It costs a small amount (~ £20) but if you buy the Garmin G1000 simulator for PC you can have two screens (set up as the PFD and MFD of course), use a joystick or yoke to fly the plane, set starting airfield etc. - a much better simulator in this setup than trying to run it on an iPad in my opinion.
Go to the Garmin website and search for G1000 PC trainer - it lists loads of aircraft, with specific trainers depending upon what you are flying.
