In 2007, Aena Internacional created the In-flight Verification Unit (IVU).
The Unit has the capacity to verify Systems such as:
ILS (Instrumental Landing System) Categories I, II and III.
Radio markers: En route/ILS Marker (MKR).
VOR (Very High Frequency Omnidirectional Range), conventional and doppler.
NDB (Non Directional Beacon).
DME (Distance Measuring Equipment).
VHF/AM communications (VHF), broad bands 8.33kHz.
PAPI (Precision Approach Path Indicator).
VASI (Visual Approach Slope Indicator).
The unit is also equipped to verify conventional instrumental procedures (SIDs and STARs based on VOR, DME, NDB) and RNAV (B-RNAV, P-RNAV, RNP, including those based on GNSS/SBAS), as well as to analyse interference on VHF, UHF and L bands.

Aena International's In-flight Verification Unit officially began providing in-flight verification services in Spain
This made Aena Internacional the first Spanish civil suppliers of in-flight verification services for air navigational aids.
Having consolidated its presence in Spain, the Unit has been working for third countries including Morocco and Oman since 2012.
What verification services are used for
They check from the air that air navigational aids installed on the ground (radio aids) are working correctly and in accordance with ICOA recommendations
They can safely be used by aircraft conducting instrumental flights supported by them
These checks are conducted before commissioning radio aids and then periodically.
The Aena Internacional unit provides a high-quality and availability service for Aena and ENAIRE
