say. the issue here is the 5g radio spectrum, it operates on a similar part of the radio spectrum to what is called a radar altimeter. there s a critical piece of instrumentation in everything from commercial airliners to cargo planes, helicopters. they all need this to be able to tell their exact height above the ground, especially in low visibility continues, especially in those critical moments right before landing. now, the airlines say we could delay this once more, it was her delayed two weeks, we could also come up with a way to make sure these transmitters don t interfere when the airplane is closest to the ground, turn these off, essentially, near runways at airports. in this letter that airline ceos just sent the department of transportation, they say, quote, the ripple effects across both passenger and cargo operations, workforce and the broader economy, are simply in calculable. the nation s commerce will grind
faa s inability to do what nearly 40 countries have done, which is to safely deploy 5g technology without disrupting aviation services and we urge it to do so in a timely manner. really begs the question here about who is to blame. was it the faa or fcc which allowed this 5g radio spectrum to be used in a way airlines say would interfere with critical systems on board planes, wondering if congress will get involved here. the rollout has become so concerning some international airlines are suspending some flights to the u.s. emirates suspended nine flights to the u.s. it s changing planes on three other flights. ana, air japan, also air india. we also received a message today from american airlines which it sent to its employees which said there could be an enumerable amount of delays and cancellations at that airline if 5g was allowed to deploy as initially planned. it couldn t even pinpoint exactly how many problems this
