Using wheel brake to prevent jerking forward and possibly over-running the rope is a useful technique especially when launching on a down slope. With a glider such as the ASW20 where wheel brake is engaged by fully opening the air brake, the glider will be seen to start the initial take-off roll with air brakes fully open - but closed and locked as soon as the combination is properly under way.
