From page 31...
... 31 This chapter provides a general overview of airport operator input into the EZ-Version WHaMRAT. The relationships between the inputs and the calculations and adjustments made in the WHaMRAT can be visualized using a flowchart (Figure 10)
From page 32...
... 32 Applying an SMS Approach to Wildlife Hazard Management Checklist of Birds of the World (Clements 2007) and Avibase -- The World Bird Database (2015)
From page 33...
... The EZ-Version WHaMRAT 33 Doves/Pigeons, Corvids, and Blackbirds/Starlings guilds based on different flock sizes, with severity increasing as flock sizes increase. In guilds for which flocking behavior is prevalent, a potential increase in severity due to flocking was determined by multiplying average bird mass within a specific guild by flock size and adjusting severity when threshold levels were met.
From page 34...
... 34 Applying an SMS Approach to Wildlife Hazard Management When determining severity for mammals and reptiles, the process was identical to the avian description detailed above. However, threshold levels for severity by body mass for mammals and reptiles vary significantly from those for avian guilds, as aircraft will only encounter these animals (with the exception of bats)
From page 35...
... The EZ-Version WHaMRAT 35 abundance data by species and/or guild reported in a WHA or WHSV, or obtained from other local data sources. If such data do not exist, then the wildlife presence and likelihood values should be determined using abundance data from wildlife identification field guides or handbooks, or via Internet sources such as the USGS Northern Prairie Wildlife Research Center (USGS 2015)
From page 36...
... 36 Applying an SMS Approach to Wildlife Hazard Management • Air Taxi: An aircraft originally designed to have no more than 60 passenger seats or a cargo payload of 18,000 pounds and carries cargo or mail on either a scheduled or charter basis, and/or carries passengers on an on-demand basis or limited-schedule basis (i.e., on four or fewer round trips a week on at least one route according to published flight schedules) only.
From page 37...
... The EZ-Version WHaMRAT 37 identified in FAA AC 150/5200-33B. The user identifies the current presence or absence of such habitats by placing an x in the appropriate habitat row specific to a column indicating its location relative to the airport property.
From page 38...
... 38 Applying an SMS Approach to Wildlife Hazard Management • The effect on wildlife risk decreases as a decay function when the distance from the airport property increases. • Increases in habitat mitigation will decrease wildlife risk, whereas decreases in habitat mitigation will increase wildlife risk.
From page 39...
... The EZ-Version WHaMRAT 39 Future Habitat Mitigation -- Assumptions • An adjustment factor to the Aggregate Wildlife Risk Score is applied in the WHaMRAT based on the cumulative level of documented habitat mitigation practices specific to habitats that are incompatible with aircraft operations. This adjustment can be used to determine a futureprojected Overall Aggregate Wildlife Risk Score.
From page 40...
... 40 Applying an SMS Approach to Wildlife Hazard Management Turf management, combined with additional measures (ranging from non-lethal harassment and deterrence to lethal options) , can have a synergistic effect on wildlife control mitigation and substantiate user-input values of moderate and/or high when all wildlife control and mitigation measures are taken into account.
