This method called “CAVOC” has been developed by DSNA/DTI, in collaboration with the Air Force and has been approved in 2021 by the STAC.
The method used by FRACS distinguishes from the competitors thanks to the use of a light and easy-to-use drone. An expert, a suitcase and FRACS can come and calibrate your PAPI sets!
Our simple and easily reproducible technique offers undeniable advantages in terms of speed of implementation, runway occupation time (1 hour per PAPI set), accuracy and impact on airport activity compared to the nacelle method or flight control.
The method is rather simple, it is based on an automatic detection of the colorimetric transition in real time, by image processing algorithms. This process allows a real time adjustment of the PAPI.

Since 2019, this method has been tested on military airfields and some civil airports (Castres and Toulouse Francazal) and has entered in its commercial operation phase since July 2022.
Thanks to the numerous advantages of this innovative technique, two airports have already used our services (Libourne and Tarbes Lourdes Pyrénées).
