BEagle,
Just to let you know that about 4 years ago, JEFTS groundschool did alittle bit on the DC, however, for the previous 6 months all us poor Navy Students had been getting a complete beasting on the Computer. Stuff like: ' your boat was there, then, you are here, now with x fuel in US gallons, given this met, when could you land on the boat with x left in the tanks??' It was a bugger, but quite good to get your head round the threoy behind the math. As for Fast jet mates not using the DC for wind.... does a 20kt wind affect you guys at 350/450kts??? It does affect at 90kts, but the MDR 'suck it and see' with the conditions DOES work well!!
Regards
