Time: 1100 (UTC)

The Aviation Industry is one of the industries with an unending 24-hour cycle split into shifts on a rotational basis. Regardless of the time of day, Pilots around the world continue to fly, Air Traffic Controllers manage the airspace by keeping watch and keeping airplanes safely apart, Safety Engineers work diligently to keep CNS equipment serviceable, Airside Operators marshal and push back aircraft, RFFS personnel remain on high alert etc. Inside terminal buildings are Check-in Agents, Aviation Security Personnel, Immigration Officers, Customs Officers and State Security Officials who also work round-the-clock to keep the industry safe. How can aviation professionals stay in good health and a state of well-being to be able to perform their duties effectively? What lifestyle changes are required to improve quality of life? What are the general industry-related health risk factors?

Join us for the 7th episode where we will host three esteemed Industry experts to give insights on the topic and help answer these burning questions and more. 

During this webinar, we will feature Technical Experts on the African Continent who were at the forefront of dealing with the covid-19 pandemic at both National and International levels: They will be sharing their thoughts and experiences on lessons learned and how their organizations emerged through very challenging times as well as giving insights on how to build resilience going forward. 
What is our preparedness level and are we as an Industry adopting a proactive or reactive approach in dealing with any future pandemics which may spring up along the way? 
Please join us to find out!

The use of unmanned aircraft systems for civilian purposes has become prevalent within the last decade. Drones are gradually becoming a part of our lives with applications and uses in agriculture, aerial surveying, drone journalism, search and rescue, remote inspections, and medical supplies to inaccessible communities among others.
The expected explosion in civilian drone/RPAS use within the next few years is set to challenge and redefine airspace classification, use and management.
How is this technology being used to improve the lives of people living in Africa? Be it for commercial or recreational purposes, what regulatory framework governs the use of drones and RPAS? Are these regulations known to enthusiasts and Drone/RPAS vendors? How are drones and RPAS integrated into the airspace vis-à-vis manned air traffic to achieve safety and what effects do drones have on the safety of manned aircraft? Are there privacy and security concerns regarding the use of drones?
In this webinar, Melissa Rusanganwa from Zipline will share the experiences of Zipline in their novel use of drones to deliver badly needed medical supplies to remote communities across Africa. John Kwofie, an Air Traffic controller from the Ghana Civil Aviation Authority and a member of CANSO/AFI RPAS TASK FORCE will discuss ATM, safety issues and RPAS integration strategies whiles Raynold Senam Atadja, a Senior Aviation Safety Inspector and a member of the ICAO RPAS panel will discuss regulatory issues regarding present and future drone/RPAS use.
