ForeFlight follows the AIRAC 28-day cycle schedules for issuing data updates.
New data becomes active at specific changeover times according to published regional standards. The changeover time used on your device depends on the device’s current geographical location, not the location where the data applies.
For example, new European plate data becomes active at 0901Z (according to the U.S. standard) if the device is currently located in the U.S.
|Europe, South Africa, Brazil, and Taiwan
|1200Z the day before 28-day cycle changeover date
|New Zealand, South Korea
|1600Z the day before 28-day cycle changeover date
|North American regions and other regions not mentioned above
You will be able to download data updates inside ForeFlight Mobile four days ahead of time—on the Sunday before the cycle changeover date. If you download data early, it does not display inside the app until it becomes active. The first time you open ForeFlight Mobile after the new data becomes active, the new data starts being used and then the old data is automatically deleted from your iPad or iPhone. You don't have to perform any additional steps.
