You have a plane to catch.
It’s leaving precisely at 12:55 pm. You look up as you race for Concourse C. Thankfully, there’s a Masterclock analog clock tied into the airport terminal’s computer system. In fact, every airport clock and time keeping device is tied into this centralized system. And they are all synchronized to the split second, getting their time reference from atomic clocks aboard orbitting GPS satellites. You can’t get more precise synchronized time than that!
You still have time to make your plane. You can be confident that airport time is your time, even when storms block GPS signals. Whenever that happens, internal crystal oscillators take over, providing the “beat” to keep those second hands moving without missing a millisecond.
And that goes double for Air Traffic Control.
They’re not trying to get to a plane. They’re trying to find a precise time slot for every plane to use their runways and airspace — while keeping a very tight schedule. It’s hectic up there with split-second decisions and communications being called out in a constant stream. Thankfully, with full synchronization, it’s all as if everyone was looking at the same clock. So they know when to turn, when to descend and when to leave the gate.
And that goes for airports around the world. Masterclock digital clocks are in several of these control towers in the USA, throughout Canada, and around the world, making sure that everyone, and especially every pilot and air traffic controller, are watching those seconds and minutes tick off in precise lock step.
All are keyed into UTC (Coordinated Universal Time) based on the Prime Meridian in Greenwich, England. Airplanes pass through so many Time Zones every time they fly that one global time standard is the only way to make sure they’re all on precisely the same time. And that’s also why all pilots and control towers communicate in English. One standard solves so many problems.
Time is important. That’s why we’re in this business.
