How we Operate

Each of our pilots hold a Remote Pilot Qualification (RPQ-s) and public liability insurance is in place to cover all flights. Every flight undertaken adheres strictly to the Civil Aviation Authority's (CAA) guidelines as well as our own safety procedures set out in our operations manual. All flights are flown with a two person crew consisting of an RPAS Commander and Pilot to maximise safety. Safety is paramount to every operation conducted by Fera.

Through meeting these specifications Fera has been granted Permission for Aerial Work from the CAA.

Operating procedures

Before conducting any flight the Fera UAV team will undertake the following:

  • Discuss customer requirements and set out how we will achieve these
  • Carry out a pre-flight survey to ensure that the project is feasible
  • Compile flight plans to ensure that the area of interest is fully covered during UAV flights
  • Check that we have the land owners permission
  • Confirm a day to undertake the flight in line with predicted weather forecasts
  • Check the airspace and NOTAMs to make sure that it is safe to conduct a flight
  • Carry out an onsite survey and risk assessment
  • Carry out pre-flight checks on the UAV
  • Launch the UAV and start collecting imagery

Our Pilots

Paul Brown MSc, RPQ-s Qualified Pilot

GI Remote Sensing Scientist

Paul is a GI Remote Sensing Scientist at Fera with an extensive range of experience in Remote Sensing, Image Processing and GIS analysis. Leading and contributing to an assortment of projects including; UAV tree species classification for inspection targeting, agricultural land cover mapping for Defra, a temporal palm tree health study in Mozambique and individual crop counting from UAV data for future yield estimating. Prior to joining Fera in early 2014 Paul worked for Airbus Defence & Space, gaining a wealth of experience from a broad variety of Remote Sensing and GIS consultancy projects. Paul is also a CAA-approved commercial UAV operator.

Lee Butler MSc, CGeog (GIS), FRGS. RPQ-s Qualified Pilot

GIS Specialist

Lee's background is in GIS, spatial data analysis and cartography. Lee has been working in the geospatial field for over 10 years, he is a Chartered Geographer, specialising in GIS and a Fellow of the Royal Geographical Society. Lee's recent work at Fera has focused on developing a mobile data collection solution for field workers using hand held GPS devices, smartphones and tablets. Current focus is around the use of web mapping and web applications for the dissemination of imagery and spatial data. Lee is also a CAA-approved commercial UAV operator.

Meet the UAV

Quest Q-200 AGRI PRO

The Quest Q-200 AGRI PRO is our fixed wing UAV. It is capable of carrying a twin sensor payload able to collect multispectral imagery at a resolution of 2.5 - 5 cm, depending on the altitude flown. Its fixed-wing design means it is able to fly for longer and faster than rotary UAVs and in wind speeds up to 25mph. The Q200 is flown with a two person flight crew consisting of a RPAS-Commander and a UAV Pilot.
