Above Ground Level (AGL) - ANSWER Height above the ground over which you're flying Advisory Circular - ANSWER Type of publication offered by the Federal Aviation Administration (FAA). Unless they're incorporated into a regulation by specific reference, ACs are issued to inform the public of nonregulatory material and are not binding. Aeronautical Advisory Stations (UNICOM). - ANSWER Air to ground communication facility employed at airports with a low volume of general aviation traffic and where no control tower is active. Aeronautical Decision Making (ADM) - ANSWER Systematic mental approach to consistently determine the best course of action in a given situation Aeronautical Information Manual (AIM) - ANSWER Federal Aviation Association (FAA) official guide to basic flight information and Air Traffic Control (ATC) procedures. Aeronautical Knowledge Test. - ANSWER Federal Aviation Association (FAA) exam required to become a Remote Pilot in Command (PIC) for a Small Unmanned Aircraft System (sUAS). Air Traffic Control (ATC). - ANSWER Responsible for providing the safe, orderly, and expeditious flow of air traffic at airports where the type of operations and/or volume of traffic requires such a service. Airmen's Meteorological Information (AIRMET) - ANSWER Weather advisory that contains information about weather events that are potentially unsafe. Compared to SIGMETs, AIRMETs cover less severe weather. Automated Surface Observing System (ASOS - ANSWER Weather reporting system that provides surface observations up to the minute via digitized voice broadcasts and printed reports Automated Terminal Information Service (ATIS) - ANSWER Continuous broadcast of recorded aeronautical information in busier airports. Contain essential information such as weather information, active runways, available approaches, and NOTAM. A+ Automated Weather Observing System (AWOS). - ANSWER Weather reporting system that consists of various sensors, a processor, a computer-generated voice subsystem, and a transmitter to broadcast weather data on a minute-by-minute basis. Aviation Area Forecast (FA) - ANSWER Encompasses the weather conditions over a large regional area. Beneficial in verifying airport conditions at airports that do not have terminal aerodrome forecasts. Aviation Routine Weather Report (METAR). - ANSWER Observation of current surface weather reported in a standard international format. Issued hourly unless significant weather changes have occurred. B4UFly App - ANSWER Smartphone app from the Federal Aviation Association (FAA) that helps unmanned aircraft operators determine whether there are any restrictions or requirements in effect at the location where they want to fly. Center of Gravity (CG). - ANSWER The point at which your aircraft would perfectly balance if it were suspended at that point. Certificate of Waiver (CoW). - ANSWER Allows a Small Unmanned Aircraft System (sUAS) operation to deviate from certain provisions of Part 107 as long as the FAA finds that the proposed operation can be safely conducted under the terms of that Certificate of Waiver. Certificate of Waiver or Authorization (COA) - ANSWER Applies only to public operators (government entities and organizations). Permits nationwide flights in Class G airspace at or below 400 feet, self-certification of the Small Unmanned Aircraft System (sUAS) pilot, and the option to obtain emergency COAs (e-COAs) under special circumstances. Chart Supplement U.S. (formerly Airport/Facility Directory). - ANSWER Provides the most comprehensive information on a given airport. Contains information on airports, heliports, and seaplane bases that are open to the public. Published across seven books, and the information in each of these books is updated every couple of months. Common Traffic Advisory Frequency (CTAF) - ANSWER Frequency designated for the purpose of carrying out airport advisory practices while operating to or from an airport without an operating control tower. Control Station (CS) - ANSWER An interface used by the remote pilot in command or the person manipulating the controls to control the flight path of the Small Unmanned Aircraft System (sUAS). (In basic terms, this is your remote control.) Corrective Lenses - ANSWER Spectacles or contact lenses.
