The instrumental system validation tests have finished this September

Aena Internacional, together with the UPM, have validated the modified instrumental maneuver flights at the Andorra-La Seu d’Urgell Airport. Last year, PAPI’s were calibrated (visual help that provides an approach slope installed on the side of the track) and the first week of September, PAPI calibration flights were resumed to adjust, Analyze the values ​​analyzed in the theoretical study. The results obtained were satisfactory, which made it possible to validate the flight on September 16th.

The manoeuvre is based on the global navigation satellite system (GNSS). GNSS is a constellation of satellites that transmit signals used for the positioning and localization in any part of the earth globe, be it land, sea or air. These allow to determine the geographic coordinates and the altitude of a given point as a result of the reception of signals from constellations of artificial Earth satellites. This allows the aircraft to be controlled at all times and emit signals even if the visibility is low.

With all this, the airport wants to facilitate access to airlines at the airport in situations of poor visibility, in order to attract commercial aviation (for passenger and freight transport). This means that, if so far low-visibility aircraft could not land, now they can land if they have GPS systems on the plane. Currently, at 12000ft if the aircraft do not have sufficient visibility, the operation must be cancelled, with the new instrumental manoeuvre the aircraft will be guided up to 7,000 ft.
