
• Not sure request performance penalty
• 3mm =1/8 inch or 0.13 inches

Question 2

Runway Contamination Levels

Answer 2

• 3 levels for standing water, slush, wet snow, dry snow, compact snow
• Take off selected IAW to levels
• > level 3 is prohibited
• Compact snow 100% covered is contamination

Question 3

Wet Runways

Answer 3

• still less than contamination level
• significant areas of standing water
• DAMP rwy is not contaminated
• use Pilot judgement

Question 4

Grooved Runways

Answer 4

• provide additional drainage so DRY
• when in doubt use WET
• ATIS wet use WET

Question 5

Minimum Runway width

Answer 5

• 147 feet (45 meters)
• contamination min 100 ft needs to be used

Question 6

Global Reporting Format for Runway Surface Conditions (RWYCC)

Answer 6

• using RCAM gives a code
• 0 extremely slippery to 6 complete dry
• Notams

Question 7

Runway Condition Assessment Matrix (RCAM)

Answer 7

• assessment criteria and downgrade assessment criteria
• codes see Route

Question 8

RWYCC Contaminated Runway Crosswind Tables

Answer 8

• xwind limits
• FO <4 not allowed to land
• ENG t/g and L/g apply
• take off 1 or below not allowed
• manual table

Question 9

Takeoff Anti-Ice Setting TRS/ACARS Flow Chart

Answer 9

• ENG anti ice = 5C - 10C, visible moisture, Prec upto 1700 AGL, WET/ contamination
• ALL anti ice = < 5C, visible moisture, Prec upto 1700 AGL, WET/contamination

Question 10

De-icing Procedures General

Answer 10

• deice checklist from after start
• sure weather app: TYPE 1 and TYPE 4 + Times
• Bleeds off
• 1 truck: Type 1 applied then Type 4
• chipping is prohibited
• Removing them by hand, soft brush,forced air or de-ice fluid is permitted
• cold temps consult LOUT of the fluid cant below LOUT check route
• do not confuse with freezing point with LOUT

Question 11

Holdover Time Hierarchy

Answer 11

• if app does not work: ACARS, snowfall intensity vs visibility chart, METAR
• pilot judgement
• Porter Deicing app section route manual

Question 12

Holdover Time Determination System (HOTDS)

Answer 12

• CYYZ, CYOW, CYHZ, CYULand CYVR
• snow chart nor required
• ACARS

Question 13

Winter/Contaminated Runway Operations Overview Departures Preparation for departure

Answer 13

• REF: route manual and sure WX
• RWYCC code and Contaminant name
• Level
• Max xwind table
• DE ice
• CONTAM Take off numbers
• Hold over time
• No app use HOTDS
• snowing chart

Question 14

Assessment of Multiple Contaminants

Answer 14

• Sum >25%
• wet ice > 25% or CRFI <0.2 T/O Prohibited
• Use most restricted for T/O numbers with RCAM
• FICON if divided use the 3rd contaminant
