  • Chapter 3: Identifying Hazards & Associated Risks › Environmental Hazards › Facilities

    Facilities The departure and arrival facilities pilots use contain various hazards, and these can be aggravated by other environmental factors. • Airports–Runway dimensions may not be sufficient such that a takeoff or landing can be performed safely under the given ... conditions. • Runway Contamination–Wet or snow-covered runways are an environmental hazard. Some airplane flight manuals (AFM) provide little or no guidance on how to modify takeoff and landing distances for contaminated runways. • Heliports–The aircraft rotor diameter may exceed…

  • 2 Aviation Weather Service Program › 2.2.1 National Environmental Satellite, Data, and Information Service (NESDIS) › 2.2.1.1 Satellite Analysis Branch (SAB)

    National Environmental Satellite, Data, and Information Service (NESDIS) NESDIS manages the U.S. civil operational remote-sensing satellite systems, as well as other global information for meteorology, oceanography, solid-earth geophysics, and solar-terrestrial sciences. NESDIS provides this data ... NESDIS’ Satellite Analysis Branch (SAB) serves as the operational focal point for real-time imagery products and multidisciplinary environmental analyses. The SAB’s primary mission is to support disaster mitigation and warning services for the U.S. Federal agencies…

  • Chapter 11. Unmanned Aircraft Systems (UAS) › Section 8. Other Information and Best Practices › 11-8-6. Environmental Best Practices

    Environmental Best Practices a. Unmanned aircraft operate in a similar environment to manned aircraft. Since most UAS operations are conducted at low altitude, hazards, risks and potential environment factors may be encountered on a more frequent basis. In addition ... avoid prolonged or repetitive flight at low altitude near noise sensitive areas. (b) As described in FAA Order 1050.1, Environmental Impact: Policies and Procedures, an area is “noise sensitive” if noise interferes with any normal activities associated with the area…
