What's the difference between the "Cleared as filed" vs "Expected Route" messages received in ForeFlight

 

Cleared as Filed vs Expected Route

Cleared as Filed - This means the routing will be what the pilot originally filed in their flight plan (or as later amended) and does not relate to an expected clearance. Routing that is "cleared as filed" is an ATC function.

Expected Route -We provide Expected Route notifications when we receive them from the ATC systems. You can elect to ignore or accept the “expected route”.

If you 'Accept' the Expected Route in the push notification, please be aware that the Expected Route is only a notification - your originally filed flight plan is what ATC expects you to fly if they issue you a clearance of “as filed”.  "Accepting" the expected route simply updates your Flight form in ForeFlight Mobile such that the proper performance numbers can be calculated.
