RE: Fuel Grades

In answer to your question the flash points are different and it is as a result of the additives that are added to the fuel. Different users require the fuel to do different things, the navy for example require a fuel that is safer to store as a fire on board a ship is a much more dangerous affair t...

I don't think that the pilots would have missed a missing boat fairing on the flap track on their walk round, the #4 fairing is a good 10ft long in its entirety. with the flaps up I don't think that the drag penalty would be that high and it is something that the aircraft can be dispatched without. ...

the wipers on a 747 shouldnt be used when the screen isnt wet as thie pre load on them is to much for the blades to cope with and it will rip them of the arm. this is as you might guess bad as it can also damage the screen.
