The Ground Data Black Box® (GDBB) Tempeus® aims to close safety gaps.
The aviation industry has created 2 flight recorders that are the black boxes onboard: the flight data recorder (FDR) and the cockpit voice recorder (CVR). But there is one problem, one black box is missing to cover the ground configuration of an aircraft. It is The Ground Data Black Box®. Keitas Systems has created this ground data black box : Tempeus®.

The Ground Data Black Box® Tempeus® is the third safety data recorder, the third black box that did not exist yet in aviation. Some Dassault Aviation Falcon airplanes (F900LX and F8X) are equipped and certified with the GDBB Tempeus® since 2017.

Tempeus® records the ground data parameters to complete the safety analysis of the two black boxes onboard, to manage and increase the aircrafts safety. It is a new safety standard in aviation, because flights safety start from the ground©. The Ground Data Black Box® Tempeus® was officially introduced by the French government in October 2022, to the International Civil Aviation Organization (ICAO) to issue a new safety standard (SARPs). The Ground Data Black Box® Tempeus® is still under evaluation at ICAO.

NATO is interested by The Ground Data Black Box® Tempeus®. Lahou Keita, FRAeS was invited at NATO Headquarters in France in September 2023.

Tempeus® records the ground data, that is to say, the evolution of the aircraft’s configuration since the manufacture exit, in order to detect and correct the ground safety issues, to protect the crew, and the passengers. The ground data black box® is always available to be open first, while locating the other two.

We recommend Tempeus® on-ground health monitoring for all aircraft in the world.

The Ground Data Black Box® secret has been revealed to the Boeing teams and to the Consulate General of Canada in Seattle teams, during the Boeing Launchpad Canada program.

Tempeus® is also a proactive and reliable online tool for monitoring your fleet maintenance works. Get real time information about the works in progress wherever the service center is located.
