[Turn] US F-22 postponed to Japan due to date change line computer calendar chaos "birds of prey" aircraft silly

Original

An inconspicuous little news and an inconspicuous little bug are worth thinking about. ^_^

The F-22 "birds of prey" of the US military is the most advanced fighter in the world. It has stealth performance and is equipped with advanced radar and weapon systems. The fan engine it is equipped with is very efficient, so that it can not be enabled
In the case of force. But a seemingly inconspicuous incident caused six F-22 "birds of prey" fighters to fail to complete 12 to 15 hours from Hawaii to Japan's Okinawa kakana base in February this year
Flight: the International Date change line makes us air force's most powerful fighter aircraft useless.
In order to avoid the phenomenon of "date disorder", the international unified regulation of 180 ° longitude line is "international date change line ". When you cross the international date change line from west to east, you must subtract one day from the timing system. Otherwise, you must add one day to the international date change line from east to west.
When the "birds of prey" fighter fleet crossed the international date change line, multiple computer systems on the machine collapsed due to calendar issues, and the fuel subsystem, navigation, and some communication systems completely failed. The pilot has performed many times
And cannot restart these systems. Fortunately, the weather on the day was very good and there was no problem with visibility. In addition, the tankers that refuel the "Birds" fighter fleet guide them to safe locations. Retired U. S. Air Force Major General
"If the weather was bad at the time, the situation would be very serious," he said. The air force solved the problem within 48 hours. This was a minor fault in a computer system. Someone made a mistake in the code, which caused
A series of faults ."
They are lucky for the "Birds" fighter pilots because, in practice, they may be shot down due to a code error.
