my critics think the reason it is important is because suppose you go into a busy Metro Airport and there's nothing going on in that city but say NASCAR race Joliet Speedway and you come into Midway Airport and all three FBO's others want to with aircraft-and aircraft are scattered all over the ramp.
okay and let's say you're flying an Aero Cmdr.make that a Turbo commanderor perhaps a turbo Centurion.

And keep in mind that your refueling is performed by the lowest paid worker on the ramp and also at this time. Overworked perhaps not fully trained and mistakes turbo four turbine and fuels your recip with jet A fuel, believe it or don't, this happens quite often.

So this is the matter of source of diesel cost of diesel it's a matter of safety.the FAA has spent 30 years since the accident at Tenerife trying to eliminate runway incursions yet after 30 years runway incursions still occur. In fact recent statistics indicate incursions may be increasing. If this is the case after 30 years of education infrastructure improvements at airports and education or even improved technologies I think there is little hope for e1iminating errors in refueling.go here to see an article on a certified diesel powered aircraft


http://www.wired.com/autopia/2010/04/diesel-airplane-sips-fuel-like-its-automotive-cousins/ Keep in mind the certification is both European and FAA why this is important to me is not because it's diesel it's because it's a new technology certified for aviation which hopefully means certified water cooled recips and certified rotaries may finally be just over the horizon. So I'm an optimist, but I don't think overly so.
