  • AAM stands for Advanced Air Mobility. Previously referred to as Urban Air Mobility (UAM), AAM refers to the concept of an air transportation system for people and/or cargo between places. Sometimes referred to as “flying taxis”.
  • BVLOS stands for beyond visual line of sight. The current regulations put out by the FAA regarding drones is called Part 107, one of the major rules outlined in Part 107 is that you cannot fly your drone farther than you can physically see it.
  • DAA stands for Detect and Avoid – systems that provide situational awareness to an aircraft that enable the identification of other air traffic or hazards and the ability to take appropriate action to mitigate collision risk.
  • eVTOL stands for electric vertical take-off and landing. An eVTOL aircraft uses electric power to hover, take off, and land vertically.
  • UAM stands for Urban Air Mobility. UAM refers to the concept of an air transportation system for people, sometimes referred to as “flying taxis”. In March 2020, NASA stated that Urban Air Mobility has advanced so much that it was decided Advanced Air Mobility (AAM) was a better term to use going forward.
  • UAV stands for unmanned aerial vehicle or uncrewed aerial vehicle commonly referred to as a drone – the actual aircraft being piloted by remote control or onboard computers.
  • UTM stands for UAS Traffic Management. Much like there is an Air Traffic Management (ATM) system for manned aircraft, UTM is a traffic management system being developed to support unmanned aircraft. Four key technologies that will enable UTM include UAS Service Suppliers, drone tracking and remote identification, vehicle-2-vehicle communication, and detect and avoid sensors.
  • A Vertiport is an identifiable ground or elevated area, including any buildings or facilities thereon, used for the takeoff and landing of VTOL aircraft and rotorcraft.
  • A Pilot in Command (PIC) is an individual, human person who has final authority and responsibility for the operation and safety of flight and holds the appropriate licenses and qualifications to conduct the flight.
