• Communication and Data Exchange: Efficient, reliable and effective communication between air traffic control, drones and other aircraft is crucial. By establishing protocols that allow real-time sharing of data on flight intentions, altitude and position. Satellite communication and 5G networks can play a pretty significant role in improving this connection in remote areas.
• Regulatory Harmonization:  Reoccurring regulations spanning across African countries are essential to ensure standardized and safe drone operations.
• Airspace Classification: Drone operations having defined specific airspace classes, considering values like proximity to airports and population density.
• Licensing and Registration: Clear requirements for drone operators should be established, including registration of drones, pilots, training and certification.
• Operational Rules: Drone flight rules should be defined, including visibility requirements, speed restrictions, and altitude limits.
• Liability and Insurance: Liability in case of accidents should be determined while establishing insurance requirements for drone operators.
• Operational Procedures: Clear and precise procedures need to be developed for both drone operators also air traffic controllers need to ensure coordinated and safe flights. This includes:
• Flight Planning and Approval:  Flight plans submission, obtaining approval and communications with air traffic control processes need to be established.
• Contingency Plans: Procedures for dealing with airspace intrusion, loss of communication, drone malfunctions or any other emergencies should be developed.

Challenges

Several significant challenges will be faced by Africa's ATM system concerning the integration of drone:
