MEMORANDUM FOR A1 - Air Force E-Publishing

66 AFI91-202 5 AUGUST 2011
Supervision and aircrews must thoroughly evaluate mission need before
conducting operations in areas under condition SEVERE.
7.3.1.4.6.2. MODERATE. Wildlife activity near the active runway or other
specific location representing increased potential for strikes. BWC MODERATE
requires increased vigilance by all agencies and supervisors and caution by
aircrews.
7.3.1.4.6.3. LOW. Wildlife activity on and around the airfield representing low
potential for strikes.
NOTE: BWC codes are based on observations of local airfield wildlife activity and are
independent of BAM or Avian Hazard Advisory System (AHAS) risk hazard levels.
NOTE: BWC SEVERE or MODERATE requires action from the installation’s wildlife
dispersal team to reduce the BWC to LOW as soon as possible.
7.3.1.4.7. Designate Phase I and Phase II periods of wildlife activity based on
historical wildlife activity information. Phase II represents times of significant
increases in local wildlife activity, normally associated with migratory movements,
seasonal increases of local wildlife populations, or local land use practices (farming,
ranching, or hunting). Establish flight and scheduling procedures to minimize risks
based on local hazards associated with Phase I and II. Publish Phase I and II
designations in the appropriate DoD Flight Information Publications. Critical updates
may be made using Notice to Airman System.
7.3.1.4.8. Regardless of Phase designation, the highest levels of daily wildlife
activity normally occur +/- one hour of sunrise/sunset as birds move to and from their
roosts. Flight operations should be avoided during these periods unless mission
essential. A risk analysis shall be completed to determine the potential risk to
operations during these periods. Appropriate measures should be taken to mitigate the
risk if required. Maintain a zero tolerance toward large free-roaming animals on or
adjacent to the aircraft movement area (free-roaming animals are, but not limited to,
deer, canines, geese, etc).
7.3.1.4.9. Grass Height. Mow aircraft movement area (AMA) to maintain a grass
height between 7 and 14 inches. The AMA, as defined in UFC 3-260-01, Airfield and
Heliport Planning and Design, is that area of the airfield encompassed by the Primary
Surface and the Clear Zones, as well as apron areas and taxiways, regardless of their
location. As a minimum, turf shall be maintained 500 feet outside the AMA boundary
where able. Installations located in arid climates where growing grass is difficult may
develop natural vegetation on the airfield to limit attractiveness to wildlife. These
situations require comprehensive vegetation/wildlife hazard management and will be
reviewed individually by HQ AFSC/SEFW for approval. Installation safety offices
may request a grass height restriction waiver from HQ AFSC/SEFW after MAJCOM
coordination.
7.3.1.4.10. Technical Assistance. Technical assistance is available through the USAF
BASH Team, HQ AFSC/SEFW, 9700 G Avenue, Suite 266, Kirtland AFB, NM
87117-5670. DSN: 246-5674/5679/5673/1440 or Commercial: (505) 846-xxxx, and
