I've read about a lot of problems with the DC-8 packages. And if you are trying to use fuel management from the manual, well, good luck with that. For example, if there's an explanation about what positions the fill valve knobs should show when open and closed, I admit I missed it. (X on 1 and 4 are closed, plus is open; vertical on 2 and 3 are closed, horizontal is open.) And it does get a bit vague on the details. Now, I'm not a technical guy, so I can't fix anything. What I have learned is how things actually work. Trial and error. I just flew a 12 hour flight from Newark to Buenos Aires in the DC-8-62 and arrived with expected fuel more or less equal in the mains. It was a blast.
All I'm saying is that before anyone writes off these two packages covering the entire history of the Douglas icon, don't believe you can't manage fuel, or have to use CTL-E, or whatever. No, it is not the most technically accurate DC-8 available. Yes, it has its problems. The ones I used to think were show-stoppers aren't. Just my opinion, but I think it is one of Just Flight's best survey sims and the one I prefer. The early models are fun for shorter flights and you don't even need fuel management if you can get there on whatever the mains will hold. For longer flights, I can't go into my fuel management gouge here, and I'm not claiming this product doesn't require a bit of devotion. What I am saying is that I have a whole lot of airplanes (some costing a lot more even for the DC-8's two packages and livery additions) but this is my go-to airplane. (Yes, i also fly another DC-8 when I'm in a serious mood.)
Did I mention I'm using it in P3Dv5.2? Suh-weet.
