Transportation Secretary Pete Buttigieg has expressed concerns about potential delays or cancellations resulting from the altimeter requirement, stating that it represents the most significant foreseeable issue affecting performance during the summer. The extent of the impact will depend primarily on weather conditions, although it is worth noting that significant snowstorms are not anticipated in the near future. Ultimately, all aircraft operating in the US will need to have updated altimeters by February 2024, regardless of visibility conditions.
