For those talking about water in the fuel tanks -- the bae146 fuel system is designed to pick up water , mix it with fuel and send it to the engines --- it does this by using jetpumps in the output of the boost pumps -- these jet pumps are a small venturi devices sucking fuel from the lowest point in the fuel tanks , sending that small amount of fuel and water to the highest part of the fuel tanks ,to a header tank - thus keeping any minute amount of water in the fuel mixing all the time with the fuel and when it reaches the engines is safely expelled = licence lame on 146
