Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

124 B.1 Snow and Ice Removal • Snow Removal Equipment Runway Occupancy Time—The duration that a runway is closed to aircraft while occupied by SRE and friction testing equipment (22, p. 24). • Runway Closure Duration—The duration a runway is closed due to winter weather-related surface conditions and snow removal operations. • Follow-up Friction Measurement Value—The results of a friction test after snow and/or ice removal and/or chemical and/or sand application operations, and an indicator of snow and/ or ice removal and chemical application effectiveness. • Time to Complete Airside Priority 1 Pavement—The time it takes to complete clearing the specified areas that are defined within an airport’s SICP as priority 1 areas. Similar to runway occupancy time, but extends beyond the performance of clearing the runway. • Hours Runway is Available—The total number of hours that the runway is available during a specified period (e.g., winter event). Opposite of Runway Closure Duration. • Missed Runway Reopening Time—Occurs when the coordinated runway reopening time between the airport and ATC is not met due to a longer than anticipated runway occupancy time by SRE. • Signage/Lighting/Infrastructure Damage—A measure of airport documented damage of key infrastructure caused by SRE. Indicates the level of equipment operator situational awareness and training, as well as equipment effectiveness. • Fuel Usage—The volume of fuel used for winter event operations over a specified period. Indicates the efficiency of SRE operation and area cleared. • Airport Entrance to Terminal Passenger Travel Time—The average time it takes for a passen- ger to travel from the main airport entrance to the terminal. Indicates the condition of landside roadways and the effectiveness of landside winter operations. • Time to Complete Airside Non-priority 1 Pavement—The time it takes to clear airside areas that are not identified as priority 1 surfaces. • Time to Complete Landside Pavement—The time it takes to complete clearing the specified areas of the airport that are not part of the aircraft operating area, including terminal buildings, roadways, parking lots, and garage decks. B.2 Chemical and Sand Application • Unit Volume/Mass Applied per Unit Area Treated—The unit volume or mass of material and/or chemical applied per the unit surface area treated. B.3 Equipment • Snow Removal Equipment Maintenance Down Time—The total time a piece of SRE is not in operation due to maintenance requirements. A P P E N D I X B Example Airport Performance Indicators

Example Airport Performance Indicators 125 • Snow Removal Equipment Operation and Maintenance Cost—The operation and mainte- nance cost for the SRE fleet over a specified time period (22, p. 168). • Snow Removal Equipment Average Age—The average age of airport SRE based on type. This can be an age assessment by year manufactured, miles driven, or hours of operation. • Snow Removal Equipment Age—The age of airport SRE based on type. This can be an age assessment by year manufactured, miles driven, or hours of operation (22, p. 162). • Snow Removal Equipment Maintenance Labor Cost—The total cost of labor directly associated with maintaining SRE over a specified period. • Snow Removal Equipment Airside Operator Labor Cost—The total cost of part-time and full-time airport labor employed to operate airside SRE during the winter season. • Snow Removal Equipment Landside Operator Labor Cost—The total cost of part-time and full-time airport labor employed to operate landside SRE during the winter season. • Snow Removal Equipment Fleet Operating Speed—The average travel speed of the SRE fleet while in operation. Speeds may be identified for varying groups assigned different functions (e.g., runway teams, taxiway teams, etc.). B.4 Safety • Aircraft Excursions—The number of times an aircraft goes off dedicated pavement surfaces due to surface conditions during a winter season. • Snow Removal Equipment Incursions—The number of times that there is an incorrect presence of a snow removal vehicle or operator on a runway that is open for aircraft operations (22, p. 215). • “NIL” Pilot Braking Action Report—The number of occurrences when braking action con- ditions indicating that the degree of braking is zero on the airport movement area is reported by pilots within a pilot report. • Aircraft Snow Damage Incident—The number of incidents over a specified time period for which an aircraft is damaged due to the results of pavement snow removal operations, such as snow piles scraping the tips of an aircraft wing, or landing gear damaged by windrows (22, p. 226). • Snow Removal Equipment Damage Incident—The number of incidents where a piece of SRE is damaged while in operation over a specified time period (22, p. 226). • Snow Removal Equipment Operator Windshield Time—The total amount of time a snow removal operator spends operating equipment during an event. • Annual Snow Removal Equipment Operator Training Hours—The total training hours received per operator over a calendar year or winter season. B.5 Stakeholder Coordination • Time between Runway Reopening and First Aircraft Operation—The amount of time after all snow removal and friction testing equipment has left a runway cleared to be reopened and the first aircraft operation. • Missed Approach/Go Around—The number of occurrences when a pilot is directed by ATC to abandon his/her approach to landing due to a longer than anticipated runway occupancy time by SRE. • Missed Holdover Times/Repeat Deicing—The number of occurrences when an aircraft exceeds its deicing holdover time and must repeat deicing because of taxiway or runway unavailability caused by snow/ice accumulation or active snow removal operations. • Taxi-Out Time—The average time to taxi from gate to runway end (22, p. 25). • Taxi-In Time—The average time to taxi from runway end to gate. • Percent Arrival Flights Delayed—The percent of arriving flights delayed by 15 or more min- utes due to airport winter operations (22, p. 233). • Percent Departure Flights Delayed—The percent of departing flights delayed by 15 or more minutes due to airport winter operations (22, p. 235).

126 A Guidebook for Airport Winter Operations B.6 Financial • Cost/Unit Depth of Snow—The sum of applied runway chemical and material costs, labor costs (including regular and premium pay), contractor costs for both equipment and labor, cost of fuel used by the equipment, and costs associated with the snow melting operation (excluding operating or amortized capital cost of equipment) incurred during a snow event, divided by the unit depth of snow per event. • Cost/Unit Area Cleared—The sum of applied runway chemical and material costs, labor costs (including regular and premium pay), contractor costs for both equipment and labor, cost of fuel used by the equipment, and costs associated with the snow melting operation (excluding operating or amortized capital cost of equipment) incurred during a snow event, divided by the surface area cleared during the event. • Contract Labor Cost—The total cost of contractor labor for winter operations services during a winter event or over the winter season. B.7 Environmental Compliance • Permit Violations—The number of exceedances of permitted numeric limits for environmental protection, such as in a NPDES permit.
