What are "push" notifications?

"Push" notifications are emails sent to all your devices to remind you to close a VFR flight plan. If you activated a VFR flight plan using ForeFlight Mobile and have not closed the plan 20 minutes after your calculated ETA (Departure time + ETE), ForeFlight will send a “push” notification to your devices reminding you to close your flight plan. You can close the plan using the “Close” button on the File & Brief page, or by calling 1-800- WX-BRIEF.

If the plan still has not been closed 30 minutes after your calculated ETA (Departure time + ETE) Leidos will send ForeFlight an “OVERDUE” status update, and ForeFlight will then send another “push” notification to your devices reminding you to close your flight plan immediately.
