- Q1
The Aerosonde is a small UAV designed
for stealth surveillance
for gathering communications intelligence
to collect weather data over oceans and remote areas
for the reconnaissance role
30sEditDelete - Q2
This vehicle communicates the results of the mission, e.g. photographs,are usually obtained from it until it is recovered at base.
Hexacopter
Quadcopter
Manned Aircraft Vehicle
Fixed wing UAV
30sEditDelete - Q3
In the operational pattern of UAV’s, Dangerous roles means
that someone is either trying to bring down the aircraft or where the life of the pilot may be at undue risk operationally
the task requires long hours in the air, making manned flight fatiguing, stressful, and therefore not desirable
used in research and development work in the aeronautical field
the environment may be contaminated by chemical, biological, or radiological hazards precluding human exposure

Dangerous rolls
Research roles
Dull roles
Covert roles
