GPS – Global Positioning System
Grid Flight Pattern - An aerial sketch mapping technique where the aircraft flies straight in cardinal directions in a back and forth pattern.
Helicopter - A rotorcraft that for its horizontal motion depends on its engine driven rotors.
IFR - Instrument Flight Rules. A type of flight plan that is required when the basic weather is less than 3 miles visibility, a 1,000 ft. ceiling and the aircraft cannot remain clear of the clouds. Special aircraft and pilot certification is required.
Incident -An occurrence out of the normal realm of every day operations and may have the potential to lead to an accident.
Instrument Flight - Flight made by the sole reference to instruments inside the aircraft. Special pilot and aircraft certification is required to accomplish flight by reference to instruments. See IFR.

Large Aircraft - Aircraft of more than 12,500 pounds maximum certified takeoff weight.
Light Aircraft - Aircraft of less than 12,500 pounds maximum certified takeoff weight.
Light Helicopter - A helicopter with a maximum gross takeoff and landing weight of 6,000 pounds and below.
MOA – Military Operations Area. Areas established to contain certain military activities such as air combat maneuvers, intercepts, and acrobatics.
MTR - Military Training Route. Designated routes utilized by the Department of Defense for military training. Aircraft are often in close proximity to the ground.
Medium Helicopter - A helicopter with a maximum gross takeoff and landing weights from 6,001 to 12,500 pounds.
Overview Survey – A landscape-level assessment of symptoms caused by insects, diseases and abiotic factors, usually performed on an annual basis.
PWP – Project Work Plan. Outlines the purpose, procedures, participants, operations, safety, and communications of a particular project.
Pest Signature – Tree damage or recent tree mortality due to an insect, disease, or abiotic event, that is visible from the air. The resulting color and/or pattern change often provides clues as to which specific agent is causing the tree damage or mortality.
Pilot in Command - The pilot responsible for the operation and safety of an aircraft and its occupants during flight.
Polygon – The shape drawn on the sketch map delineating a corresponding area on the ground having insect, disease, or abiotic activity. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：AVIATION OPERATIONS AND ACCIDENT PREVENTION PLAN(17)
