Is there someway to have the parking brake on when you select an A/C. Some turboprops have an annoying habit of creeping forward.

Dave. Tried that but no luck. Unless I am doing ir wrong. Checked fsx cfg but all mention of brakes are marked true.I am at a loss.In fs9 when you selected an a/c it always came up with the parking brake on. How did they do that in fs9?

FS9 and FSX work the same way in this regard, as I explained above. Your parking brakes were set in FS9 because the default 'default flight', C172 @ KSEA, had the brakes set.  In FSX the default is the Trike flying over Friday Harbor so no brakes set.

So you have to create a new 'default flight' with the settings you prefer:

In the Free Flight window, make the selections you want, aircraft, location etc., so your parked at an airport.  Click fly now.  

When your in your cockpit, set your systems (engines, electrical, lights, etc.) as you like, and set the parking brake. When you have things set the way you want, save the flight, putting a check mark next to 'Make this the default flight' before clicking OK.

From now on, in any flights you CREATE in the Free Flight window, the parking brakes will be set, as well as any other conditions you had set.

This will have no effect on any flight you 'Load' from 'Saved Flights'. For those you'll have to make the desired change(s) and resave the flight.

PS. The 'mention of brakes' in the FSX.cfg file relate to the messages displayed in the flight window, not to any brake condition of an aircraft.
