Reposting this from a Facebook post. ForeFlight keeps making it easier, take a look at this airport info feature from the flight plan screen.
You can quickly activate ForeFlight's Plates on Maps feature without leaving the Maps view. Tap on an airport bubble in the Route Editor and select "show plate" to browse from a list of airport diagrams and approaches.
I decided not to post the associated video because it was too short and no sound. I think screen shots from my iPad mini3 are easier to see and follow along.
The one change I do not like is the elimination of the reverse button and instead replaced with the Estimated Time of Departure (ETD) button. ETD can be selected or changed when you file, no need to see it here.
