  1. When working with radio frequency, LOS and BVLOS:
  2. One of the major advantages to _____ is that it utilizes long wavelengths that can pass through most cloud layers, smoke, and dust in the atmosphere.
  3. _________ is the term used to describe how the UAS command and control information is sent and received both to and from the GCS and autopilot.
  4. ____________ aircraft are vehicles where the lift is created by induced airflow over wings that are affixed to fuselage of the aircraft.
  5. COTS stands for ______ ______ ______ ______; COTS is a widely used acronym for many different technologies)
  6. SAR systems use ______________ to create highly detailed imagery of the ground.
  7. Autopilot equipment is designed to:
  8. These sensors generate an image using thermal radiation emitted from every object.
  9. Biomass, crop health, crop yield, and other plant characteristics can be estimated from remotely sensed data using a _________ Index
  10. As a safety feature of most UAS autopilots, the system can perform a “_________” procedure if communication becomes severed between the ground control station and the air vehicle.
  11. These UAS platforms have the advantage of small take off and landing footprints.
  12. _________ cameras are most frequently operated during daylight hours for optimal video quality.
  13. A cooled ___________ camera’s detectors are typically located in a vacuum sealed case and require extra power to cool. In general, cooled cameras produce a higher quality image than uncooled cameras.
  14. Some of the most common LRE types involve using a ______________ system to get the aircraft to flight speed in a very short distance.
  15. What is orthorectification?
  16. ______ can be used to create highly detailed 3D point clouds that can be used to recreate an object in three dimensions.
  17. Which of the sensors below are considerd optical sensors?
  18. ___________ sensors are those that emit some form of electromagnetic (EM) radiation that is directed at a target and then measures the reflected signal.
  19. A laser range finder uses a laser beam to determine the __________    _____ an object. A laser designator uses a laser beam to designate a target.
  20. Manufacturers of some sUAS have elected to accommodate interchangeable __________ that can be quickly removed and replaced.
  21. The disadvantages of small electric helicopters are that _______ technology to date has not enabled long endurance to be achieved beyond 30 to 60 minutes.
  22. A brief Internet search will yield numerous current and emerging examples of ___________ programmable automated controllers for a variety of unmanned vehicles, not limited to air.
  23. These systems send out a pulse and use the reflected signal and the receiver’s motion to construct a 2-D or 3-D image of the returning echoes.
  24. Geospatial imagery is often georectified after a flight.  What is georectification?
  25. One of the foremost goals for future UAS operation will be the capability for one crew to operate ______ aircraft from one GCS, however many challenges remain before this concept can be safely integrated into the NAS.
