the Moach way of doing this is to set the default flight to be the point where you last left FS....
i. e. if you fly to KMIA, park at the gate, switch all systems off and quit the game, when you come back that's where you'll be and the plane will be cold and dark.... or if you leave a flight in middair, you can pick it up later

this way you can be always on a continuous flight
to do this go to the "select a flight" screen and select "previous flight", then, check the "make this the default flight" box
cheers and may your main gears always touch down first
