Flight simulator is not ACS..
True. But..
Getting used to how an aircraft reacts, and getting used to the steps for scanning provided in your blue ACS booklet, will help when you get into the machine in Trenton.
Be it a stick, or a yoke on your simulator, knowning that forward goes down, and backwards goes up, and having that in muscle memory will save you fractions of seconds at the ACS center when you are doing your tests. by the time you've thought.. "Too much pitch down.".. What do I do? "Pull back slightly. and then do it.. you'll already be another 100-200 feet from where you first noticed you had too much pitch down.
There are some settings someone provided on this board, use those settings, get used to the instruments and basic handling charactersitics.. run the first few lessons through several times, and then when you get in the machine in Trenton it will be a little more familiar then if you had not done it.
