The success of "wildlife strike hazard reduction" measures can be measured in different ways – most simply by the long-term trend in the bird strike rate.
The improvement in the bird strike rate is a reflection of a successful habitat management by the bird strike representative.
Until now the airports have concentrated on area 1 (usually "Landing 200-0 ft., aerodrome and take off 0 – 500ft"), in which wildlife strikes are assigned to the area of responsibility of the airport.
A more detailed definition of the outdoor habitat is given in EU Regulation No. 139/2014 and the remarks relating to ADR.OPS.B.20 wildlife strike hazard reduction.
For many airports the classification of habitats involves additional inspection costs.
The bird strike representative will focus his efforts on the habitats that
a) are relevant for the wildlife strike hazard because of the position of departure and arrival corridors
and
b) in some way provide other starting points for an active habitat management.
There can therefore be different habitats within a radius of 7 NM.
Essentially the aerodrome must specify a procedure for the inspection and evaluation of these habitats, which provides sufficient data quality at a minimal cost. The point-stop method used to measure relative frequency indices is a scientifically recognised and cost-effective procedure.
The point-stop method provides for the inspection of a measurement path, the capture of observations, transfer into a suitable database and subsequent statistical analysis, all of which cost money. Money can potentially be saved by the use of mobile terminals for the counting and classification of species along the measuring paths monitored.
"eControl mobile" provides a touchscreen-optimised user interface specially developed for the purpose of the digital mapping and fully-automatic transfer of data into a database system. The subsequent evaluation and ongoing calculation of indicators such as bird strike rates and frequency indices can occur (semi-)automatically. |
