Per default the anti skid switch is in the on position. You must have turned it off accidentally. When the switch is off you have not steering and no anti skid.
The auto brake strength is not stronger because of that. The strength is variable and decelerates the aircraft at a near constant rate. Medium is a good deceleration but if you try to land short then you probably need manual brakes.
I should have accidentally turned it off ... So why is the 1000PSI notice due? What does that mean in Ecam? I set the brakes half because it was a short track like telluride .. But why was the legend erased when I turned the anti skid ON? It is incredible I love this plane .. I congratulate you it is so realistic it seems that it was a pc simulator plane .. No mobile simulator compares to you .. You are by far the best 👏👏👏👏👏👏👏👏👏 thanks IPACS
