A glitch in an iPad navigation application used by pilots caused 74 flight delays at American Airlines. The issue, which occurred on Tuesday and Wednesday, was resolved by Wednesday afternoon, according to CNNMoney.
In some instances, pilots had to return to the gate to get a WiFi connection to access a digital map while others had to rely on paper instructions.
The airline switched to a paperless program in 2013 and says that 8,000 iPads have replaced over 24 million pages of documents. The devices are used to communicate flight plans and for navigational purposes. American estimates the switch has saved nearly half a million gallons of fuel.
American Airlines said a third-party app, not Apple, caused the problems and that the glitch only affected a small portion of company's 6,700 daily flights.
