The Unmanned Aircraft System
Vertical takeoff and landing (VTOL) aircraft have wings that move in?
A circular motion.
The human element consists of?
A pilot, a sensor, and supporting ground crew.
Lost-link procedures involve creating?
A profile where the mission flight attributes (altitudes, flight path, and speeds) are loaded into the memory of the system prior to aircraft launch.
Fixed winged aircraft are characterized by having wings that stay in?
A static position.
A directional tracking antenna uses the location of a UAS to continuously?
Adjust the direction in which it is pointed in order to direct its signal at the UAS to improve signal strength.
Rapid frequency hopping is a basic signal modulation technique used to spread?
An intended signal across the frequency spectrum by repeatedly switching frequencies during radio transmission to minimize the effectiveness of unauthorized interception or jamming.
Beyond Visual Line of Sight (BVLOS) is the distance beyond which the naked eye cannot?
Detect an aircraft, which is a much shorter distance than radio frequency BLOS.
Line-of-sight (LOS) operations refer to operating an unmanned aircraft via?
Direct radio waves.
Autopilot is the ability for an unmanned system to execute its mission by?
Following a set of preprogrammed instructions without operator intervention.
Regarding fixed wing aircraft, lift is generated by?
Forward movement and air pressure on each wing (airfoil) by using a motor and rotor.
The launch and recovery element (LRE) is one of the most?
Labor-intensive aspects of the UAS operation in which its procedures and dedicated personnel are used to prepare, launch, and recover the UAS
A directional receiving antenna is usually onboard?
Larger aircraft with the aim to further improve signal strength.
Industrial, Scientific, and Medical (ISM) frequency bands can cause the UAS to?
Lose communication with the ground station because of signal interference due to band cognestion.
Beyond line-of-sight (BLOS) operations occur via?
Satellite communications or by using a relay vehicle, such as another aircraft.
Commercial-off-the-shelf systems (COTS) that have autopilot are often characterized as being?
Smaller, lighter, and less expensive in recent years while still offering many of the same operational advantages that large UAS autopilots offer.
An unmanned aircrafts payload can be characterized as?
Surveillance, weapons delivery, communications, aerial sensing, cargo and other application based hardware used during operations.
A data link is?
The UAS command and control information that is sent and received both to and from the GCS and autopilot.
A ground control station (GCS) is a land-or sea-based control center that provides?
The facilities for human control of unmanned vehicles in the air or in space.
Unmanned Aircraft (UA) are operated without?
The possibility of direct human intervention from within or on the aircraft.
