Many airlines cannot meet a Saturday deadline to equip their fleets with new 5G-tolerant technology.
A messy effort to equip planes with updated technology is threatening to upend possibly the busiest weekend for post-pandemic air travel in the US.
More than 6,000 flights have been scrapped and over 30,000 delayed since Monday, based on data from the FlightAware website.Even as most airlines have since largely rebounded, the days ahead will see wildfire smoke waft over busy airspaces like New York and thunderstorms roil Midwestern states. But airline industry officials have warned the changes could interfere with the radio frequency filters planes use to help pilots determine altitude. Known as radio altimeters or radar altimeters, the equipment is particularly important for landing safely in inclement or low-visibility conditions.In line with these concerns, the FAA directed all carriers to upgrade their fleets with new 5G-tolerant altimeters by Saturday.
"Nevertheless, thanks to careful planning, A4A member carriers are confident in their ability to maintain the integrity of their schedules, despite the impending deadline."
