Questione giuridica chiave
Whether the company had standing and the federal appeal was admissible.
Decisione estratta
The company had standing because the amendment could affect use of its land through noise-protection rules; the appeal was otherwise timely and directed against a final cantonal decision.
Motivazione estratta
The contested plan could potentially constrain the appellant's parcel, so special affectedness existed; no exclusion under Art. 83 LTF applied.
