PAPI lights inspection, by drone
A fully managed service with certified operators. Regulatory-grade measurement of angle, photometric intensity, beam transition and position, built to ICAO, EASA or FAA, with same-day reports.
One service, both halves handled
WE COME TO YOU
Our crew, our equipment
Certified professionals bring the drones, the cameras and the measurement gear to your airport. No drone purchase, no training, nothing to set up.
Measurements, not impressions
Footage goes straight into the measurement pipeline, and the protocol comes out the same day in the format your authority expects.
From mission to verified calibration
HOW IT WORKS · 6 STEPSGenerated from your airport profile and PAPI positions, collision-free by default.
The drone flies the mission autonomously, recording each PAPI unit from multiple angles.
The field hub pulls the footage back over the airfield network automatically, no cards to carry, and processing starts right away.
Angular and beam-transition measurements plus RTK position, extracted from the footage.
A report in your authority's format, ICAO, EASA or FAA, with exact adjustment values per unit.
After corrections, a re-measurement confirms every unit is back in tolerance.
What the report answers
The glide slope rows of the visual aids protocol, each with the tolerance it is judged against.
The angle each unit is set to, and the nominal glide path the four units produce together.
The angle at which a unit changes from white to red, measured across the transition rather than read off it.
The angular spacing between neighbouring units, which is what sets the width of each signal step in the pattern.
An aircraft flying the ILS glide path stays inside the on-slope sector the PAPI indicates.
Each unit emits the correct colour, and no red filter has faded to the point where the beam is out of specification.
Light intensity per unit and the ratio between units are correct, with all four set symmetrically.
The signal stays visible across the sector either side of the runway axis.
The signal stays visible on the runway axis through the whole approach elevation band.
Every unit changes intensity together and by the commanded step, in step with the rest of the airfield lighting.
The signal seen over the threshold matches the published minimum eye height for the runway.
The obstacle protection surface is clear, so visual contact with the runway is kept all the way down the approach.
No light near the approach can be mistaken for the glide slope signal, and none dazzles the crew.
Built for both sides of the runway
Airports get compliant inspections without closures. Certified drone operators get a new service line through the partner program.
