At dawn, the tarmac at N'djili International Airport in Kinshasa stirs to the roar of an Airbus A320's engines. In the cockpit, Captain Arnaud Cassellé adjusts his controls. The sky is clear, and communication is smooth. The flight proceeds without incident.
For Cassellé, a seasoned airline pilot, such routine has not always been guaranteed.
"I have been operating here for seven years," he says. "Things are clearly improving. The runways, the instruments, everything is getting better."
Not long ago, crossing the Democratic Republic of Congo (DRC)'s airspace could be challenging. Today, that is no longer the case. The quality of operations at N'djili, the country's principal airport and gateway to the capital, now matches that of major African hubs. Equipped with TopSky aerial surveillance technology, Controller-Pilot Data Link Communications (CPDLC), a new fire station and an independent power plant, Kinshasa's main airport now operates with remarkable efficiency.
The transformation has been driven by the Priority Aviation Safety Project (PPSA II in French), which is backed by approximately $105 million in financing from the African Development Bank Group, in partnership with the government of the DRC.
The Project has also delivered improvements at several other airports across the DRC: Kisangani, Kindu and Mbuji-Mayi, where a 2.3-kilometre runway has been fully upgraded. But the effects are most visible and immediate at N'djili.
Staff in the control tower at N'djili now work with state-of-the-art instrumentation, enabling smoother traffic flows, safer stopovers and greater confidence in air safety across the country.
PPSA II has done more than modernise existing infrastructure. Eight new radio channels have been installed to improve flight safety and facilitate smoother air transport. At Kindu, new facilities and rigorous training have strengthened emergency response capacity. At Mbuji-Mayi, the upgraded runway has already reduced travel times for passengers and cargo alike.
The project's Impact extends beyond renovated runways and new control tower equipment. By enhancing aviation safety, PPSA II is helping to stimulate local economies through increased traffic and more reliable routes. Congolese businesses are benefiting from more efficient logistics, while communities across the country are gaining better access to emergency medical transport and other essential services.
Safety first, then sovereignty
At the offices of the Régie des Voies Aériennes -- the DRC's air traffic control authority, Nadia Bamuongo is quietly confident. An air traffic controller and head of the instructors' department, she says the improvements are as symbolic as they are technical.
"I can confidently say that with the equipment we have today, we are on an equal footing with many countries in Africa," she says. "It is no longer true that Congolese airspace is a black hole."
For Bamuongo, each successful flight and each safe landing carries personal significance:
"I feel a great sense of satisfaction at the end of the day, knowing that planes have landed safely and passengers have reached their destinations. That's what matters to me."
For Alexis Sangi Matanda, project coordinator at the Régie des Voies Aériennes, the contrast between the pre- and post-PPSA II era is unambiguous.
"Often, pilots who crossed our airspace talked about black holes," he says. "But with financing from the African Development Bank Group and the commitment of the government, we have deployed equipment that does more than improve communications--it meets navigation and monitoring challenges."
Upcoming phases of the project will expand radar coverage, continue infrastructure modernisation, and provide training for aviation professionals throughout the country.
"We expect to receive new radar systems in the near future, which will make air traffic control even more precise," says Captain Cassellé.
The hundreds of flights that cross DRC airspace each month now do so with confidence. Airports are busier, staff are better trained, skies are safer and air traffic is growing, creating new opportunities that make a difference for ordinary people.
"Air transport is not just about technology," says project coordinator Matanda. "It's about dignity, connection, and opportunity."
With the support of the African Development Bank Group, the DRC is asserting its air sovereignty and opening new prospects for growth and openness.
