Snave is steering you in the proper direction.. This is where simming becomes real fun, because this is where realistic piloting can be practiced. This is what I appreciate most, because it makes you THINK in terms of piloting instead of just joysticking a jet around. Most of the work is done before you even start the engines. Flying is the easy part (and actually the most boring part in jets, as most of it is done by the autopilot) (another reason why I prefer simming in small, slow airplanes... spending the majority of a flight on autopilot at 35,000msl gets old) Pouring over weather briefings and forecasts so that you can calculate the head/tail-wind component... calculating your fuel burn based on this (and your load).. planning for a stepped climb if on a long flight starting with lots of fuel.... reading through the logs you've been keeping on each airplane, so that there's no guessing about how thirsty it is, and what adjustment to all the V-speeds work best... using your experience for a throttle-setting and pitch angle that will keep you from busting 250KIAS on you climb-out (without making your virtual passengers wonder what cereal box you got your license out of)... planning your descent to not bust speed restrictions on the way down.. and of course flying a smooth, precise intrument approach when the visibility is poor.Truth be told.. unless you practice almost daily.. a entire, realistic jet flight almost requires a co-pilot, even in the sim. There is a lot going on, and it all happens very fast when you enter an airport enviroment, and can't see past the nose cone. Airspeeds and flap deployment timings are CRITICAL.

about the fuel.. thats what I exactly do... pencil and paper and trying to plane my fuel... so I wasn't that far from truth like i thought.... Thank you all for help and advice... looks like I know everything I need for now....
