Fly to any address from nearby airport.

Squirrel has a Youtube video showing a longer and more difficult method to create such a flight plan. He edits coordinates in .pln and .flt files using a text editor. But none of that is actually necessary using this quicker method.

For any street address, (let's say 1600 Pennsylvania Avenue):

Open google maps, type in address on the left and then right click on the location icon on the map over on the right, then click "What's Here".

That will show you the coordinates of that street address, click on it.

That will place the coordinates over on the left of Google Maps nav box, right mouse click on it and select Copy (or Control C).

Paste those coordinates (38.896866, -77.036627) (use Control V to paste) in the Search box inside MSFS World Map (the main window of MSFS), and click "SET AS ARRIVAL".

That will place the address' coordinates in the MSFS box: Fly To.

Go back to Google maps, retype the address (1600 Pennsylvania, Ave) and click (below) on "Nearby".

A search box pops up, type in 'airport', all airports near 1600 Pennsylvania will show up over on the Google map on the right.

Type the name of an airport seen on the Google map (let's say Ronald Reagan International) into the MSFS search window (you might have to 'fiddle' with name a bit for MSFS to recognize the airport).

A list of airports show up, click on the proper one, and select SET AS DEPARTURE.

That will place Reagan Intl. into the MSFS box: Fly From.

Now you can fly the plan, airport departure to address arrival (flyover) or SAVE the plan after choosing weather and time of day, etc.
