What is the Unmanned Aircraft System?
UAS is the term introduced by the Federal Aviation Administration (FAA) & adopted by United States Department of Defense (DOD) & Civil Aviation Authority(UK).Detects fire with infrared imaging sensors High altitude aircraft controlled by personnel on ground. Generally used for scientific/commercial research missions

History of the UAS• The earliest unmanned aerial vehicle
was Hewitt-Sperry Automatic Airplane after World War 1.
• Initially used for military and national defense.
• Over the years technology has been a major contribution to the unmanned aircraft work in progress.
• The modern Remote Piloted Vehicle (RPV) era began in 1959.

Introduction of UAS
• It consist of Unmanned Aircraft(UA), the Control System & other related support equipment.
• It also called Unmanned Aerial Vehicle(UAV),Drones, Remotely Piloted Vehicle (RPV).
• Example:- RQ-7 SHADOW, RQ-5HUNTER, RQ-11 RAVEN etc.
• They can perform an increasingly sophisticated array of missions due to their small size and decreased radar.

How UAS Works
• Collects Data• Processes it into images• Sends images via satellite to fire
command centers
![Page 7: What is the Unmanned Aircraft System Final Ppt](https://reader035.vdocuments.us/reader035/viewer/2022062219/5525137a4a79599d488b4a38/html5/thumbnails/7.jpg)
Purposes for UAS
• Firefighting• Police Disturbances (crime scenes,
etc)• Reconnaissance Support in natural
disasters ie: hurricanes, mudslides• Surveillance (in war zones)• UAS systems often preferred for
missions that are too “dull, dirty or dangerous” for manned aircraft.

UAV classification
• Target and decoy - providing ground and aerial gunnery a target that simulates an enemy aircraft or missile
• Reconnaissance - providing battlefield intelligence • Combat - providing attack capability for high-risk
missions• Logistics - UAVs specifically designed for cargo
and logistics operation • Civil and Commercial UAVs - UAVs specifically
designed for civil and commercial applications

An Unmanned System isa Network-Enabled System
• Multiple vehicle control with single operator• Communications (connectivity, bandwidth)
![Page 15: What is the Unmanned Aircraft System Final Ppt](https://reader035.vdocuments.us/reader035/viewer/2022062219/5525137a4a79599d488b4a38/html5/thumbnails/15.jpg)
UAS Applications
• Weather Reconnaissance• Aerosonde UAS currently in use for Weather
Reconnaissance• Civil applications : Forest fire detection,
pollution detection, agriculture, fishing, etc...
• Localized Surveillance• Traffic Helicopter: e.g. Bell JetRanger
![Page 16: What is the Unmanned Aircraft System Final Ppt](https://reader035.vdocuments.us/reader035/viewer/2022062219/5525137a4a79599d488b4a38/html5/thumbnails/16.jpg)
What is Autonomy?• Recent emerging field
• Ability to make decisions without human intervention
• Goal: tech machines to be “smart” and act more like humans.
![Page 17: What is the Unmanned Aircraft System Final Ppt](https://reader035.vdocuments.us/reader035/viewer/2022062219/5525137a4a79599d488b4a38/html5/thumbnails/17.jpg)
How is UAS better than other methods ?
They can perform an increasingly sophisticated array of missions due to their small size and decreased radar, acoustical, and infrared signatures.
• Maximum flight hours 30+• 3000lb fuel capacity• Fly above 52,000ft• Operate at night• Above Smoke
• With a continuing trend of miniaturization in electronics and other components, the RPV can be made much smaller and cheaper

2015 and Beyond
UAS operations dominate some aviation sectors
–Particularly those “dirty, dull or dangerous” Commercial UAS applications steadily grow
–Driven by “business cases” for reduced cost
Consumers becoming increasingly receptive to reduced human presence in aircraft.–Passenger flights with a single “supervisory” pilot–Cargo operations without an on-board pilot
![Page 19: What is the Unmanned Aircraft System Final Ppt](https://reader035.vdocuments.us/reader035/viewer/2022062219/5525137a4a79599d488b4a38/html5/thumbnails/19.jpg)
More Benefits to Autonomy field
• High Reliability–Control system
• Helps prepare maps to assist in planning efforts
• Undetected at high altitudes.
• In fires: is able to fly above path of air tankers and helicopters fighting fire below.

Interesting Facts• In UK, BAE Systems
announced UAS to be used for police/coastal work as soon as 2012
• National Oceanic Atmospheric Administration began using “Aerosonde” UAS as “Hurricane Hunter”

Alternative Uses for UAS
• Predicting weather• Go into hurricanes (above) for quick information
• Track air pollution
![Page 23: What is the Unmanned Aircraft System Final Ppt](https://reader035.vdocuments.us/reader035/viewer/2022062219/5525137a4a79599d488b4a38/html5/thumbnails/23.jpg)
Emerging Opportunities
• Missile Defense– Providing earlier
launch detection and tracking to improve intercept opportunities
• Battlefield Communications– Enabling reliable, secure
direct communications with global maritime forces

ConclusionUAV Systems are newcomers in
the Air Traffic
Developments made for UAV Systems (automatic modes, enhanced situation awareness, ...) might reciprocally be beneficial to other civil aviation applications.
