Meanwhile , why spend time exchanging points of view and trying to blame GVTs and Flight Crew members , the Flight Training Industry offers an extensive flight training courses online at no charge,,find here some links that can be very helpful to enhance your operating skills .Runway excursions are usually lack of communications between pilots and controllers. For example , if the Wx is to be blamed , how come ATC didnt announce Braking action on landing clearances, AA 321 clr to land , braking action poor (fair or good) or braking action should be recorded on airport ATIS.That certainlly helps everybody and avoids runway excursions. Another useful safety tool is to calculate VHP prior landing .
VHP= Hydroplaning Speed.
