A/c are parked with the brakes on [unless hot!]
Sorry, but most strongly disagree, respectfully.
In the 42 some years that I have flown I only set the parking brake until chocks are inserted under the gear. Then the brakes are released.
Smart engineers leave the chocks about 2 inches [50mm] from the tyres so they don't get jammed!
Now on this statement I agree. Even then the aircraft will roll onto the chocks causing problems. There have been occasions that a tug had to be used to push the aircraft back to enable the chocks to be moved.
Once on a 727 we had to have the main tires changed because an old tubular metal chock was used and the chock failed cutting into the tires.
Now, to answer the question posed by this thread. No.
