b.Engine ingestions may result in sudden loss of power or engine failure. Review engine out procedures, especially when operating from airports with known bird hazards or when operating near high bird concentrations. c.Windshield strikes have resulted in pilots experiencing confusion, disorientation, loss of communications, and aircraft control problems. Pilots are encouraged to review their emergency procedures before flying in these areas. d.When encountering birds en route, climb to avoid collision, because birds in flocks generally distribute themselves downward, with lead birds being at the highest altitude. e.Avoid overflight of known areas of bird concentration and flying at low altitudes during bird migration. Charted wildlife refuges and other natural areas contain unusually high local concentration of birds which may create a hazard to aircraft. 7.4.3. Reporting Bird Strikes Pilots are urged to report any bird or other wildlife strike using FAA Form 5200.7, Bird/Other Wildlife Strike Report (Appendix 1). Additional forms are available at any FSS; at any FAA Regional Office or at http://wildlife.mitigation.tc.faa.gov. The data derived from these reports are used to develop standards to cope with this potential hazard to aircraft and for documentation of necessary habitat control on airports. 7.4.4. Reporting Bird and Other Wildlife Activities If you observe birds or other animals on or near the runway, request airport management to disperse the wildlife before taking off. Also contact the nearest FAA ARTCC, FSS, or tower (including non.Federal towers) regarding large flocks of birds and report the: a.Geographic location. b.Bird type (geese, ducks, gulls, etc.). c.Approximate numbers. d.Altitude. e.Direction of bird flight path. Bird Hazards and Flight Over National Refuges, Parks, and Forests 7.4.1 7.4.5. Pilot Advisories on Bird and Other Wildlife Hazards Many airports advise pilots of other wildlife hazards caused by large animals on the runway through the A/FD and the NOTAM system. Collisions of landing and departing aircraft and animals on the runway are increasing and are not limited to rural airports. These accidents have also occurred at several major airports. Pilots should exercise extreme caution when warned of the presence of wildlife on and in the vicinity of airports. If you observe deer or other large animals in close proximity to movement areas, advise the FSS, tower, or airport management. 7.4.6. Flights Over Charted U.S. Wildlife Refuges, Parks, and Forest Service Areas a. The landing of aircraft is prohibited on lands or waters administered by the National Park Service, U.S. Fish and Wildlife Service, or U.S. Forest Service without authorization from the respective agency. Exceptions include: 1.When forced to land due to an emergency beyond the control of the operator; 2. At officially designated landing sites; or 3.An approved official business of the Federal Government. b. Pilots are requested to maintain a minimum altitude of 2,000 feet above the surface of the following: National Parks, Monuments, Seashores, Lakeshores, Recreation Areas and Scenic Riverways administered by the National Park Service, National Wildlife Refuges, Big Game Refuges, Game Ranges and Wildlife Ranges administered by the U.S. Fish and Wildlife Service, and Wilderness and Primitive areas administered by the U.S. Forest Service. NOTE. FAA Advisory Circular AC 91.36, Visual Flight Rules (VFR) Flight Near Noise-Sensitive Areas, defines the surface of a national park area (including parks, forests, primitive areas, wilderness areas, recreational areas, national seashores, national monuments, national lakeshores, and national wildlife refuge and range areas) as: the highest terrain within 2,000 feet laterally of the route of flight, or the upper-most rim of a canyon or valley. c.Federal statutes prohibit certain types of flight activity and/or provide altitude restrictions over designated U.S. Wildlife Refuges, Parks, and Forest Service Areas. These designated areas, for example: Boundary Waters Canoe Wilderness Areas, Minnesota; Haleakala National Park, Hawaii; Yosemite National Park, California; and Grand Canyon National Park, Arizona, are charted on Sectional Charts. d.Federal regulations also prohibit airdrops by parachute or other means of persons, cargo, or objects from aircraft on lands administered by the three agencies without authorization from the respective agency. Exceptions include: 1.Emergencies involving the safety of human life; or 2.Threat of serious property loss. 7.4.2 Bird Hazards and Flight Over National Refuges, Parks, and Forests Section 5. Potential Flight Hazards 7.5.1. Accident Cause Factors a. The 10 most frequent cause factors for general aviation accidents that involve the pilot-in-command are: 1.Inadequate preflight preparation and/or planning. 2.Failure to obtain and/or maintain flying speed. 3.Failure to maintain direction control. 4.Improper level off. 5. Failure to see and avoid objects or obstructions. 6.Mismanagement of fuel. 7.Improper inflight decisions or planning. 8.Misjudgment of distance and speed. 9.Selection of unsuitable terrain. 10.Improper operation of flight controls. b.This list remains relatively stable and points out the need for continued refresher training to establish a higher level of flight proficiency for all pilots. A part of the FAA’s continuing effort to promote increased aviation safety is the Aviation Safety Program.
