Use of RPAS* for Wastewater Treatment Division

November 15, 2023

FAA Part 107 Certified Remote Pilot

Remotely Piloted Aircraft System*

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)

Why Use Drones?

Easy - Simple with little effort

 

Efficient - Results without waste

 

 

Effective - Producing Results

Why Use Drones?

1. Easy - Simple with little effort

Automatic

Repeatable

Flight Control App  

  • Automate Flight Planning - Fly Consistently for overlapping images
  • Can fly manually but it's like mowing with scissors

Example: Auto flight plan

Result 3D Model

Why Use Drones?

2. Efficient - Results without waste

Safety of staffs

Save Time & $$

Data Processing - Efficient  

  • Cloud Storage & Cloud Data Processing
  • Flight Planning from Desktop - fly on Mobile (controller)
  • Cloud storage/Cloud Processing 
  • Centralized System
  • Project Deliverables
