Questions and Answers
One of the leading issues facing UAS integration and proliferation is the lack of parts standardization and system reliability.
True
How would you define the physical aspects of a small unmanned aircraft (UA) to a friend?
A UA weighs less than 55 pounds, including everything onboard or attached to the aircraft.

Study Notes
UAS Overview
- Lack of parts standardization and system reliability are major issues in UAS integration.
- Small unmanned aircraft (UA) weigh less than 55 pounds including onboard components.
- The term "Unmanned Aircraft System" encompasses all UAS components, not just the air vehicle.
UAS Components and Personnel
- Essential components of a UAS: unmanned aircraft, payload, control station, and control link.
- The Visual Observer (VO) aids the Remote Pilot in Command (RPIC) during operations.
Technology and Performance
- Key technology issues for UAS integration: reliability, detect and avoid technology, and control link security.
- Aircraft performance is influenced by density altitude and increases as air density decreases.
- Air density decreases with rising temperature and altitude, affecting performance.
Launch and Flight Dynamics
- For sUAS launches, the vehicle should be launched into the wind to enhance stability.
- Humidity increases air density, negatively impacting performance.
Flight Characteristics
- Four forces acting on an aircraft in flight: lift, weight, thrust, and drag.
- Rotary-wing aircraft can take off and land vertically, unlike fixed-wing aircraft which rely on thrust for lift.
Navigation and Control
- Accurate navigation is provided by Global Positioning System (GPS).
- If a UA is overweight, expect reduced maneuverability.
First-Person View (FPV) Regulations
- A First-Person View (FPV) camera can satisfy "see and avoid" requirements if a Visual Observer maintains visual contact with the aircraft.
Aircraft Types and Movement
- Fixed-wing UAS perform best with internal combustion engines.
- The elevator controls movement around the lateral axis of fixed-wing aircraft.
- Unmanned aircraft can navigate through three-dimensional space with six degrees of freedom.
Aerodynamics and Flight Mechanics
- The increase in lift and drag forces raises the angle of attack (AOG) of an airfoil.
- Aerodynamics is the study of forces and motion of objects moving through air.
- A servo is an electro-mechanical device that operates a control surface.
Advantages of Rotary-Wing Aircraft
- Key advantages of rotary-wing aircraft include hovering flight capability and Vertical Takeoff and Landing (VTOL) abilities.
