Enaire Satellite Procedures Disrupt Alvedro Flights and Renew Calls for Cat III ILS

Higher decision heights in the new satellite approaches are being applied in practice, increasing diversions as Enaire studies whether to implement Category 3 ILS.

Overview

  • Two recent diversions to Santiago and Vigo disrupted Alvedro operations and affected passengers on Thursday, June 18, as crews aborted approaches that could not reach the new decision heights.
  • Local campaigners and some crews say Enaire’s satellite-based procedures, published in late April, raise minima and move the pilot decision point near Montrove, creating 'false minima' that force earlier go-arounds.
  • The contested change increases the decision height for common types such as A320/B737 from about 210 to 233 feet, a shift Vuela Más Alto says effectively becomes roughly 300 feet once terrain geometry is applied.
  • Enaire says the procedures are part of Europe’s move to Performance-Based Navigation and that safety and operability are preserved, but it has not fully withdrawn the new approaches and has opened a technical study on Cat III implementation.
  • Alvedro is technically certified for Category 3 ILS but currently operates only Cat I/II; local leaders warn that without Cat III the airport will keep suffering weather- and procedure-driven diversions and wider travel disruption.
