Peter is right, the L10 will fly on one engine at "reasonable" weights. In 20 years and more than 10,000 command hrs on the TriStar, have had NO engine failures, and one precautionary shutdown (high vibs)....a really FINE machine...but getting old so will be assigned to the "small" operators to make....a big profit (we hope)...hey, even a small profit would be welcome in today's market.
