RPAS Program
So Let's Dive into the program
RPAS - Remotely Piloted Aircraft System
FAA Definition: Unmanned Aircraft (UA) system that is operated by a pilot via ground control or on-board computer.
-
Fly under 400 feet above ground level
-
Not to fly < 5 nautical miles around airport
-
Aircraft < 55 lbs.
-
Fly during daytime or night time operation with appropriate lighting
-
Fly visual line of sight ( VLOS)
-
No flight over non-participating people
FAA Part 107 Rule *
RPAS as Platform
Multi-rotors
Fixed-wing & VTOL
- Shorter flight time (< 45 min)
- Cover smaller area
- Highly maneuverable
- Less expensive
- Access to confined spaces
- Long flight time (+ 40min)
- Covers very large area
(vertical take-off & land)
